Faucet Water Filter Reviews

DuPont WFFM100XCH Premier Faucet Water Filter

Out of all of the options presented today, this filter is the least expensive. It’s high on our list because the prices low but its ability to filter water is very effective. It’s also very easy to install, can filter 100 gallons of water at capacity, and the filters themselves only need to be changed every two months or so.

Not only is it very effective, but it also can eliminate contaminants from the water right away.

What we like: the price is right. For an inexpensive water filter for your faucet, it has great water production, and it’s also very effective, and the cost is low which is also amazing. Most people think you need to spend top dollar to get an effective water filter, but this one proves that nothing could be further from the truth.

What we dislike: the instruction manual is incomplete. Teflon tape is needed to complete installation of the product and it even comes with it. Yet there is no mention of this tape in the instruction manual whatsoever. If you install it without using Teflon tape, your faucet is going to leak.

Brita On Tap Faucet Water Filter System

If your water is only mildly polluted and doesn’t contain too many contaminants, you’ll prefer this model as an excellent solution for your water filtration needs. It’s very easy to install, and you can put it right on your faucet. Better yet, the filter allows you to have filtered water and unfiltered water running out of the tap.

A big advantage of this filter is it produces solid water flow when the filter is in use, unlike many other filters that slow down the water flow. If the light is green, your filter is still in good shape. If the light turns yellow, it’s almost time to change the filter. And if the light turns red, you know that it’s time to remove the old filter and put in a new one.

It also contains a particle filter called KGF55 that can remove bacteria, mold, fungi, scale, and lime from the drinking water. This is very important and makes your water heck of a lot safer.

A big advantage of this filter is its durable, sturdy, and made very solidly. Some of the other filters of this type are very cheap, made of crappy plastic, and tend to fall apart because they are much too flimsy. On the flipside, this model is BPA free and made out of food-grade ABS plastic.

Filter longevity is a second huge advantage. The filter can clean up 200 gallons of water before being changed. So you only need to change the filter every 4 to 5 months at the most and even better, they are very quick and easy to replace.

The Inner Workings of Tap Faucet Water Filters

Before we get into the nuts and bolts of these faucet water filters, please know that this is a filter and it is not a water purifier. Many people think they are the same thing, but there are certain differences.

This type of faucet water filter is going to give you filtered water. Other systems known as the reverse osmosis system will create purified water. There is a notable difference between both options as we will explain below.

With a water purifier, the water does not need to be treated before it gets purified. You can use a water purifier on well water that hasn’t been tested, or even water that you already know is completely contaminated. The reverse osmosis system used by these water purifiers can kill 99% of the existing contaminants and completely clear the water of the wide majority of them.

On the other hand, water filters should only be used on water that was already treated. If the water has too many contaminants and hasn’t been treated before, you’re still going to have many contaminants in your filtered water because it doesn’t have the same capabilities as a water purifier.

But filtered water definitely has its purpose. The quality of the water coming out of your faucet isn’t that great, and a water filter can improve the quality by as much as 20%. So you’re definitely going to have better tasting, healthier, and less toxic water which is certainly good for you and your family.

How Do Faucet Water Filters Work?

This type of water filter typically uses a filter cartridge. This cartridge is made up of multiple components that work in unison to eliminate contaminants from your drinking water. Each model is going to have different variations on their cartridge, but for the most part, the components will be similar and basically work the same way.

  • Removing chemicals – the filtration process makes it possible to remove chemicals from drinking water. They employ activated carbon filters to get rid of chemical contaminants including chlorine, chloramine, and other chemicals. The activated carbon filter is incapable of getting rid of heavy metals, calcium, and magnesium so keep that in mind. But it will be able to filter things like nitrites, nitrates, mercury, and lead and even make the water taste and smell much better.
  • Removing sediment – typically, this is the beginning stages of the water filtration process. The cartridge will contain a nonwoven screen that it has wrapped around it to get rid of small particles like sand, dirt, debris, and rust.
  • A block of activated carbon – as you can probably tell, activated carbon is an important part of the water filtration process. Since this carbon maintains a porous surface, the nooks and crannies can pull out contaminants and remove them from the water supply through adsorption. Once the porous surface is filled up with contaminants, the filter will no longer be useful, and you’ll need to replace it at this point. Even better, occasionally they’ll add silver to the filter which is capable of killing bacteria and fungi that the carbon filter might not be able to eliminate.


The main benefits of faucet water filters include the following:

  • It’s easy to install – this might not seem true, but some people choose to avoid a whole house water filter because they think it’s going to be too difficult to install. But a faucet filter is much different, and it’s a heck of a lot easier to connect to your sink.
  • Microorganism blocker – the faucet water filter can block specific microorganisms including Cryptosporidium and Giardia. Drinking these microorganisms could seriously harm your health.
  • Eliminates foul odors and tastes – if your faucet water has weird smells coming from it when the water tastes bad, this filter can get rid of the nasty taste and make the water smell normal again too.
  • No longer need to buy plastic water bottles – not only are you going to save money by installing a faucet water filter, but you’ll also protect the environment by using less plastic water bottles that do not biodegrade.
  • Nitrate and nitrate free water – faucet filters can remove nitrites and nitrates from the water. You’ll often find these chemicals in insecticides and pesticides, and they occasionally do leak into source water.
  • Chlorine elimination – no matter which faucet filter you choose, they are all designed to remove chlorine from municipal water supplies. Drinking chlorine is not good for your health, and in the past, it has even been linked to certain diseases.
  • Heavy metals blocker – although it may not eliminate them completely, a faucet water filter can severely diminish the number of heavy metals present in your water source. Heavy metals exist in pipes, contaminated soil, and even directly in the water supply and they can find their way into your home if you do not take measures to filter them.
  • Drink healthy water – obviously, the whole point to a faucet water filter is to filter out the impurities. While not exactly a water purifier, this type of filter can remove contaminants from your drinking water or severely diminish their numbers.
  • The friendly option for the environment – faucet water filters do not require electricity, and they leave no carbon footprint. Plus, if you drink all of your water from your faucet filter, you’ll avoid using plastic bottles and plastic containers that are harmful to the environment.

Faucet Mount Water Filters Buying Guide

Not all faucet water filters were created equally. Some have better features than others, and some just aren’t as good as their competitors.

Features to Look For

  • Filter lifespan – some filters are going to last much longer than others, so the lifespan should be taken into consideration when choosing a faucet filtering system. This might not seem like a huge deal now, but you’ll be able to save money over the long run if the filter lasts five months as opposed to two months. So keep this in mind when making your choice.
  • Swiveling – certain water filters can swivel 360°. When washing the dishes, not having the ability to swivel could become a major pain in the butt and this is especially true if you’re trying to clean trays, larger pots, and big pans. The swiveling action will prevent this problem from ever happening.
  • The sensor – the wide majority of water filters for faucets are very low maintenance. But one thing to keep in mind is you regularly need to change the filters. Having the ability to know precisely when the filters need to be changed is a wonderful option. Certain brands provide a sensor to let you know exactly when your filter is ready to be changed. So if this seems important to you – and it is – you should consider buying a faucet filter that has a sensor as well.
  • More than one finish – depending on the decor of your kitchen, you may want to choose the color and finish of your water filter. Some models provide multiple finishes to choose from. This is always nice to have as an option because you can find the ideal finish to match perfectly with your existing fixtures and appliances. The right filter will fit smoothly with your current kitchen decor.


Believe it or not, it may seem nearly impossible to get specific instructions to install faucet water filters because of the different brands and manufacturers available to purchase from. But it’s quite easy to explain the installation process no matter which model you happen to buy.

Before the installation actually begins, you need to have an adjustable wrench on hand as well as Teflon tape. Without them, you will not be able to complete the installation properly, and if you leave out the Teflon tape, your water filter is going to leak.

For the most part, a wide range of existing faucet water filters already provide all of the parts needed for proper installation. But on the other hand, there are a few that do not give you all of the parts required and many even forget to add the Teflon tape, although you can find it in certain models as well.

To install your faucet water filter, please use the following instructions:

  • Remove the aerator on your faucet. It’s possible that it is screwed on quite tightly, so you need to have an adjustable wrench available to twist it off just in case you cannot do it by hand.
  • Take the aerator and place it on top of the water filter inserts inside the box. Choose the right insert that fits your faucet.
  • Next, screw the newly combined insert aerator on to the faucet.
  • Fourth, the faucet water filter can now be mounted onto the insert aerator.
  • Fifth, it’s time to insert the filter cartridge into the water filter.
  • Sixth, turn your water on. Let the water run for a minimum of 10 minutes. Afterward you can taste the water to test it out. This step lets the water filter activate.
  • Last, look at your water filter and make sure there aren’t any leaks. If you see the filter is leaking, remove it and add additional Teflon tape to stop the problem dead in its tracks.

Cleaning and Replacement

Depending on the make and model of your water filter, replacing the filter cartridge may be different than our instructions. Although, for the wide majority of water filters, it’s very easy to change the filter itself and it will only take you a matter of minutes to complete the project.

If your water filter has a filter change sensor, you should pay close attention to the indicator lights and swap out the old filter for a new one at the appropriate time. In other cases with a faucet water filter that does not have a sensor light, you may receive a reminder in the mail when it’s roughly the right time to change your filter.

If there is no sensor present, it’s up to you to keep track of when the filter should be changed. Make a point to write the date down on your calendar to know when you installed the new filter so you can change it at the appropriate time.

For the most part, your water filter will have a capacity indicator on it. Simply put, the majority of them last roughly 100 gallons, 200 gallons, and sometimes even more. But this might not mean anything if you do not know how many gallons of water you’ve used.

The average household in America drinks two gallons of water per person daily. So, a quick way to get a rough estimate is to take the number of people in your home and multiply it by two. So if two people live in your home, you’re consuming four gallons of drinking water each day. If your filter has a 200-gallon capacity, you’ll need to change it every 50 days, give or take a week or two depending on your consumption.

If your faucet water filter shows signs of limescale deposits, you should take a rag, soak it in lime or lemon juice or even vinegar, and thoroughly clean the filter off. These substances combined with water should have no trouble removing the unwanted limescale.


  • How should I get rid of the old water filters? Your old water filters are recyclable. Contact the manufacturer to get a return shipping label if you don’t already have one. But some of them will already send you the return shipping label with the filter, so keep it so you can recycle it later on.
  • How often should I change my water filter? If the filter has an indicator light, you should follow the instructions on the sensor. If not, do your best to calculate the amount of water used by your household and come up with an estimate based on the capacity of your filter.
  • Can my faucet water filter remove limescale? For the most part, faucet water filters do not remove limescale. They aren’t capable of removing magnesium or calcium from the water, so keep this in mind.

Final Thoughts

The great thing about the faucet water filters today is they do a great job, and they do remove a wide range of contaminants from the water supply. Some filters are designed with better technology, and some can remove a wide range of contaminants, including 70 different possible pollutants.

When choosing a new filter, find one that is capable of filtering known contaminants in your own water supply. So test your water before purchasing your filter to determine which option is best suited for your home and family.
