The Top 9 Best Faucet Mounted Water Filter Reviews



Tap water has been available to the general public for what seems like forever now - at least in the US. With the advancements in our water systems, we've all pretty much felt that tap water has been considered fairly safe to drink until hearing horror stories about various crises (e.g. the aging infrastructure and other situations that we've mentioned).

Studies have shown that various contaminants were found in water systems in some locations, and of course we can't ever forget what happened in Flint, MI. There has also been growing suspicions about the quality of water over the years in other locations.

With reports and suspicions arising about contaminants from sediments to other toxins found in our tap water, it's imperative to ensure that all of us are drinking purified water. That's where water filters come into play. 

Industry experts have worked hard in tackling the issue of ensuring that we can open our taps and drink and cook with what comes out of them with the confidence that  our supply is clean and safe. Part of the problem, of course, is that oftentimes the taste and appearance leaves something to be desired.

And in other cases, as much as our municipal supplies and wells are far better than those in countries and regions that are still struggling with contaminants, there is still room for improvement.

For those of us who would simply like to take that extra step to ensure higher quality drinking and cooking water, a faucet mounted filter may be just the thing!

Waterdrop 320-Gallon Faucet Filtration System

Waterdrop 320-Gallon Long-Lasting Water Faucet Filtration System

The Waterdrop's claims are mighty indeed for a faucet mounted model (e.g. "removing" fluoride in one statement and "reducing" it in another), but they don’t explain exactly how they are able to do this other than talking about the Activated Carbon Fiber (ACF) material used in the filter. They state that their claims are backed by bata from independent tests; however, they do not include this information.

For such an inexpensive price point, we were wondering why we haven’t heard of it. The seller (which is not the manufacturer) is getting good reviews (totally separate from product reviews, which are also quite good). 

Here are some things that stand out about the product:

  • They actually include the pdf manual for us to see right up front before you buy.
  • You should get six months of typical usage before replacement is required. Thus, you'll have great value due to it replacing 2,000 bottles of water (based on a common 16.9 oz bottle).

  • The convenient switch lever makes it easy to quickly switch from filtered water to regular tap water. This feature extends the life of the filter.
  • It is easy to install, and this system also includes various adapters.
  • You get a limited, one-year warranty against defects in workmanship and materials. It also has a 30-day money-back guarantee and worry-free shipping.

    This device fits on standard faucets. It does not fit faucets with sensors, and pull-out, spray-style faucets that spray. It does not fit pull-out, hand-held, spray-style faucets. It also doesn't fit faucets with a sensor.


  • Easy to install 
  • Great value
  • High quality filter head


  • There are some complaints about the unit leaking.
  • Some consumers believe it doesn't last as long as they had hoped.

Kabter Faucet Mount Water Filter System Tap Water Filtration Purifier

Hitting the #50 mark in the 100 top sellers on Amazon in its category, the Kabter deserves a mention.

As of this writing (June 2019) this may be a fairly new product to market having only 18 reviews (which, while excellent, only date since Oct 2018); however they appear to be a responsive seller. We did notice the relatively long lead time for Amazon which makes us think it may be shipping from China. 

Also, clicking on the seller profile in their Amazon listing, it does not appear that these folks are specialists in water filtration. Nonetheless, early reviews and seller response is encouraging.

The filter includes a "Food Grade Calcium Sulfite Ball," which is KDF-55 (which you can learn about here). With this feature, contaminants are reduced, including lead, mercury, asbestos, benzene, cysts, chlorine, and sediment.

Another thing about this device is that it comes with a sturdy convenient design. It is made from grade ABS plastic that is no-leak and durable.

We will be keeping an eye on this model, and may bring it up higher in our rankings as time goes on and we see more activity around this brand and model.


  • Easy to install
  • Easy to use
  • Attractive-looking


  • Long lead time (as of this writing)

Overall Benefits Of Faucet Water Filters

There is no question that using one of these products is a superior option over the use of purchasing water in plastic bottles. For one, there are reports that some of the plastic of some of these plastic bottles have toxic materials. There have been news reports and articles expressing this occasionally.

Secondly, bottled water companies have fewer regulations than agencies that govern tap water. Sure, there are guidelines that they must adhere to through the FDA, but the government does a little more in many cases.

According to, the federal government does not mandate bottle water companies to have safer water than tap. As a matter of fact, approximately 25 percent or more bottled water is just tap.

An even more disturbing fact is that bottled water does not have to be disinfected and filtered for the removal of pathogens. They don't even have to test for giardia and cryptosporidium viruses. The big city tap water system must do these things.

Both water types regularly test for bacteria and most synthetic organic chemicals. However, the city tests for these substances more often than bottled water organizations.

With these issues and more, the NRDC concluded that there is no guarantee that bottled water is safer or cleaner than tap water.

The bottom line is buying a top-notch water filter is the answer. Furthermore, you can also use a combination of water treatment along with a filter to ensure the utmost of purity in your water.

Nevertheless, below includes the main benefits of water filters: 

1. Better Taste and Smell

They provide better tasting and smelling drinking water by reducing chlorine and bacterial contaminants. A primary complaint about tap water is the smell/taste.

2. Cost Effective

There is no question that these are more cost efficient than bottled water, even given the price of the unit (which is very affordable when you consider the cost of more complex systems). Bottled water costs on average 500 to 1,000 times more than tap water, according to the International Journal of Environmental Research and Public Health. 

3. Eco Friendly Option

This cost doesn't even take into consideration of the price to make plastic bottles that cause more excess garbage and pollution in our landfills and eco-system.

According to The Pacific Institute, it takes approximately 17 million oil barrels annually to make the plastic bottles. Even though water bottles are recyclable, a shocking percentage of them end up in our landfills, according to National Geographic. However, filters don't have to be bought or replaced as much.

4. Possibly Better for Your Health

Drinking filtered water can help protect your body from disease and can lead to better health (think about drinking polluted or contaminated water for just a moment!). Also, filtered water provides clean, healthy water for making drinks and cooking. 

5. Less Clutter

Having bottled waters around your home (the gallon size or individual bottles) can cause your home to be cluttered. Having such clutter can be an accident or even a fire hazard.  

Maintaining Your Unit

These top 9 faucet mounted filters are the crème of the crop. However, it's already established that some of them do not last as long as others. However, as with anything you own, you can maintain your unit to get the longest use of it as possible. The following includes tips in maintaining your unit:

• Note the Replacement Date

Make sure to replace the water filter on the replacement date. Water filters become less effective as impurities build up. And thus, they will be ineffective in keeping the release of harmful bacteria or chemicals back into your water when you go beyond the replacement date. 

• Follow your manufacturer's maintenance directions

These directions can be how to properly clean your filter and the parts that come with it. It may tell you how to properly store your replacement filters, not to open your replacement filter until ready to use it, etc. It may also have troubleshooting techniques and how to properly dispose of the expired filter/cartridge. 

• Other Important Notes

1. These water filters may need to be changed from a few months to once per year, depending on the frequency of use and the size of the filter.
2. There are some water filters that is not good for running hot water.
3. There are instructions available many times stating what to do when there is a problem with your device.
4. Many of these filters come with an indicator to show when it's time to replace your filter, just in case you forget. It could be a flashing red light showing to alert you, for instance.
5. Sometimes there may be a water leak when you don't thread or install the filter correctly so take precaution. 
6. Some of these devices comes with a warranty or guarantee. 
7. You must turn off the water valves most of the time when replacing the filter. 

Installation Basics

It is fairly simple to install a faucet water filter. There is no need for a professional to install it or help you install it to your kitchen sink. The following includes general steps to install your new water filter:

1. Turn off your water supply.

This step is more than just turning off the faucet. In addition to turning the faucet off, you must turn off the cold and hot water valves that are typically underneath the sink.

2. Remove the aerator from your faucet.

This step usually includes a threaded aerator on the end of the faucet. This aerator where the water comes out of is removable. Use a cloth to wrap around the aerator and then loosen it up with a pipe wrench. Then, you can twist it off with your hand.

3. Clean the seal/threads.

After removing the aerator, you must clean the threads off which are at the end of the faucet. Also, you can add one or two pieces of Teflon tape around the threads to help seal them after attaching off the water faucet filter.

4. Use the ready parts and an adapter, if required.

You then must take out all of the parts out of the package the faucet filter came in. Lay them on a cloth on the kitchen counter next to the sink. Afterward, look at the sink faucet threads to determine if an adapter piece is required which is usually included in the faucet filter kit.

5. Install the faucet's attachment piece.

Follow the instructions that are enclosed in your faucet filter kit. Looking at the diagram on the instructions, attach each piece accordingly as instructed. Ensure to do this without the water bottle containing the attached cartridge filter.

6. Attach other faucet filter parts.

Next, you must attach the water bottle with an enclosed filter to the part just threaded on the faucet. You must also attach any other necessary part.

7. Test.

Test to ensure the water is flowing smoothly at the end of the faucet filter and to ensure there is no leaks.

And that's it. These easy steps will take you on your way to ensure you and your family can have water that is great-tasting, clean, and safe. 

Frequently Asked Questions

1. Can you run hot water through the filter?

Yes, running hot water through most filters is safe. However, depending on the filter feature and the technology, running hot water through the filter shouldn't be done as frequently for some filters, in which case, they simply won't last as long as others. For most purposes, you should just use these for cold water.

2. What contaminants will these units remove?

A range of contaminants can very effectively be removed from water filters. However, not a single water filter can remove everything from the tap water. Using different treatment methods together will work wonders with a filtering system to obtain the ultimate in purity.

Water filters work by using chemical or active filtration and physical filtration. Also, most filters combine two methods, including an active filter transitioning the contaminant in a certain way and then filtering it out of the water. 

Using these combinations with at least one other treatment method will remove nearly every foreign object from the tap water. 

5. What type of water filter should I get?

The type of water filter you should get depends on your geographic location and the problem that the water system at that location has. Once you discover the problems your location has, you should check for the water filter that targets that problem.

For instance, several customers living in Chicago complained about tasting lime in their tap water. And as a result, many of these customers were dissatisfied because they bought a filter that didn't remove the lime taste. 

Thus, it's imperative to search for the water filter that will remove the tap water problems in your area. The following includes typical problems with our water systems: 

• Common Symptoms in the community or city water

The taste and odor in community or city water are typically turbidity/hardness or chlorine. Many people don't like the addition of fluoride to their supplies, in which case we would recommend a counter-top or under-counter Reverse Osmosis, which is truly the most-proven method of removing fluoride.

• Common Symptoms for well water

The taste and odor in well water usually includes chlorine, hardness, turbidity, iron stains, green/blue stains (low Ph.), a rotten smelling odor (sulfur), etc.

Residences in city/community areas can request their local water authorities to perform a water quality analysis report. This report should illustrate considerable aspects when choosing a water filter, such as turbidity and chlorine level.

Residences with well water can test their water for contaminants. They can have a professional water testing company to test it, or they can use a DIY home water test kit. 

Whether it is well or city water, the safest process is to test your water to see what contaminant is present. That way, you can determine what filter is best to buy to remove the contaminant.


Even with today's advanced systems and technology, there are still reports of contaminants in our water supplies. The most common complaints include the taste and odor typically being turbid/hard or having chlorine. The common complaints surrounding well water include the taste and odor usually having chlorine, hardness, turbidity, iron stains, green/blue stains (low pH), a rotten smelling odor (sulfur), etc.

And oh yes, then there is the famous plastic water bottle with claims of having higher standards in purity than tap. And even though our landfills and the eco-system are compromised with innumerable, used water bottles, this is the price to pay to ensure our loved ones and us are having safe, drinking water, right?

Wrong! Many of us have been fooled to thinking we are doing such a good thing for us and our families. Yet, so many reports show that we may be doing worse than tap water by the precious people in our lives with water bottles.

Using water filters are definitely the way to go. From removing the sediments and other toxins from our tap water, we can have peace in mind knowing that our whole family is safe in consuming it in coffee, other drinks, and in cooking. 

For a simple, cost-effective and easy-to-use solution to reduce some of the most common issues, consider one of these top 9 choices - you won't go wrong with them.
