What does an under sink water filter do?

As the name suggests, an under sink water filter is a device which is installed under a kitchen sink, and connected to the cold pipeline in order to filter the water running through its own dedicated faucet, or through the main tap.

The idea is to have access to purified water for drinking, cooking, preparing beverages, washing fresh produce, and other needs right out of the tap. At the same time, it saves money for having to invest in a whole house water filter.

The under sink water filter is an on-demand filtering system, which means you won’t waste any water. It will also save you money and help the environment by eliminating the need to buy bottled water for your drinking needs.

It is important to note, that an under sink water filter will help purify the water from the specific faucet, and not in your entire home.

There are different types of under sink filters, so it is essential to understand the different features you should look for to make an informed choice when buying the one for your needs.

The features to look for when buying an under sink water filter

Although the purpose of all under sink filters is the same, they differ by type, size, filtering method, and other features.

Here are the main characteristics to keep in mind when choosing the best under sink filter.

The water pressure

This feature is very important because nobody likes to have to wait for ages for a glass of water to be filled up. You should opt for a filtering system which can provide you with a good flow of water. This is especially important if you already have a low-pressure flow in your home.

Of course, you shouldn’t compromise with the filtering capabilities of the filter in order to ensure you have a good strong flow of water. Try to find an under sink water filter which combines efficient purification with satisfactory water pressure.

Also, check which types of contaminants present in your water, and buy a filter according to the quality of your water.

The filtering capability

Since the main goal of every water filter is to remove the contaminants from the water, you should choose an under sink water filter which is capable of removing the pollutants from the water, which you are worried about. The quality of the water differs from one area to another. There is also a difference between getting water from a municipal source and a private well.

So, it is a good idea to run a test to find out the content of your water. You can do so by using a home test kit or have your water tested by a professional. You can also ask your city to provide you with the characteristics of your water, but then again, it may be contaminated with pollutants on its way from the treatment plant to your kitchen sink.

The manufacturers of the water filters offer specifications regarding their filters. Some are simpler, while others have multi-stage filtering and are capable of removing more contaminants.

Remember that while a water filter may work perfectly for one household, it may not be suitable for yours. So buy a filter according to your specific needs and your water quality.

Also, for peace of mind, you should check the filtering systems for NSF, ANSI, and WQA certification and testing for their efficiency of filtering harmful contaminants.

The ease of installation and maintenance

While many of the under sink water filters are designed to be suitable for DIY installation, you may want to check out how simple or complicated the installation process is before buying a water filter.

Thankfully, most of the under sink water filters on our list come with detailed instructions, and many online videos on YouTube show the installation process, which can be especially useful.

It makes sense to take the time to watch an installation video before proceeding to buy a certain under sink water filter.

This can save you a lot of hassle as well as money for having to hire a professional plumber.

As for the maintenance, this is another feature that you should pay close attention to. You wouldn’t want to struggle with the filter cartridge replacement every time, right?

Many of the good quality under sink water filters offer very easy filter replacement, and this is something worthwhile considering, given the fact that you will be doing this on a regular basis for a long time.

The capacity and longevity of the filter cartridge

The different cartridges used for purifying the water have a different capacity and need to be replaced after a certain amount of water has been filtered, or after a specific time period.

The higher the quality of the cartridge, the longer it will likely last.

But keep in mind that how often you will need to replace the filter cartridge depends on your water use, as well as the quality of the water. The recommendations given by the manufacturers are usually based on average consumption and average water quality.

It is a good idea to check how much the replacement cartridges cost as well, in order to calculate what your ongoing costs for the maintenance of your under-sink water filter will be.

Is an under sink water filter better than a countertop one?

You may be deliberating about whether it is a better idea to invest in an under-sink water filter, or opt for a countertop filter instead.

Here are the pros and cons of both.

Under sink water filter


  • It doesn’t take up valuable countertop space
  • It is hidden out of sight underneath the sink, so your kitchen design won’t suffer
  • This type of filter has a good filtration rate


  • The under-sink systems are usually bulkier than the countertop ones
  • It can be harder to install, as some countertop filters require little or no installation at all
  • Reaching underneath the sink to replace the cartridges can be a hassle if you have a bad back or other problems squatting or bending down

Countertop water filter


  • These are usually smaller in size than the under sink ones
  • They are generally easier to install than the under sink filtering system


  • They are usually slower when it comes to filtering than the under sink units
  • They will take up countertop space, and may interfere with your kitchen design

Do you need an under sink water filter?

Having easy access to filtered water is definitely a good thing for just about anyone, but an under sink water filter may be a suitable choice for some, and not quite so suitable for others.

You may benefit from an under sink water filter if:

  • You don’t have a whole house water filter
  • You have limited space and cannot install a larger filtering system
  • You have a limited budget and do not want to pay for a whole house filtering system
  • You want a filtering system which you can install and maintain by yourself, rather than hiring professional plumbers
  • You want to save money and help the environment by limiting the bottled water you are purchasing
  • You want better-tasting tap water
  • You want to make sure you wash your vegetables, fruits, meat, and other products with purified water
  • You want the water you use for making lemonade, coffee, and other beverages to be clean
  • You want to ensure that your pets drink purified water too

The pros and cons of using an under sink water filter

Here are the advantages of having and using an under sink water filter:

  • Your water will taste better, and there will be no nasty odors and tastes, which will prompt you to drink more water and stay hydrated
  • The water you will use for cooking, prepping food and beverages will be clean and safe from harmful pollutants
  • You can limit the money you spend on bottled water and help the environment as well as your budget
  • You can pour purified water from your tap into a glass bottle and take it with you instead of buying bottled water
  • It saves space, as the unit is hidden under the sink in the cabinet
  • The installation of most under sink filters require minimal DIY capabilities and efforts
  • Under sink water filters are affordable, and their cartridges are affordable as well – so it is definitely less expensive than buying a larger filtering system for your home
  • The maintenance of the under sink water filter is pretty simple


  • The under sink water filter will ensure that you have access to clean drinking water from one faucet only, unlike a whole house filter which ensures that clean water runs from every tap in the home
  • Conventional under sink filters require the installation or use of a separate faucet
  • If you choose to connect your filter to your main faucet, you will be using purified water for all your kitchen needs, including washing dishes and others, which will waste the clean water

Simple vs. conventional under sink filters

There are two main types of under sink filters for water – simple and conventional. The simple ones are referred to as such because they are simpler to install, and not because of their filtering qualities. Conventional types require a separate faucet and are more challenging to install.

Here are the pros and cons of each type.

The simple under sink water filter pros and cons

Simple under sink filters connect to the cold water line, and all of the water passing through the cold water faucet will be filtered. These filtering systems do not require drilling holes in the sink for additional faucets.


  • They are the less expensive type
  • They provide a good water flow
  • They do not require the purchase and installation of additional faucets
  • You won’t have to drill holes or make modifications to your sink and countertop


  • Since all of the water passing through the cold water faucet will be filtered, you will need to change the cartridges more often and will be using purified water for every other task in the kitchen
  • Since they provide a higher flow, in some cases, some contaminants can find their way through the filter

The conventional under sink water filter pros and cons

The conventional under sink filters are the older type of the two. They require that the water running through the main cold water line is diverted to the filter via a hose or tube. After that, the filtered water is sent to a separate faucet that needs to be mounted on the sink or countertop. Only the water passing through the added faucet will be filtered, while the regular taps will provide you with unfiltered water.


  • You can use filtered water only when you need to, so you will not waste it and won’t have to replace the filter cartridges as often
  • The reduced flow rate in these filters allow for longer contact of the water with the filter medium, which means that your water will be properly filtered at all times
  • These filters can be installed on any kind of plumbing


  • You will need an additional faucet, or a three faucet system
  • You will need to drill holes in your sink or countertop to add the faucet
  • The flow rate from the added faucet is slower

What kinds of contaminants can an under sink water filter remove?

The different under sink filters have different capabilities for purifying the water from contaminants. You should test your water quality and content prior to buying a filter, in order to ensure that it will be efficient in removing the pollutants you are specifically worried about.

In general, you can expect that a good quality under sink water filter can remove:

Bad taste and odors

Since most of these filters use activated carbon for filtering, any bad tastes and odors from chlorine, sulfur, rust, and other chemicals and pollutants will be absorbed by the filter. This will make your water taste, smell, and look better.


Most filters will efficiently remove sediments like dirt, sand, dust, scale particles, and others from the water running in your kitchen sink. This is achieved via carbon filters and spun or pleated polypropylene (PP).


While chlorine is essential for disinfecting and keeping the water safe, excess chlorine can be harmful to people with sensitivities, and can also affect the taste, smell, and the feel of the water. Most under-sink water filters can successfully trap the excess chlorine and its smell and taste thanks to the activated carbon pre-filters and the main carbon filters used.

Heavy metals

Under sink water filters with KDF and activated carbon filters can successfully remove the harmful heavy metals. KDF filters use an oxidation-reduction process to remove chlorine, mercury, lead, hydrogen sulfide, iron, and other heavy metals, which could be contaminating your water.


Some under sink filters have an Activated alumina filter, which is capable of removing most of the fluoride contaminating the water. These porous filters can also absorb most of the arsenic, selenium, and other harmful chemical pollutants from the water.


As mentioned above, the under sink filters that have an activated alumina filter can successfully trap a large percentage of the arsenic, selenium, and fluoride present in your water.


Under sink water filters, which use an anion resin medium, are capable of removing the nitrates from the water. Nitrates are harmful to everyone but are especially dangerous for young children, older people, and those with underlying health problems.


Filters that include action resin in their cartridges are capable of removing the excess magnesium and calcium from the water and thus help prevent limescale buildup on your faucet, in the sink, and spots on your glasses and utensils.

Bacteria, viruses, and microorganisms

Most good quality under sink water filters are capable of removing the harmful microorganisms from the water, including the cysts of parasites, viruses, bacteria, fungi, and others.

Final words

As you can see, an under sink water filter could be an excellent alternative to a small-capacity water filter pitcher or an expensive whole house water filter system.

Under-sink filters will ensure that you have access to clean, safe, and tasty drinking water whenever you need it – right from the tap.

They are easy to install, easy to maintain, and are reasonably priced.

With an under sink water filter, you will help the environment and save money for having to buy bottled water.

You will also be able to wash your vegetables, fruits, and other products with safe water and use it for food prep, cooking, and making beverages.

Your whole family, pets, and your house plants will healthier and adequately hydrate with a system like this.

Hopefully, this detailed guide has helped you find the most suitable under sink water filter for your needs, and pretty soon you will be enjoying the numerous benefits of having access to clean drinking water straight out of the tap.
