Hygiene is no more important that it is today with the state the world is in. And one of the most important things that needs to be hygienic is the water we drink. How can we make sure that we drink safe water? We drink from the tap, right? And do you know what filters tap water?

Right, water filters, of course. Or water purifiers. There’s some difference between the two, which we will discuss later on.
Anyway, one of the cheapest types of water filters out there is the faucet water filter. Just because it is cheap, though, doesn’t mean that you should look down on them. It is ideal for low volume water filtration, and has many more advantages as well.
We will discuss these many more advantages as well as everything you need to know about the faucet filter below. First of all, we start with the review of the 5 best faucet water filters on the market today.

5 Best Faucet Water Filters In 2020
1. PUR FM-3700 Advanced Faucet Water Filter, Chrome
When we began researching for this review, we found one similar statement in most websites: “Most faucet water filters operate the same way”. This is not surprising since faucet water filters are a specific category of water filters, and it is not that all water filters are the same – just that all FAUCET water filters are the same, right?
Wrong. The PUR brand has had over 30 years of domination on the water filtration market, and this product of theirs is arguably the best faucet water filter. It comes with the promise and certification of removing 99% of lead and above 70 contaminants in water.
Yes, there is lead amount in water, and chlorine, and hundreds of contaminants. Unfortunately, water filters don’t get rid of the majority of contaminants such as water purifiers. But the removal of 70 contaminants is as much as you can get from any other faucet water filter. And among these 70 will be the most harmful microbes which make the water smelly and unfit for drinking. In short, you won’t have to worry about hygiene if you use this advanced faucet filtration system.
Did you know that faucet water filters can readily switch between filtered and unfiltered water with the click of a switch or the swinging of a handle? You can do that with this faucet water filter as well with its simple one click tool free attachment. What’s more, it scores more points in usability since it requires no additional tools, being a cinch to install. The product has a 2 year Warranty to boot.
The faucet filter could be larger, however. This product comes with a 100 gallon faucet filter, and according to the Amazon description, this means you can get 2 to 3 months out of it before getting a replacement. However, we have reviewed that a 100 gallon filter will only last about a month. Of course, that will depend on how much you use the filter. Just so you know, there are bigger faucet filters out there with capacities of 200 and 300 gallons. So if want to avoid the hassle of replacing filters so soon, then think of those options.

2. Culligan FM-25 Faucet Mount Filter with Advanced Water Filtration, Chrome Finish
There are many things we were impressed with when reviewing this faucet water filter. We want to first talk about the feature this product has which the previous reviewed product didn’t: a large faucet filter with 200 gallon capacity. Of course, with double the size of the filter, the price is supposed to be higher, but actually this faucet water filter is very cost-effective. Surprised? Not more than us.
Moreover, this product is certified as well. NSF International to NSF/ANSI Standard 42 and 53 deemed this faucet water filter to filter away harmful contaminant such as the likes of lead, chlorine, bad odor and taste.
Speaking of mechanism, this faucet water filter makes use of 0.5 gpm (gallons per minute) flow and 60 psi (pounds per square inch). What these numbers mean is that this is quite a strong faucet water filter, definitely worth its price.
The Amazon description says that there is no hassle in installation, and that no other tools are required. We do agree that virtually all faucet water filters come with easy installation. However, there have been customer complaints surrounding replacement of the faucet filters.
Furthermore, this product comes with a convenient switch between filtered and tap water. All you have to do is to use a diverter tab. Finally, the product has a 2 year Warranty.

3. DuPont WFFM100XCH Premier Faucet Mount Drinking Water Filter, Chrome
The buying appeal of this product is its in-built Micro ban Antimicrobial product protection which provides extra protection against bacteria. What you must realise is that water filters don’t discard of all bacteria and virus. If you are worried about that, then plan on buying a water purifier which eliminates above 80% of microbes in water.
If you want to stick to faucet water filters though, which are far more economical and easy to store, then this product will give you the utmost protection from microbes. Not just bacteria, the faucet water filter also filters out lead, chlorine, cysts, sediment, linden, benzene, asbestos, and mercury. This essentially means that you get filtered water which is tastier to drink, and safer and more hygienic too.
Unfortunately, the filter is small, with a capacity of 100 gallons. The performance of the faucet water filter, though, is nothing to scoff at: it has an impressive speed of 0.5 gpm. To cap it off, the product comes with a Warranty of 3 years, which is 1 year more than the other ones. Thus, overall, we think this is a very solid faucet water filter.

4. Engdenton Faucet Water Filter Stainless-Steel
We had a hard time on choosing between this and our number one faucet water filter. This monster of a faucet water filter boasts High-quality food grade 304 stainless steel housing, which basically means that it is leak-proof and Cracking-proof, highly durable and a long lasting product.
Not only is its exterior a beast, its functionalities are sky-high as well. First of all, it is equipped with a 320 gallon filter! 320? That’s more than thrice the capacity of our top recommendation. That means that at the very least, you won’t need a filter replacement within 3 months of usage. It also has high speed of water flow, with 0.5 gpm. And it’s easy to install as well, requiring no additional tools.
Another aspect of this faucet water filter which makes us score it high has to do with its usability. It can be rotated 360 degrees. Do you know what this means? It means you can just suit the angle so that you can just lean in forward and then have the falling water in your mouth. Yes, haha, we tried it. A more serious way to use it would be to position the angle so that you can wash your hands and elbows without having to strain yourself.
Equipped with the most advanced Activated Carbon Fiber (ACF) filtration technology, the efficacy of this product in filtering contaminants is sky high. For example, it will do away with lead, chlorine, sand, rust, and cut away bacterial growth with ease. However, it won’t increase the TDS of the water, something which water purifiers do.
One major flaw of this faucet water filter is that it is not universally compatible. It won’t fit all faucets, and to us, that’s a big no-no. Do check whether you have a faucet it is compatible with if you plan to buy it.

5. Kabter Faucet Mount Water Filter System Tap Water Filtration Purifier,Chrome
Built to last with ABS plastic, this faucet water filter is quite easy to use along with being durable: just click a switch and instantly get pure, clean water devoid of mercury, lead, cysts, chlorine.
The two things we were really impressed with, and which earned this product’s place on this list, are compatibility and filter capacity. The faucet water filter is compatible with most faucets, and has a filter capacity of 200 gallons. These two things are among the top things to consider when buying the best faucet water filter, and trust us that this product fills these two criteria.
To be honest, this product doesn’t have premium features and cannot measure up to the others on this list. For instance, it does not have a Warranty, and is not certified by any top company. Neither does it boast any specialised functionalities such as antibacterial protection. However, this all means that it isn’t as expensive as many others on the list. Moreover, as mentioned, it fulfills the criteria of sufficient filter capacity and good compatibility, and this makes it a very solid choice.

There are plenty more amazing faucet water filters on the market. Take a look at our review of another top brand: Best iSpring Water Filter Review 2020
Why Do You Need A Faucet Water Filter?
Some of you might be wondering if faucet water filters, or water filters in general, are at all necessary for most people. Don’t most people have access to pure water from their municipal water supplies? Isn’t tap water pure enough?
Yes and no. True, the quality of tap water has increased a lot with the advancement of technology. And if you live in an area which is relatively well developed, you shouldn’t worry about your tap water that much.
Stifling Bacterial Growth
That you WOULD say before seeing the magic of a water filter. Ever wonder how tap water, which is accessible at such a large scale, is pure enough and safe to drink? A big reason for that is that chlorine is added to the water to disinfect it. Water chlorination is a very effective and convenient way to disinfect water from virus and bacteria and other microbes.
However, there will always be some level of bacteria all around us, even in our body and in the water we drink. We decrease them with water filters and purifiers, but even the most effective of water purifiers can’t eliminate 100% microbes in water. The important thing is that more than enough bacteria are eliminated to make the water safe to drink. And if you use a faucet water filter in good working condition, you can rest assured that the harmful are eliminated.
[wpsm_titlebox title=”Human bodies have trillions on bacteria, most of which are good!” style=”main”] Bacteria is thought of such a dirty word, and yet we carry around trillions of them, 100 million of them being good! The number of microorganisms in our body outnumber our body cells by 10 to 1. [/wpsm_titlebox]
One thing to remember is that not faucet water filters aren’t the best fighters against microbial growth. A water purifier does that job a whole lot better. If you want a faucet water filter capable of eliminating bacterial growth, then we recommend you opt for the DuPont WFFM100XCH Premier Faucet Mount Drinking Water Filter.
Eliminating Chlorine Amount
Leaving bacteria aside, there are many other potential harmful contaminants in water. Actually, there are many other harmful contaminants in water in general (we have cut out the word “potential”).
Let’s start off by talking about chlorine. We just said that it is an effective disinfectant, right? But chlorine in water is not good for you either. Consuming high amounts of chlorine may lead towards vomiting or even coma and death! Yes, it’s that toxic.
Let us make an analogy of tap water purification by the government and the purification of a public swimming pool. Do you know that the water in low-end public swimming pools is not replaced regularly? Doing so would require much maintenance and service cost, and so the water is just chlorinated. This disinfects the water and makes it somewhat safer. But the entire premise of swimming there with days or even weeks of sweaty water caused by strangers… isn’t this all disgusting?
Though the tap water at your home is most certainly not as polluted as water in a public swimming pool, there is still chlorine used to disinfect it. You should reduce chlorine amount by means of a faucet water filter before you drink it.
See: Home Master Water Filter Review
Eliminating Lead Amount
Do you know that excessive filtration of water can be counterproductive? Yes, 100% pure water will also be missing essential minerals that are normally present in water – minerals such as iron, calcium, potassium, zinc. Is lead among those essential minerals?
Definitely not. Consuming lead will lead to a heightened blood pressure and kidney damage. The Environment Protection Agency has deemed lead a toxic element which should be entirely eliminated in drinking water.
Many of the best faucet water filters eliminate lead amount in water. If you want the best of them, opt for the PUR FM-3700 Advanced Faucet Water Filter.
Eliminating Other Sediments
Sediments? Is that a fancy word? Sediments are basically residue, some leftover amount of dirt or sand or metal in water.
What? How can that be, you ask? You say you have never seen dirt or sand or metal in your tap water? Of course, the amount is very little, and most probably left unperceived by the naked eye. But if you were to take a microscope – no, leave that; if you were to filter the sediments out from a bucket of water, you will be surprised as to how much residue is visible.
Just fill up the bucket with water in your washroom (or wherever) and then pour it out (or use it for bathing). You will see a visible amount of leftover dust or dirt at the bottom of the bucket. Convinced?
You don’t require manually filtering it to see. A faucet water filter will do that for you and more.
Tasty Water
What more does a faucet water filter do besides eliminating contaminants? Why, it makes your water tastier. Tasty water? Isn’t water bland and tasteless? Um, you’ve got a point there, but there is such a thing as a fresh and odorless taste. Yup, we are mixing taste and smell here, as faucet water filters, by dint of eliminating toxicities in water, will take away the bad and smell of water, as well as the metallic tinge.
More Economical
Faucet water filters are pretty cheap, but you do need to replace the filter every few months. How can it then be an economical choice, you ask? That’s because when compared to buying bottled water, a faucet water filter will save you tens of thousands of INR (or more).
You might gawk at that number, not believing bottled water costs that much. Do you know why they cost so much? Research says that around 90% of the cost of bottled water goes into manufacturing and marketing, while only the remaining 10% is for the water itself. Of course, a single bottle of water doesn’t cost much at all, but when you look at long time expenditure, this is appalling indeed. Wouldn’t you rather use a faucet water filter? Doing so would relieve you of the burden and hassle to stock up on bottled water as well.
Environment-Friendly
Now, what are bottles made of? Plastic. And we all know how harmful plastic is to the environment. Plastic is a non-biodegradable material, which means it will not decompose into the earth for hundreds of years.
This is extremely bad for our planet because space is reduced due to make room for the non-decaying plastic. Plastic also releases harmful chemicals into the soil, eroding it. What’s more, you all must have heard of plastic pollution in the sea, right? About how large amounts of fish die out of eating plastic. Very pathetic indeed.
What can you do to reduce or even eliminate plastic usage in your lives and still get pure water? Why, a faucet water filter, of course!
Better Than Other Water Filters In Some Ways
Up until now, we have discussed the benefits of using water filters. But why should you use a FAUCET water filter?
Well, for one, it is a cheap alternative to large filtration systems. It doesn’t do as thorough a job as a conventional filter tank, nor a water purifier. For example, most faucet water filters do not eliminate bacterial growth. However, it gets the job done and makes your water more than pure enough to drink without worries.
Are we sure if a faucet water filter removes enough contaminants? Well, no filter or purifier will ever give you 100% pure water. So “enough” is subjective to the level of your satisfaction. But rest assured; take it from us that the best faucet water filters will take care of the harmful contaminants. So drink without worries.
Just because it is cheap does not mean it is a low-tier filtration system. In fact, it is better than other water filters in many ways such as hoarding less space. You don’t need to set aside space for the faucet water filter. It can simply fit with your faucet.
Another advantage of faucet water filters over others is that they have a switch or handle to easily switch between filtering water and not doing so. This means that you can prevent the faucet water filter from working nonstop, 24/7.
Afraid of the hassle of installing the faucet water filter? Don’t worry on that account, as all the water filters we reviewed are very easy to install. One disadvantage though of faucet water filters is that they require replacement of their filters every few months (of even less if the filter capacity is low and your family size is huge).
Types Of Faucet Water Filters
There are many types of water filters, but there are not much variety in faucet water filters. Of course, different sizes and designs exist, with different colors available. However, there are only two types of faucet water filters:
Direct Flow-Thru Faucet Filter
As the name suggests, it is directly attached to the end of the faucet. This is both advantageous and disadvantageous. It is good because it saves a lot of space, and you can put other things on your sink.
However, since the filter is directly attached to the faucet, it can’t be too big. Thus, its small surface area means the filter’s capacity will run out soon, and so will need replacement faster.
Side Offset Flow-Thru Faucet Filter
This is the most popular type of faucet filter. It sits, as the name makes evident, on the side of the sink. This means that it can be larger and have bigger capacity.
However, if it is too big, the sink may be experiencing slow but steady stress on one side (the side the filter rests on) and so may in time be tipsy and even break down. There is the additional disadvantage of the filter being more expensive; no surprise there – with bigger filter cartridges comes bigger cost.
How To Clean & Replace A Faucet Water Filter
This is the nightmare for every faucet water filter owner. It is true, faucet water filters require replacement of their filters every few months. The time frame will of course depend on how much you use it and how big the capacity is of the filter.
But don’t fret. Replacing a faucet water filter isn’t very complicated at all. Some of the best faucet water filters on the market don’t even require additional tools to be installed. It is also a good idea to clean the faucet water filter when replacing it. Maintenance while replacement: the best example of killing two birds with one stone!
There is of course an instruction manual that comes with the bought product. There will be a diagram there to demonstrate installment of the filter. Still, we are providing a step by step process of it all.
1. Turn Off The Water Supply
This is a precaution rather than a truly necessary step, because water won’t come out anyway unless the faucet is turned on. You can ignore this step if you are sure there is no leakage.
2. Remove The Aerator Of The Faucet
If your faucet doesn’t have an aerator, then skip this step. But most faucets do have a threaded aerator. It is located on the end of the faucet. We recommend you wrap a cloth around the faucet to protect it from unnecessary jerking while you use a wrench to loosen the aerator. Then spin the aerator off using your hands.
3. Clean The Threads
You know what’s next: cleaning the threaded aerator you just opened. Oh and to make sure that the threads attach after this clean-up, attach a few wraps of Teflon tape on it.
4. Determine Whether You Need An Adapter
It could be that the threaded aerator is damaged. If it’s in good shape, then skip this step. If not, then replace it with the adapter which you must have got from the filter replacement kit.
5. Install The Faucet Attachment Piece
Look at the diagram given for this one. Be careful not to attach the water filter cartridge yet. That comes next.
6. Attach The Cartridge And Other Parts
There may be some other specialised parts for you to attach. Do so along with the water filter cartridge. Isn’t it amusing that the actual replacement is the 6th (step) of the process of water filter replacement?
7. Flush The Leftover Water
Now all that remains is for you to drain out the remaining water with carbon excess. We recommend you to let the water run for 5-10 minutes. Afterwards, test the faucet water filter to see if you have installed the cartridge well. The clean-up maintenance will also do your faucet water filter well and increase its shelf life.
How Do Faucet Water Filters Work?
Don’t worry. This section isn’t written exclusively for mechanics or mechanics in training. This isn’t an advanced physics lesson. Rather, the mechanism of faucet water filters is pretty simple.
Note: We are creating two categories to explain the process, but these aren’t technically and officially what they are called. We only do this for easier explanation.
First Layer
We can divide the faucet water filter’s working mechanism into two filters. Simply imagine that there are two filtration processes.
The first is a protective screen covering the filter. Once the filter is on and the faucet is turned on, water initially passes through this external layer. It is here that the sediments, or large contaminants such as dirt and sand and rust, get trapped.
The first layer does a first screening job, if you will, leaving only smaller particles to be taken care of by the second filter.
Second Layer
This is where the a water filter gets its money’s worth from. The second layer generally comprises a thick layer of activated carbon. Carbon is activated by mixing it with other materials such as wood, nut shells, coconut husk.
The resultant activated carbon is an extremely good disinfectant, with a massive 32,000 square feet surface area to attract small contaminants! Most of the small particles get trapped in this second layer, and the filtered water is safe to drink. Keep in mind that it is the water purifier which is the superior microbe killer, but the best faucet water filters do a pretty good job as well.
Not only do contaminants get trapped in the second layer, but certain metals also get trapped. Again, a faucet water filter does not trap most metals such as magnesium and calcium. However, the best faucet water filters can eliminate lead and chlorine content very well.
Things To Consider Before Buying A Faucet Water Filter System – Buyer’s Guide
By now, you must have caught wind of the key factors by yourself while reading this post. Nonetheless, we will be discussing them below for your benefit:
Filter Capacity
One of the major hassles in using a faucet water filter is that you have to replace the filter cartridge every few months. Specifically speaking, a 100 gallon water capacity filter will last you about one month (though this of course relies on how much you and your family use it). That means you can go 2 months without filter replacement if the capacity of the filter is 200 gallons, and 3 months for 300 gallons.
Thus, we recommend that you opt for a water filter with high capacity. However, filter capacity isn’t everything. If it was, we wouldn’t have picked as our first pick a faucet water filter with 100 gallon capacity. Also keep in mind that the bigger the filter capacity, the higher the cost.
Effectiveness
Efficacy is of course a very, if not the most, significant aspect for any product in existence. Faucet water filters come with varying quality. Some can remove over 70 contaminants in water (that’s a lot) while some only remove the basest of sediments like dirt and dust and sand. If you are okay with your faucet water filter just making your water fit for drinking, then any faucet water filter on the market will do the job.
But if you are looking for the best, which is post is about, then keep in mind that faucet water filters can do much more than provide marginally drinkable water. It can also remove chlorine and lead and prevent microbial growth. We recommend only the best faucet water filters (take a look at our review of the five products for this!) for those extra benefits.
Compatibility
It is with a heavy heart that we say that not all faucet water filters will fit with all faucets. That is the main reason why a supreme product like Engdenton Faucet Water Filter Stainless-Steel is not first on our list.
The other four faucet water filters on our list are very compatible, but you should keep in mind that they don’t have universal compatibility. For instance, they won’t work with pull-out or hand-held faucets. Unless your faucet is like those, you don’t have to worry about the best faucet water filters on the market.
Durability
One of the most varying aspects that faucet water filters come with is the material they are made of. We recommend as durable a filter as you can buy. Examples of tough quality material is stainless steel and ABS plastic. The more durable the filter, the better it will age and the more longevity it will have.
Warranty
Speaking of longevity, some models give you their word on the minimum lifespan of their faucet water filters. Remember that though you have to replace filters every few months, you don’t have to replace the whole product. The best faucet water filters on our list have Warranty of 2-3 years. However, many don’t come with Warranty. So be wary of that.
Design
The style and design of a faucet water filter is very important according to us, much more so than it is for other products. In other words, normally we don’t put much stake on fancy or classy designs, but when it comes to faucet water filters, we change our mind.
Why? That’s simple. It’s because it’s a filter on attached to your faucet, or at least beside your sink. Would you be so careless as to choose a design that doesn’t fit at all with your sink and surroundings and make your faucet water filter stick out like a sore thumb? Unless you want such a contrast in style, we recommend you choose a good looking faucet water filter which matches the surroundings and yet stands out.
Swivel Capacity
In this case, capacity doesn’t have to do with volume or quantity. Rather, it is about potential. Some faucet water filters can swivel horizontally and some can do so vertically. What matters is that it has 360 degrees swivel capacity. It’s a very fancy yet useful facility – to be able to swivel the faucet water filter any direction you want.
Frequently Asked Questions (FAQs)
1. Do faucet water filters really work?
Of course they do. They work very well in removing harmful contaminants in water and making water safe, healthy, and tastier to drink.
2. What do faucet water filters remove?
All faucet water filters remove large contaminants like sediments (visible waste like sand, dust, dirt). Many of the best faucet water filters also take care of bacterial growth and metals such as chlorine and lead.
3. Should you actually filter tap water?
Tap water has become more and more hygienic with the development of technology. But we have verified that there are still many places where tap water is unfit for drinking.
Moreover, tap water mostly uses chlorine for disinfecting. And chlorine as we have discussed is not only harmful but carcinogenic. If you filter tap water, more contaminants will be dealt with than when you don’t.
4. Are faucet water filters better than water pitchers?
Both faucet water filters and pitcher filters are cheap but effective enough water filters. If you compare between the two, faucet water filters are of higher quality. They have a longer shelf life, generally remove higher amounts of contaminants, and may also take care of other things such as antimicrobial protection and (some) metal removal.
5. What matters the most when buying a faucet water filter?
Look at the Buying Guide for an elaborate answer for this. If we were to pick one factor, we would go with filter capacity.
6. What are the best benefits of faucet water filters?
There are many a benefit to using a faucet water filter. We feel the best of them are:
It is economical.
It is environment-friendly.
It makes water safe, healthy, tastier for drinking.
7. Should I buy a big faucet water filter?
Yes, the bigger the filter, the more capacity in gallons will it have, and the longer you can put off having to replace it. Do keep in mind though that the bigger the filter, the more will be the price obviously.
8. Do I need any additional tools when installing or replacing the faucet water filter?
As we have pointed out, the best faucet water filters require no additional tools for installment and replacement. All you need will come with the product in the tool kit. However, you may need a wrench to loosen the threaded aerator if you can’t unscrew it with your hand.
9. Is it true that faucet water filters make water tastier?
Yes, a faucet water filter removes many contaminants from water which makes it taste fresh and odorless.
10. Which type of faucet water filter is best between Direct Flow-Thru Faucet Water Filter or Side Offset Flow-Thru Faucet Water Filter?
Both have their share of advantages and disadvantages.
The Direct Flow-Thru Faucet Water Filter:
Advantages: cheaper; takes less space
Disadvantages: smaller water filter cartridge
The Side Offset Flow-Thru Faucet Water Filter:
Advantages: larger water filter cartridge
Disadvantages: more expensive; exudes constant heavy load on the side of the sink on which it rests upon
A Final Word – Personal Recommendation
Faucet water filters are, according to us, the most convenient type of water filter there is. They are cheap, require less space, and provide more than satisfactory service.
We hope that with the Buying Guide, detailed faucet water filter discussion, and the review of the five best faucet water filters on the market today, you have the same appreciation for faucet water filters as ourselves.
But in case you are still undecided about exactly which product to buy, then might we suggest a personal recommendation?
Our personal recommendation is this one:
The single most effective and powerful faucet filter today, it can get eliminate over 70 contaminants and remove 99% lead in water. What’s more, it is very compatible and has a 2 year Warranty.
The Engdenton Faucet Water Filter Stainless-Steel is a strong runner-up. The reason why it did not come first place is because it scores low on compatibility. On the other hand, our top recommendation is compatible with most faucets, and also functions no less brilliantly as the runner-up. If your faucet is a match with Engdenton though, then you may choose that.
I like you use water every day in everything I do. I love to find better ways to filter water I drink, soften hard water and find amazing water bottles for when I’m on the go.
I want to share what I find with you and review the options you might be looking for.
