5 Best Faucet Water Filter System of 2023: Reviews + Buyer’s Guide

Even if the water supply to your house comes from the pristine foothills of a glacier, there is no doubt that it contains some amounts of contaminants. The problem is that in this “some” amount of contaminants, a few of them could be dangerous chemicals that can cause serious damage to your body. Some could be heavy metals such as lead or mercury, and some could be just inert sand or silt that no one wants to have in their drinking or cooking water. Nevertheless, it is what makes a water filter an important addition to your home and your health.

We have looked at and reviewed not just many filtration systems but many types of water filter systems. For heavy filtration, you can get under the sink water filter. For lighter and easier filtration, countertop water filters are the best. Or, if you really want to have only filtered water in your home, then heavy-duty whole house water filters are the best option. But right in the space where all these filters are differentiated sits another type of filter that takes the benefits of all these filters to some extent; Faucet water filters.

Our #1 Recommendation: Invigorated Water pH Regenerate Faucet Water Filter

Invigorated Water pH Regenerate Faucet Water Filter is a small, compact, and has a powerful filtration unit that comes with all the important features to provide clean water. The filter is easy to install and has a life of 12 months.  

Faucet water filters provide great filtration of under sink water filters without the bulk. They add the great portability of countertop water filters, and the best part is that they also work as a whole house water filter since you can fit them in any facet of your choice and get filtered water there. So faucet water filters are a great addition for filtration. And this is why we scoured the market again, scrutinizing our eyes and our tests to find the best faucet water filter systems for 2023. We looked at every little detail, weighed the pros and cons, looked at the price to feature ratio, and finally came up with this list. So let’s get started with the list.

1. Invigorated Water pH Regenerate Faucet Water Filter

Invigorated Water pH Regenerate Faucet Water Filter
View Latest Price

One of the best faucet water filters that we found is the Invigorated Water pH Regenerate, and we were surprised at how consistent this filter was in being good in almost every aspect of our testing. The Regenerate has so many great things to talk about, from great filtration to great looks. Another great thing about this filter is that the company, Invigorated Water, has a plethora of water filtration products, showing their experience and expertise in making these filters. We got one for ourselves and tested the filter to see if it was worth the price it asked for. Here’s a brief but detailed review of this faucet filter, along with the pros, cons, and our verdict on who should get this filter and why.

Unboxing, Looks, and Build Quality

The first stage that we think matters to some extent is the unboxing experience and the looks. It is why companies spend a fortune in making this experience good. We are glad to say that the filter comes in a well-packed box, and even the quality of the box is great. There is proper packaging and padding to prevent transit damage. All the components of the product speak quality, which is very impressive.

Coming to the looks, we are very impressed with the way it looks. Everything feels great with the brushed aluminum finish and sleek and minimal design. This filter is designed in a way that will make you want to replace your original faucet. So we are giving it full marks in looks.

The same can be said for the build quality. Although the filter is lighter than it looks, it does not feel cheap or of low quality in any way. On the contrary, the weight distribution is done properly, the body of the filter feels solid and sturdy, and every component of the filter feels like it is made to last. That is to be expected since the body is made of stainless steel. The spigot is also strong, and the entire filter has a soft-touch metal feel, which makes the premium feel way more premium.

So, in conclusion, there is no compromise made in the quality or the looks of the filter. We are very sure that you’ll love the looks and quality of the Regenerate.

Looks and quality are just the initial attractors. The most important thing is filtration and how well it does it. Let’s look at the filtration capabilities of the Regenerate.


There’s a lot going on in the filtration department of the Regenerate. However, this is a capable filter on paper. The Regenerate comes with two filtration units, which house different filtration modules. There is one multi-stage PH007 filter, an activated carbon coconut shell filter, charcoal filter, zeolite, and stone and ceramic ball blend. It is an impressive combination of filtration technologies, and it shows.

The Regenerate is capable of removing some of the most common and dangerous contaminants from the water. It can remove chemical contaminants such as chlorine, chloramine, fluoride, limescale, VOCs, etc. Chlorine is the most common chemical contaminant in this lot. The Regenerate can also effectively remove toxic heavy metals like lead, mercury, copper, and arsenic. Note that lead and arsenic are the most toxic in this lot. Of course, this is what every decent filter can do, but the Regenerate has a few tricks up the sleeve that make it better than the rest.

Without a complicated set of filters, the Regenerate can remove sand, silt, dust, and even remove the hardness in water to some extent. The Regenerate can also increase the pH, which makes the water more alkaline. Alkaline water is safer to drink. The filter also reduces the ORP, which is the Oxidation Reduction Potential. Water with high ORP is damaging to the body. So in terms of filtration, the Regenerate does more than what is expected from it. Since chlorine and chloramine are being removed, it also improves the taste and smell of the water.

Testing the Filter

No claim goes untested with us, and since the Regenerate really claims to be an extraordinary water filter, we had to test it properly. So, we prepared our test sample and spiked it with lead, arsenic, chlorine, limescale, and some common sedimentary contaminants. Since we wanted to test all the features, we also reduced the pH of the water to make it more acidic, added some magnesium and calcium salts (for the hardness of the water), and also increased the ORP. The TDS level of the water was around 680, which is way higher than the standard limit. We also added some amount of VOCs to test how good the filter is against volatile carbon compounds. With everything ready, we began the test.

We put the sample in the system, and after a few minutes of filtration, we were ready to check the filtration. First, we tested the TDS, and from 680, the filtration brought it down to a pleasant 105, which is the usual standard. Then we looked for the chemical contaminants. There was no smell of chlorine in the water, which was a great sign. And our tests confirmed the same after testing. The filter had removed more than 99% of the chlorine. Other chemical contaminants were removed just as advertised; we did find chloramine to be more persistent in the sample.

The filter completely removed lead, mercury, and arsenic, and the amount that we had out in the sample was ungodly. So the fact that this simple faucet water filter performed like a full-fledged RO filter is beyond impressive. We are beyond content with the quality and level of filtration. It can effectively remove all the common and dangerous contaminants from the water. Top marks for filtration.

What We Loved About the Filter?

Invigorated Water pH Regenerate Faucet Water Filter user reviwe

There are a lot of things that impressed us, other than the great filtration. So here are all the pros of the Invigorated Regenerate faucet water filter that would make you want to get it.

Mineral Addition

Great filtration is one thing, but the addition of extra minerals such as magnesium and iron makes this filter even better. The process of ionization also reduces the ORP of the water, which is deteriorating for organic matter, including your body. The filter also makes the water slightly alkaline. Alkaline water is generally considered better than neutral water due to its high mineral content.

Filter Life

The Regenerate comes with a standard filter life of 12 months or one year. It will depend on the current condition of your water supply. Hard water with too much limescale will reduce the filter life, but even then, the filter can last easily for nine months. At this size and price, a filter life of a year is very impressive.

Excellent Compatibility

Since this is a faucet filter, being compatible with your plumbing is a very strong factor. It is where this filter shines. The Regenerate comes with 5 of the most common connectors along with a universal connector. It makes fitting this filter in any sink easy and hassle-free. We tried it in three very different sinks and had no issues fitting it.

Secure and Safe

Safety comes with the use of high-quality material. The body is made of metal, and it is 100% food-safe, BPA-free plastic wherever plastics have been used. In addition, security comes from a money-back guarantee. Thankfully, the Regenerate comes with a 60-days money-back guarantee which secures 100% of your investment.


The price was the best thing we loved about this filter. At the time of writing this article, the Regenerate is priced just a dollar shy of $80. But we are certain that you can get it for a lower price with some offers. Even at $79, this is a very powerful and capable filter.


One of the best things about faucet filters is the compatibility that comes with them. The freedom of fitting this filter on any sink of your home is fantastic and that we think is definitely a benefit of the Regenerate. The build quality and looks are added to that, making it perfect for any sink, kitchen, or bathroom.

Easy Installation and Filter Change

 Installing this filter requires minimal work and any need for professional tools. Anyone with some level of plumbing knowledge can easily fit this filter. The same goes for changing the filters. The entire mechanism is simple, easy, and quick.

What We Did Not Like?

This section is going to be a small one, and that’s mostly because of the price of this filter. There are some compromises, but that’s more of a trade-off than a con. So here are the things that we did not like about the Regenerate.

Some Faucet Incompatibility

Even though we did not face any incompatibility issues, we saw many reviews where people complained that the filter just would not fit. It can be an issue for you, but since the filter comes with a 60-days money-back guarantee, you can always return and get the full refund.

Unclear Warranty Information

Even after scouring the website for warranty information, we could not find a specific page that states the warranty of the Regenerate. It can be very frustrating for many buyers who want to be insured before they invest.

Plastic Quality

While we love the metal body quality of the filter, the plastic components of the filter leave a lot to be desired. They felt very fragile to the touch, and we cannot be sure about their longevity.

The pros of the Regenerate outweigh the minor cons, hence making it one of the best faucet water filters for its price. To buy the filter or to know more about it, click here to visit their official website.

2. Home Master MINI Catalytic Carbon Black Sink Top

Home Master MINI Catalytic Carbon Black Sink Top
View Latest Price

Another very strong contender in the sink top filter is the Home Master Mini. One look at the filter, and you’ll understand where the company has made compromises and where the company has aimed to give you the most benefits. Home Master took the concept of sink top filter and stripped it down to the basics. They are keeping everything that is functional and then not caring about the looks at all.

We ordered one for ourselves and put it through extensive testing, learning all the little details about this product. At first, we weren’t so sure, but with the continued usage, we were surprised and delighted at the same time. So here’s a brief review of the Home Master Mini sink top filter, along with the pros and cons and our verdict.

Unboxing, Looks, and Build Quality

The package arrived a few days earlier than expected, but we were a bit disappointed even though we got it before expected. It was mostly because of the packaging quality. The box that the filter came in was not in the best shape or quality. It looked like something shipped from AliExpress. The packing was good, with a lot of tapes. But packaging is not a big factor; what matters is the thing inside.

Unfortunately, we were not impressed with the build quality or the looks of the product. It is perhaps the ugliest-looking sink top filter on this list. It is a single catalytic carbon filter unit placed in a plastic housing and some hoses. It looks like something you’ll find inside a filter, as it completely misses any metal housing. So if looks matter to you, especially since this is a sink top filter, this won’t be a great choice for you.

There are no complaints about the quality of the product. Even though the Home Master is not a looker, it feels sturdy and dense for its price. The plastic feels strong and premium. It just goes to show that Home Master focused on functionality and quality rather than looking to shave off cost. Now let’s come to the most important bit- the filtration.


Right off the bat, this filter is not meant for heavy-duty filtration. The Home Master Mini can only remove a selection of contaminants from the water and misses out on some hazardous and important pollutants. So if your home’s water supply is already very poor, then you should consider an under-sink filter or even a reverse osmosis unit.

The Home Master Mini is meant for removing the dissolved chemical contaminants, along with some finer sedimentary contaminants such as microplastics, sand, dirt, debris, etc. This filter is mainly to remove chlorine (which is the main chemical contaminant in US water supply) and others such as chloramine, volatile organic compounds, pesticides, herbicides, THMS (chloroform, bromodichloromethane, bromoform), etc.

The HM Mini cannot filter out heavy metals such as lead, arsenic, mercury, etc., and minerals such as calcium and magnesium. So this is the disappointing part of this filter. But we’ll give it a pass. However, no claim should go untested. So we began testing this filter.

Testing the Filter

Since no heavy metal filtration was available in the Home Master, our test sample was spiked only with chlorine, chloramine, VOCs, pesticides, herbicides, etc. We kept the quantity of the contaminants low and began the testing.

After a few minutes of working, the sample was out. We tested the sample, and we are glad to say that the Home Master Mini is excellent at removing chlorine. There was no smell in the sample, and after testing the water, the filter removed 99% of the chlorine. The same was true for the rest of the contaminants. The pesticides and insecticides that we added were totally removed. In conclusion, the filter is meant for only removing a select group of contaminants, but it does it very well. A simple yet powerful filtration is all you want; the Home Master Mini won’t disappoint you at the lowest cost possible.

What We Loved About The Filter?

Home Master MINI Catalytic Carbon Black Sink Top user reviwe

A few things made us put this filter, and even though the list is short, these things are actually very important. So here are the pros of the Home Master Mini sink top filter.


The most compelling reason why anyone would consider getting this filter is the price. It is cheap, and by cheap, we do not mean “not worth the price.” At the time of writing this article, the filter is priced at just $55. That’s almost $30 less than the Regenerate. Granted that it is not as powerful as the other filters on this list, if you want a basic filter for improving the taste and smell of water, then this is the perfect choice for you.

Filter Life

Something that is priced so low would automatically make you believe that the company must have made compromises somewhere. Gladly those compromises are made in the aesthetics. The Home Master Mini comes with a one-year or 1,500 gallons filtration capacity, making it one of the best filters in terms of price to filter life ratio. Better yet, after one year, filter replacements cost just $20, making it the perfect “budget-friendly” choice.


Setting up the Home Master Mini is a piece of cake. No professional tools, no plumbers, just you and some skills with basic tools. You get a set of faucet adapters that fit your sink faucet’s mouth and two hoses for the filter inlet and outlet. That’s it. Easy to install


The Home Master Mini is truly mini. Standing at only around eight inches, this filter is one of the most portable sink top filters on the market. Use it anywhere since fitting it requires minimal work. The Home Master is truly a portable, simple sink top filter.

That ends the list of pros of this filter. Now let’s come to its cons, and there are a few powerful ones here.

Home Master MINI Catalytic Carbon Black Sink Top reviwe

What We Did Not Like?


This is not a powerful filter. We could have let a lack of dust or sand filter pass, but the heavy metal filter’s absence is something we cannot ignore. This filter can only remove chlorine, VOCs, other organic compounds, and sediments. But many studies have found the presence of a lot of heavy metals in the water supply. So perhaps a great option for a bathroom water filter, but using it as a drinking and cooking water filter makes no sense.

Poor Warranty

We are not at all impressed by the warranty this filter provides. The parts come with a three-year limited warranty, whereas the filtration unit comes with a poor one-year only. It is seriously disappointing, and we were not expecting this from Home Master. We’ve been impressed by the other products this company makes. But the warranty for the Mini is a miss.


Looks don’t matter that much, only if it were an under-sink water filter. But it is actually the opposite. This one is meant to be looked at all the time, and it is not a looker. The exposed plastic look just makes it feel unfinished and truly an eye-sore. Your perfect kitchen look will be destroyed with this one, so think of ways to cover it if you plan to get it.


Since now you know what this filter is capable of, or more aptly, what it’s not capable of, the potential buyers for the Home Master Mini are a very narrow group of people who are looking for a cheap water taste enhancer by removing chlorine and dirt. On the other hand, if you are looking for heavy metal removal options, the Mini Model Plus would be the right choice. It is, in fact, priced lesser than this one but has a lower filtration capacity.

3. Waterdrop Faucet Water Filter

View Latest Price

Every list has a star of the show, “crème de la crème,” or simply, the best of the best. The Waterdrop Faucet water filter is certainly that. Waterdrop is a brand that we have loved for a long time, not just because they make great filters, but the innovation in design and functionality they bring with each product. For this faucet water filter, the company looked at all the different faucet filters in the market, noted the missing features, and then made the perfect faucet filter.

We tested the filter, looked at everything great and not so great about it, and here’s what we found. It is a brief review of the Waterdrop Faucet water filter, along with our verdict on whether you should get it or not. Let’s begin with the initial impressions.

Unboxing, Looks, and Build Quality

With a tiny bit of shipment hassle (from UPS, of course), we got the package with the filter. Removing the cardboard box, the box in which the filter came was delightful to look at. Holding and opening the box will make you feel happy to have invested in this filter. And once you take a look at the filter in real life, you’ll be even happier.

The filter looks very similar to the Regenerate, but perhaps it is due to the symmetry in design or dimensions; it looks better than the Regenerate by a lot. The brushed aluminum finish and the smudge-resistant coating add to the premium-ness. The stainless steel housing for the filtration unit and the faucet look great.

The same goes for the build quality. The filter is built brilliantly and feels solid. There is a good heft to it, and nothing feels hollow or thin. The pipes, knobs, housing, everything is well-built. In short, you will not be disappointed by the build quality or the looks of this filter. But our series of getting impressed by this filter is not over yet. So let’s come to the most important bit; filtration.


You would not believe it because we could not believe it! In that small cylindrical tube sits an outstanding five-stage filtration system! Yes, you read that right. Somehow Waterdrop has managed to fit in a powerful five-stage water filter system in such a small space. Even if the filtration was not that great, this is impressive.

The first stage is an activated carbon block filter which is a great choice (since granular carbon is not that efficient). The first stage offers brilliant filtration, removing most of the chemical and metal contaminants such as chlorine, chloramine, lead, mercury, arsenic, VOCs, pesticides, herbicides, etc. Along with these, the filter can also reduce the number of bacteria and other microbes, which is a nice addition.

The second filtration stage has a KDF bed which is mostly used to remove live microorganisms and some amount of heavy metals and other contaminants that may have passed the first stage. KDF beds are very strong infiltration, and it is very assuring to see this being used in the filter.

The third filtration stage is a unique one. Instead of using a micron filter, Waterdrop has used a polyester filter to remove the larger sedimentary contaminants such as sand, silt, clay, etc. This stage is a basic sifting filtration section.

The fourth stage is less of a filter and more of a remineralization section that adds minerals to the filtered water. From what we have tested and seen, these remineralization sections barely do anything, and the amount of minerals they add hardly makes any difference. But it is always better to have a feature than not.

The fifth and final section is a PP filter that stands for polypropylene membrane and mostly works on the leftover chemical contaminants such as chlorine, fluoride, and hydrogen sulfide. Again, this is something very new that we see in a sink top filter, and we were very excited to see if it does make any difference or just sit there as a gimmick.

The filter is capable of removing 99% of chlorine, lead, and arsenic. It can also remove most of the common heavy metals and chemical contaminants such as chloramine, fluoride, mercury, VOCs, THM, etc. However, since it comes with a five-stage filtration system, and the claims are huge, we needed to give it a proper and tough test. And so, with the aim to test it as extensively as we can, we prepared the test sample. 


The water sample we prepared was ready, and we had spiked it with an ungodly amount of lead, chlorine, arsenic, fluoride, and some fatal amount of pesticide. The water sample was impossible to smell and very possible to kill someone if they had a sip. We did not focus much on TDS as that is the domain of reverse osmosis filters. After everything was set, we began the filtration.

After a few minutes of waiting, buzzing, and whirring, the sample was out. The first thing we noticed was how clean the sample looked. All the dust and debris that we had put so generously could not see the light of day after the filtration. The second thing was the smell. The awful smell of swimming pool water was completely gone.

We tested the water sample, and we are glad to say that the filter did not disappoint us in anything. Lead and chlorine were completely gone, and there was no trace of herbicides or other organic compounds. So we are very sure that the water sample was consumable after the filtration. But something in us led us not to try it.

In conclusion, the Waterdrop Faucet is an excellent filter, and the presence of a five-stage filter certainly makes it one of the best, if not the best, faucet water filters. It manages heavy metals, chemicals, and even microbes easily, and with the amounts of contaminants it filters, there is no doubt that it can easily handle the normal amounts of contaminants found in the water supply—ten on ten in terms of filtration.

Again, the series of getting impressed is not over yet. Other than great filtration, so many great things put the Waterdrop filter on top. Take a look at the pros and cons of this filter.

What We Loved?

More than Filtration

While basic filtration is expected from any faucet filter, the Waterdrop faucet filter surprises you by giving more than that. Other than the general contaminants, this filter also removes bacteria and other microbes, hydrogen sulfide to some extent (HS filters are very expensive), and not just that. Still, it also adds minerals to the water. All of that for such a low price makes it just the best.

Great Filtration Capacity

The company claims that this faucet filter can manage an astonishing 8,000 gallons of water. Of course, this depends on the type of water that goes in, but even then, anything above 5,000 gallons of water comes under the “impressive” list.


This will be a shocker for many. After all the great things that you read about this filter, you might be expecting the price to be on the cons list. Well, you’d be surprised to know that the Waterdrop Faucet water filter costs just $80. Yup, you read that right; for just $80, you get a five-stage filtration system, stainless steel body, and 8,000 gallons of filtration capacity. It puts the average cost at 10 cents per day. There’s a reason why we called this filter the best in this list.

Water Switcher

Waterdrop never fails to surprise us. One of the unique features we say of this filter is the water switcher. Nobody wants to waste filtered water to wash their hands or for other unimportant uses. For that reason, this faucet water filter comes with a knob to switch the flow of water. You can choose to get filtered water or just tap water. It further extends the filter life and saves you money.

Money-Back Guarantee

The filter comes with a 30-days money-back guarantee which further ensures your money. Use it for 30 days and if you feel that this filter is not up to your expectations, then return it in a hassle-free process. While you can get the money back, we are very certain that it won’t come to that. Plus, it comes with free shipping, so you won’t have to bear the shipping cost in case of a return.

Customer support

 One of our biggest gripes with faucet water filters has been the lack of real-time support. There are cases when people cannot figure out things or face faucet compatibility issues. That is when they need to have someone to talk to. Gladly, with Waterdrop, you get a 24/7 support team to help you in case of any issues. We got in touch with one of their representatives, and the connection time was fast with little to no waiting period. It was a pleasant experience as well.

Materials Used

The body is made of 304 stainless steel, which is food-grade, and all the plastic components used are BPA and lead-free. Thus, ensuring the safety of your health. The box comes with all the essential things you need to install it and a wrench and faucet adapter.

Waterdrop Faucet Water Filter reviwe

What We Did Not Like?

Honestly speaking, there was nothing that we did not like about this filter. At this price range, it does more than any other filters can do. But for its sake, there might be a slight compatibility issue if the faucet’s mouth is less than 0.59 inches, or if it has an interior aerator, and any irregular-sized faucet.


The Waterdrop faucet filter is an excellent faucet filter and the best one on this list. It excels in every parameter that we use to test filters. With a price tag of $80, no other faucet filter can come close to the versatility or filtration of the Waterdrop faucet water filter. We are recommending this product without a doubt.

4. Waterdrop Faucet Water Filter for Kitchen

Waterdrop Faucet Water Filter for Kitchen
View Latest Price

We loved the previous Waterdrop product so much that we decided to include another product from them. They need to work on the naming process. To make it less confusing, we’ll refer to this product as a kitchen faucet filter. This filter is slightly different from the one before. The KFF is focused on removing mainly chlorine from the kitchen water supply and improving the smell and taste of water. With this in mind, Waterdrop has designed this filter in such a way that using it for cooking purposes becomes a breeze. 

So we ordered one to test it properly and give you the review for it. Here’s a brief review of the Waterdrop kitchen faucet filter and our verdict on whether this is the right choice for your kitchen or not. Let’s get started with the first impressions.

Unboxing, Looks, and Build Quality

The packaging has never disappointed us when it comes to Waterdrop, and this time it was the same with this filter. It came in a well-packed box with the proper amount of taping. In addition, the filter was padded properly to prevent any transit damage. You’ll not be disappointed during the unboxing experience.

The same can be said for the looks. The filter is made of food-grade 304 stainless steel with a brushed metal finish and an anti-smudge coating. It not only makes the filter look very premium but also prevents those ugly marks that come from touches. We like the stout and short design. Many of us found this filter to look like a ketchup dispenser, but that adds to its charm.

The build quality is also solid. The structure feels well-built, and there is no sign of wobbling in the walls of the filter. The swivel mechanism is also very smooth. Everything about this filter feels premium, sturdy, and durable. We’ll give it top marks for the look and build quality. It certainly feels more expensive than it is. And now, let’s come to the most important feature of this filter, the filtration. 


This filter is not a complete water filter. That is what makes it different from the previous filter. The kitchen faucet filter is geared towards making the taste and smell of the water better. Most of the water supply in the US has an excess of chlorine, which gives it that awful smell and test. So we did not expect too much. As with almost all the filters, it uses a single catalytic Sri Lankan coconut shell carbon block for the main filtration. The filter is capable of removing 99% of the chlorine from the water along with some other chemical contaminants.

There is also a filtration membrane that’s included so it can remove some larger contaminants, such as dirt, sand, etc., up to a certain extent. While not mentioned on the product page, we’ll test the filter to see how effective it is against organic contaminants and other chemical contaminants. But for the readers, this is just a chlorine filter with some additional benefits. So to test the efficacy of the filter, we prepared our water sample.

Testing the Filter

Our water test sample was ready. We added an excessive amount of chlorine, reaching a level of 18 parts per million. For reference, the CDC says that safe chlorine levels are under four parts per million. We added a little debris, some VOCs, and a dash of herbicide along with chlorine. With the sample ready, the filtration commenced.

After a few minutes of waiting, the water sample was out, and we were not disappointed. The Waterdrop kitchen faucet is an excellent chlorine filter because the sample, which was once difficult to bring close to the face, was now showing no trace of chlorine. Testing the sample revealed that the chlorine level was 3.5 parts per million. It is beyond impressive and just shows how great of a chlorine filter it is.

And coming to the other contaminants, the filter managed to remove the larger contaminants completely; thanks to the filtration membrane. The same was the case for VOCs. It had no problem removing the organic compounds. However, the filter performed poorly in removing the herbicide, which was kind of expected as it was a very strong contaminant, and the filter is not meant to handle such chemicals.

In conclusion, the filter will easily manage high amounts of chlorine and other chemical contaminants. If you’re looking for a basic filter to improve the taste and smell of the water, then this filter would be great for you. It does excellently what it claims.

There are some other great things about this filter that will add to the reasons why you should get the filter. At the same time, there are some cons of this product that will refrain you from getting this filter. Let’s look at the things we liked about this filter and things that we did not like.

What We Liked?

 Waterdrop Faucet Water Filter for Kitchen user reviwe

The Design

 This is one of the most stand-out features of this filter. Waterdrop has designed it very radically with this 360-degree swivel design. You may not like it, but there is no denying that it looks very different and could be a conversation starter with your cooking buddies. We liked the design and their idea of giving something different in a world of basic faucet water filters.


Another great thing about this filter is the price. You can get this filter for just $48—a great chlorine filter system with a solid build and design at under $50 bucks. Yes, there are many other chlorine filters in the market that are priced lower than this, but they lack the build quality and other features that the Waterdrop faucet filter gets.

Money-back Guarantee

The filter comes with an excellent 30-days money-back guarantee, which ensures that even if you don’t like the product or are not satisfied with it, you can get all your money back. It makes it even better as you can get it, try it for yourself, and see if it fits your needs or not.


The filter comes with an easy switch that can switch the water source, allowing you to use the tap water or the filtered water whenever you want. It prevents wastage of filtered water and prolongs the filter life. The filter also offers a flow rate of 0.5 GPM, which lets you fill a cup of water in 6 seconds. You also get a 24/7 customer support service in case you need any help. All these little things make using the filter very convenient.

Waterdrop Faucet Water Filter for Kitchen reviwe

What We Did Not Like?


We know that this is just a chlorine filter, but it could have been a bit more. If only Waterdrop could have added heavy metal filtration in it, this would have taken the lead in the chlorine filter section. We are always looking for that perfect filter that can manage all the contaminants, and it could have been that. But sadly, that’s not the case.

Filtration Capacity

This is the most disappointing part about the Waterdrop Kitchen Faucet filter. The filtration capacity here is just 320 gallons, which would hardly last for just 3-months. We know that due to the size and price, the filter life was going to take a toll, but we have seen smaller and cheaper chlorine filters that come with at least 6-months of filter life, some with 1,500 gallons of filtration capacity.


Waterdrop kitchen chlorine filter is a great choice if you are looking for a filter with excellent build quality, looks, and other features such as customer support. This filter is for people who want to get something that stands out. With its eccentric yet useful design, this is perhaps the most unique kitchen faucet water filter on the market. So if you can manage to ignore the short filter and can take the hassle of changing the filter every 2-3 months, then go for it. If you can’t, then skip this one.

5. PUR PLUS Faucet Filtration System with Bluetooth

PUR PLUS Faucet Filtration System with Bluetooth
View Latest Price

If you think you have seen the most bizarre, unique faucet water filtration system, and it is not the PUR plus faucet water filter, you’re wrong. We hardly have the right words to describe this filter, but it certainly is a conversation started. Better yet, this filter can also double down as a party trick. The Pur Plus hardly looks like a filter and is more like a spy device that you’d put to scan the water condition. 

We ordered one for testing it and what’s funny is that most of the time, we were perplexed as to who came up with the design of this filter. Taking compactness to the extremes, here is the review of the Pur plus faucet water filter system along with its pros, cons, and our verdict on whether you should get this filter or let it “pass.” Let’s start with the first impressions.

Unboxing, Looks, and Build Quality

We were surprised at the size of the box when it was delivered to us. We know that this filter is small, but once you get it in your hands, you realize the compactness of this filter. The box that the filter came in could have been a little better. It felt a little thin and light, but the padding and packaging were done nicely to prevent any transit damage.

The looks of this filter are perhaps the most polarizing thing, and it divided the people here. Some love it; some hate it. But there’s something very futuristic about it. I loved the design as it looks unique and something apart from the crowd.

Coming to the build quality, this wasn’t polarizing at all. The Pur Plus feels sturdy and solid. There’s denseness to this filter which makes it feel very premium. The lever, buttons, and texture feel well-built. We are very impressed with the quality of the filter. Now let’s come to the most important bit, which concerns us a little, owing to the small size of the filter.


Despite being small and compact, the Pur Plus is a capable filter. So capable that it is bound to surprise you. The filter is certified to remove 70 different types of contaminants, including heavy metals such as lead and mercury. In addition, this filter can remove chlorine, benzene, DEET (insecticide), herbicides, pesticides, pharmaceuticals, and more.

Covering lead, mercury, and chlorine covers most of the common and dangerous contaminants. But the additional protection from pharmaceuticals, herbicides, pesticides, etc., makes this filter even better. In addition, the filter uses activated carbon and is designed very cleverly to accommodate the filter and the technology as well. But we had to test the filter to know if it could really do what it claims.

Testing the Filter

Extraordinary claims need extraordinary results. We prepared our test sample with high amounts of lead, mercury, chlorine, DEET, ibuprofen, and herbicides. The amount of these contaminants that we added was way too much than the normal levels. But for the sake of testing, we had to increase the number of contaminants. 

After a few minutes of filtration, we were ready to test the sample. We did not add any sedimentary contaminants since there is no micron filter. As a result, the sample lost the awful smell of chlorine that was there before. We could also not smell any organic contaminants or the characteristic smell of DEET.

Testing the sample showed that there was no trace of lead, chlorine, and mercury. Benzene was also removed completely, while there were trace amounts of DEET, herbicides, etc., which is to be expected since these contaminants were in high concentrations. Therefore, in trace amounts, the filter will be capable of removing it completely.

In conclusion, the filter is capable of doing what it claims. The Pur plus offers focused filtration, removing the most important and dangerous contaminants.

With great filtration and great build quality, there are a host of great things to be said about the Pur Plus. Here are all the things that we liked and did not like about the Pur plus.

What We Liked?

PUR PLUS Faucet Filtration System with Bluetooth user reviwe


The Pur Plus is truly a portable faucet water filter system. You can literally fit this filter in your pocket with dimensions of just W 6.8″ x H 2.9″ x L 5.2“. In addition, the faucet is compatible with most taps, and it can easily latch on to the tap without the use of any special tool. It makes the Pur plus truly portable.


Not only did the company manage to fit a filtration unit inside such a small body, but they also managed to fit in Bluetooth and chip to make this faucet filter a smart filter. Connect the filter using a smartphone app and get vital data about the performance of the filter. For example, the app can show the life of the filter and how long before ordering a replacement. It also tracks water usage, which is very helpful if you track your water intake. We tried using the app, and it is decent. It’s a little rough around the edges, but it does all the things it needs to do to be useful.


With the great portability and the addition of Bluetooth tech, you’d think that the price of this filter would be above the three-digit mark. Well, then you’d be wrong, and by more than half! At the time of writing this article, the Pur Plus is priced at just $47.99. That’s not even half of a hundred bucks, with Bluetooth app tracking, great filtration, portable and small in size, and high-quality build at just $48. This faucet filter is a steal. 

Filter Change Light: Don’t want to use the app? Totally fine, even though we did not find using the app to be useful. But the filter change alter is something that makes the app indispensable. However, the Pur Plus comes with a filter change light that shows either green, orange, or red, which indicates the status of the filter. It makes the filter even more desirable as this is the only filter in this list that comes with a filter change light.

Easy Installation

 Installing this filter does not require specialized tools or professional help. All you need is just basic dexterity and removing the aerator (if any). Identity the threading, and then you’re all set. It took us around seven minutes to install this filter. Changing the filter is also very simple, albeit it could be a bit tricky when doing it for the first time.

These were all the things that we absolutely loved, but that does not mean the Pur Plus is devoid of any flaws. In fact, it has some of the most impactful cons, which might make you reconsider if you are planning to get this filter. So let’s take a look at all the things that we did not like about the filter.

What We Did Not Like?

Low Filtration Capacity

 It is not a shocker that this filter comes with a poor filtration capacity. With small size comes big sacrifices, and this filter shows just that. The filter is capable of filtering only 100 gallons of water. It is abysmally low. The company claims that 100 gallons would last for three months, but we seriously doubt that. One hundred gallons just makes this filter unusable unless you live alone. So for that reason, this becomes one of the biggest cons of this product.

Water Flow Rate

 We were not impressed by this filter’s water flow rate. Filling up a water bottle feels like an eternity. The flow is uniform and laminar, but it is just too slow, so slow that it becomes frustrating. So if the poor water flow rate is something that bothers you, then steer clear of this filter.

Shipping Kerfuffle: Here’s a problem that you’ll find very frustrating. The filter is priced at $48. But the company does not provide free shipping for orders below $50. So for standard delivery, you’ll have to pay an extra $5, which increases the price to $50. So we’d suggest that you better order the filter along with the replacement filter. It would prevent the extra $5, and you’ll also get the extra filter which you’d need very soon.

No Money-Back Guarantee

We looked through the website and scoured everywhere but could not find it. There is no money-back guarantee that comes with this filter. There might be a return policy where the company might give you a replacement filter, but there is none for the money-back guarantee.

Bluetooth Gimmick

 We have tested many water filters, both over the counter and under the sink, even whole house water filters. We find any filter that comes with an app and the option to show stats of how much water has been used, etc., we find to be a little gimmicky. Apart from a filter change alert or filter life countdown, there is no genuine use of the app. Companies usually charge extra for this “smart” feature. But we’d prefer to have better filtration than an extra app you need to log in to. 


The Pur Plus Bluetooth water filter is definitely an eye-catching and unique faucet water filter. And where we thought it would lack, it didn’t; the filtration. This small filter is capable of removing some of the most toxic and dangerous contaminants. With great filtration, portability, and design, this filter could be the perfect choice for you. But, only if you live alone or intend to use this filter for minor uses because of the insufficient filtration capacity. If you are into tracking your water intake and getting data about filtration, then the app would also be helpful. That’s all about the Pur plus, a great, portable, and small filter that definitely would start a conversation.
