Why choose a filter under sink?

When you cannot or do not want to install a filtration system on the entire distribution of your home, which is particularly the case in rental, filtration on a single draw point (sink, shower, sink …) is an easily adaptable solution almost everywhere. However, the filter on tap has the disadvantage of being often unattractive, even bulky for certain models.

Types of under-sink filtration

There are two main categories of filters under the sink (or under the sink): the direct distribution filter and the remote distribution filter.

Direct distribution

The filter under sink with direct distribution is inserted between the cold water inlet (wall) and the cold water inlet of the tap, the mixer or the mixer . Placed in the cabinet under sink or under sink, the filter is invisible . It requires no electrical energy and works as soon as cold water filter is drawn from the tap.

On the work surface or the basin, there appears to be no change since the water is always drawn in the same way: by opening the cold water filter flow from the original tap.

Remote distribution

The under sink filter with remote distribution is similar to the previous one in its part hidden under the sink or in the cabinet, but its filtered water draw point is independent of the tap. If the connection to the water filter supply is as simple (just a T-connector or a self-drilling tap), the distribution of filtered water requires the installation of a separate tap for filtered water which requires a little space on the basin , in order to place the additional tap which requires the drilling of the sink, basin or sink.

The separate tap for filtered water reduces the consumption of spare cartridges and filters by filtering only the required amount of water.

The filter under sink (or under cabinet in a bathroom) can be easily installed, and remains discreet while ensuring quality filtration to obtain clear and purified drinking water on the sink or sink. taste or smell.

Advantages and disadvantages of filtration under sink

If in practice these two types of filtration under sink are relatively similar, it is the aesthetics and the use that you make of them that will determine your choice.

Direct filter

The installation of the direct filter is very simple and its size is reduced . Its draw point is directly integrated into the tap in place and is completely invisible . In addition, it is easily movable. It offers a high flow rate (± 100 liters / h).

However, this system is only compatible with cold water distribution .

Dedicated tap filter

The dedicated faucet filter offers an additional draw point reserved for filtered water. It allows you to choose, depending on your use, between filtered or unfiltered water.

However, this solution is less aesthetic, since it requires the installation of an additional tap. Also, note that the draw point is offset from the mixer. This system induces a hole in the sink or the vanity unit. Finally, the dedicated tap filter offers only a contained flow rate  : 60 liters / h maximum.

Choose a filtration under sink

The filtration level of one or the other solution being almost the same, it is the choice of the type of installation which must prevail during the purchase. While a direct filter on an existing tap allows a higher flow rate, it is above all its very simple mounting (without hole to be drilled or additional tap to be fixed), as well as its total discretion which can decide its choice. But in return, we will no longer have the option of choosing at the draw point if we want filtered water or not.

Tips for installing a filtration under sink

For installation (but it must be ensured before purchase), the connections acceptable by the type of filtration system are common flexible connections . Before buying a filter under a sink with a separate tap, it is necessary to make sure that the unit, sink or sink can receive the dedicated faucet (space on and under the sink, diameter of the drilling hole) . Similarly, if you have to pierce the basin, the sink or the worktop, you must check that the material allows the drilling and that you have the drill bit of the appropriate diameter, unless you have to acquire this extra bit.

Regarding maintenance, it is relatively simple since it consists in changing the filter cartridge according to the manufacturer’s recommendations.

Price of filtration under sink

Obviously, a filter under sink with its flexible connections necessary for connection seems less expensive than a filter under sink delivered with its dedicated tap. But there are so many low-end equipment that sometimes the prices are between one and the other system. It is therefore essential to ensure, in the case of a filter under sink with its tap, that the latter is of good quality (seat, seal, etc.) and benefits from the longest warranty possible . As this is the only truly mechanical part, it is this part which is subject to wear, breakage and a leak.

It is important to check that the tap, if supplied, with a filtration kit under the sink is fitted with standard wearing parts allowing easy replacement.

  • A filter under sink which is installed before the existing tap can be bought at just under  $ 100 .
  • It takes about 300  $ for the same type of filtration under sink but delivered with its separate tap.
  • On average, a filter cartridge for this type of filter sells between 10 and 30  $ depending on the brand, and many filters under sink have a cartridge replacement indicator.

InexpensiveWhen shopping for an under-sink water filter, you can find models you install yourself which last up to 6 months for $40 or $50. As you move into the $60 to $100 range, you can find higher capacity models, which may last as long as three years.

Mid-rangeOnce you move to the $100 to $150 range, you find premium quality multi-stage under-sink water filters that remove a wider variety and greater percentage of contaminants.

Expensive: In the $150 to $250 price range, you find reverse osmosis filters that remove all harmful minerals from your drinking water accompanied by a multi-stage process that infuses your water with healthy minerals.

What contaminates water to require a under sink water filter?

Quality water filter can be contaminated by various contaminants, which are generally impurities or pollutants . Sometimes filtering is necessary to purify the water of bad tastes and odors that are not actually harmful, but can be unpleasant.

Rust and other sediment can settle in household drinking water, clog a kitchen sink pipe, and affect household appliances such as the ice maker and washing machine.

Bacteria and parasites can cause health problems , especially for young people, the elderly and anyone with a weakened immune system. If well water is more likely to be contaminated with bacteria and parasites, the water treated and purified by the municipality may be contaminated with pathogenic elements such as cryptosporidium cysts and giardia which can cause protozoal infections.

Lead can also be present in water, although the use of this metal in pipes has been prohibited since 1995. Houses built in the 1980s may still have pipes connected with lead solder. Some municipal water systems may be composed of elements containing lead. Lead in water is tasteless and odorless, but should be avoided as much as possible. You can find filters that reduce it, but if you are concerned about the risk of lead in your domestic water, have it tested by a professional.

Other potential contaminants, including pharmaceuticals, heavy metals and viruses, may be present. Before choosing your drinking under-sink water filter, find out the content of your water and determine what you want to filter and dispose of . Most city water suppliers, whether it is the municipality or a private company, must publish an annual water quality report. If you would like details on the tap water you use, make sure to refer to the health monitoring results for drinking water quality in your area.

What are the water filtration methods?


  • The cartridge under-sink water filter

Cartridge water filters under sink are multi-stage filtration systems , under the sink, which treat the water by passing it through each filter cartridge, each containing a water purifier, a water softener and nanofiltration elements. Thus, rust particles, dirt and sand are completely filtered.

  • The activated carbon filter

The carbon filter reduces certain contaminants by chemically binding to the activated carbon. This type of filter is quite common for the treatment of water with strong tastes and bad odors caused by chlorine. Some activated carbon filters also filter out other corrosive contaminants such as lead and mercury.

  • The reverse osmosis filter

Osmosis units operate by reverse osmosis. Pressurized water passes through a reverse osmosis membrane, which collects contaminants larger than water molecules . Although an osmosis membrane filter does not remove chlorine, it does reduce other contaminants that the activated carbon filter cannot filter.

Reverse osmosis systems generate several liters of wastewater for each cubic meter of filtered water. They can also remove unwanted mineral salts in addition to contaminants. Some systems are therefore designed to restore these minerals in water. Reverse osmosis can also filter out contaminants such as lead, bacteria, parasites and viruses.

  • Water filtration by ion exchange

The ion exchange water filtration system replaces contaminating ions with more tolerable additives . Water softeners use this filtration process to treat hard water by exchanging magnesium and calcium for sodium. Ion exchange also filters cadmium, copper and zinc.

  • Oxidation-reduction filtration

This household best under sink water filter converts contaminating molecules such as chlorine, into different molecules without negative effects. This filtration method eliminates certain things such as chlorine, lead and bacteria.

  • The ultraviolet filter

UV filtration uses ultraviolet light to kill certain bacteria, viruses and cysts . However, this technique does not remove chemicals.

How to choose a under-sink water filter?

The filtration methods listed above can be used in different formats and combinations. So choosing between a multi-stage cartridge filter or a reverse osmosis filter is not always a question of filtration level . Although ROs often offer the best filter water, there is a filtration system for your situation that may not work for other users. So the best thing to do before choosing one is to have your water tested for contaminants.

What is the use of an under sink filter?

Triple filtration under sink

This  under-sink filter  uses triple filtration technology. This system is used to retain materials and particles that may be suspended in your water. Its role is therefore to remove impurities from the water such as:

  • Chlorine
  • The lead
  • Zinc
  • Pesticides
  • Mercury

A  filtration sink  also helps eliminate bad water taste and odors.

The advantages of an  under sink filter  :

  • The water for drinking and cooking is purer
  • Coffee, tea and your food taste better
  • Your ice cubes are formed from quality water

In order to combine efficiency and aesthetics, the filter fits under the sink discreetly. The  filtration sink  therefore requires no plumbing and provides water pure directly from the tap.

Filter under sink with activated carbon

A  filter under sink  with activated carbon is above all an anti-chlorine solution. Its function is to eliminate bad taste. The water recovered after  filtration under the sink  therefore has a natural taste and is rid of its bad odors.

The advantages of  filtration under  activated carbon sink :

  • The filter reduces bacterial growth thanks to its antibacterial coating
  • Water gets rid of chlorine, its bad odors and its bad taste
  • Cartridge installs easily under the sink

By the way, it is necessary to remember that drinking good quality water improves hydration level, mental clarity and energy performance. Purified water reduces acidity, inflammation and prevents disease, all for a better immune system.

A under-sink water filter also has a practical aim: the reduction of limescale. Removing limescale is generally the most tiring fight to fight when cleaning your sink and the same is true in the water we drink or use to wash! “Hard” water (= rich in lime) can cause a lot of annoyances that should not be overlooked on a daily basis: tight skin, itching, etc. So imagine the consequences of drinking it? To remedy the problem, a water filtration system is the best solution. Furthermore, if you consider that your tap water is less tasty than bottled water, perhaps it is because the latter is too chlorinated? In fact, chlorine is very often responsible for water with an unpleasant aftertaste. If you like to consume tea and coffee without moderation, so it is better to filter your water, because in large doses, lime and chlorine do not mix well in the body and can have very significant negative consequences on our state of health. A good filtration of water allows, in summary, to reduce the quantity of products and harmful elements and to give it a better taste, for your greatest pleasure.

How to choose a under-sink water filters?

A filtration device has many advantages, but with all the models on the market and manufacturers who redouble their inventiveness to seduce you, it may seem difficult to know which one is right for you. So how do you choose it? We help you in your choice.

1. The filter carafe: the most widespread and practical solution

Before any purchase, be aware that the water filtered by the carafe must be consumed within 24 hours, just like when drinking bottled water. Indeed, the proliferation of bacteria should not be overlooked.

Thanks to an activated carbon filter and an ion exchange resin, the filter jugs remove lime, chlorine, nitrate and other pesticides possibly present in the water. It is obviously noted that the efficiency of filtration can vary depending on the jug, just like any product in the same range. Carafes are therefore very useful for people who do not appreciate the taste of tap water at home or for coffee and tea enthusiasts , because part of the lime is removed, the machines are therefore less clogged and therefore more durable over time. What more?

2. The filter on the tap: a process not to be overlooked

Based on the same principle as that of a filter carafe, the latter is to be installed directly at the outlet of the tap and seems, in fact, more effective than the latter in removing nitrates, with a rate of 99% for the most filters distributed in shops or supermarkets.

3. The osmosis filter: a complex but formidable system

This system is undoubtedly the most complex and the most difficult to install, because it requires a whole apparatus under the sink. Its membrane pierced with such fine holes allows only water and no other residue to pass through. You can consume water without bacteria or pesticides or the majority of problematic minerals (lead nitrates, potassium, etc.). Be careful however, because in its filtering, the osmosis filter removes precious minerals from our body, these same minerals present in mineral water bottles.

4. The ceramic filter: rather to use for your pool 

Like the osmosis filter, the ceramic filter also has very fine holes. Even if this takes up less space than the previous one, it is used above all to make rainwater drinkable, knowing that it will already have been filtered.

Precautions for use 

First of all, note that if you do not consume water for a certain period of time (trips, vacations), it is better to throw away your filter and replace it directly, since it will be the preferred nest of bacteria. In addition, as a under-sink water filters eliminates pesticides, pollutants and other undesirable, the maintenance of the latter should never be neglected. Indeed, these multiple systems require rigorous maintenance, because in the long run, if you neglect them, the filters will lose their primary usefulness of filtration and risk all the more polluting the water that you consume.

An activated carbon filter, for example, will stop working and will no longer filter, it would be a shame to get to this point. You should therefore take care of it mainly for reasons of hygiene and health, but also for financial reasons. If you maintain it properly, a under sink water filters, whatever its use, can really last over time and will save you a lot of money!


How a under sink water filter works

Although tap water is qualified as potable, it can contain traces of antibiotics and other foods that can impact our body in the long term. It is therefore not completely pure per se. In order to get rid of these water pollutants , installing a under-sink water filters is an effective solution without risk to health.

Unlike the water softener, the operation of the under sink water filters is simple, knowing above all that its main mission is to facilitate the purification of water for domestic or professional use.

Indeed, simply place the under-sink water filters on the tap or under the sink to prevent the infiltration of polluting elements. The water thus filtered will later assure you a pleasant taste while being digestible.

Good to know: fixing the under-sink water filters under the sink requires some DIY work. If in doubt, you can hire a plumber to install.

The different types of under sink water filter

Industrial under-sink water filters, domestic under sink water filters for under the sink, the water filtration systems available on the market come in several types depending on the needs of each. Today, we will focus on the most used and widespread models.

Filter cartridge filters

Generally recommended to reduce water turbidity (cloudy water), filter cartridges are capable of retaining particles in suspension. It is a purely mechanical filtering system which does not use any active ingredient.

Depending on the size of the pollutants to be captured, it is possible to adjust the filtration capacity by choosing the appropriate filtration diameter. This varies from 5 to 100 microns.

Thanks to their special characteristics, cartridge filters lend themselves to several uses, whether to filter the micro particles contained in tap water, or to capture sand that may be present in a rainwater collector.

Although these devices are often washable, it is recommended to regularly replace the cartridge filters by opting for wound filters, the most resistant.

Magnetic filters

Like polyphosphate filters, magnetic water filters best are designed to limit, even eliminate permanently limescale or tartar through magnetic waves.

Both discreet and compact, these models can be easily installed in the kitchen and have the main advantage of requiring no consumables. Permanent magnet models don’t even require energy to operate.

Polyphosphate filters

This type of water filtration system incorporates an active compound whose objective is to limit or even completely eradicate any presence of lime or scale.

Can be installed before the devices to be protected (at the arrival of a cumulus tank for example) or at the head of the network (after the meter), polyphosphates filters are essential to prevent scaling of sanitary facilities and pipes in their whole.

Depending on the capacity of the filter and the water consumption, the active compound must be recharged once or twice a year.

Sediment filters

Designed to protect the filters installed behind them or to stop large substances contained in the water, sediment filters or “pre-filters” have a filtration capacity up to 20 microns.

These devices are often installed at the head of the network (after the meter) in order to limit the clogging of activated carbon or cartridge filters, and thus extend their service life and optimize their maintenance.

Activated carbon filters

The use of activated carbon in the filtration of domestic water brings only benefits for the family. It removes and even reduces not only the presence of chemicals in the water, but also the turbidity of the water and the level of certain heavy metals.

For example, activated carbon filters are recommended to soothe the taste of chlorine in tap water and give it a neutral taste.

These devices can be installed at the head of the network to reduce carbon fouling, knowing that it must be replaced at least once a year.

How to choose a under sink water filter

Now that you know how a under sink water filter best works and what are the main models on the market, you still need to know the different criteria to take into account when choosing the best under sink water filter for your needs. Whether on the Internet or in a physical store, the following parameters should be checked:

The price

Like the purchase of any other household equipment, the choice of a under sink water filter depends above all on its price.

Before focusing on the first cheap under sink water filter that is offered to you, ask yourself the right questions: is the price reasonable in relation to the quality of the product?

If in doubt, do not hesitate to consult online comparisons to determine average prices.

The brand

The quality of a best water filter depends on the reputation of its manufacturer. A recognized brand guarantees the reliability and performance of the device.

The quality

Finding a quality under sink water filter is not always easy, especially when you’re new to water treatment. To recognize a high-end under sink water filter , simply refer to the name of the manufacturer, but you can always seek advice from a professional.

Your needs

The choice of a under sink water filter will also be based on your personal needs, knowing that each model is intended for a particular use.

If there are many of you at home, it would be better to opt for a under sink water filter model that can filter a good quantity of water permanently. Either way, the advice of an expert will always be welcome when choosing a under sink water filter.

Tip: combine a under sink water filter with a softener

Although the advantages of the under sink water filter are multiple, it is sometimes recommended to couple this water treatment system with another device: the water softener. This is explained by the fact that the under sink water filter does not succeed in permanently blocking the lime contained in tap water.

Also, let’s not forget that water with a high calcium content is likely to cause discomfort on the body such as drying of the hair and skin, hence the interest of installing a water softener.

This device makes it possible to eliminate lime and its harmful effects on the human body while fighting against unpleasant tastes and odors caused by certain materials contained in the treated water.

It is also recommended to prevent scaling of household appliances and plumbing while ensuring their optimal longevity.



Are under sink water filters worth it?

According to expert recommendations, “because easy to install undersink filters use water pressure, not gravity, to push water through the filter, their filters can be denser, so they can remove a greater range of potential contaminants.”

How long do under sink water filters last?

Filters used in commercial settings should be changed every 4 to 6 months. Filters in residential settings should be changed every 6 to 12 months. Reverse osmosis, membranes, and additional alkalisers only need to be changed ever 2 years or 4 years, respectively.

Time: In general, replace your filter every six months. This is for normal usage (although I never know what the definition of “normal” is!). Replace the filter more often if you drink a lot of water. Taste: if your water starts to taste or smell funny, it’s time to change the filter.

What kinds of contaminants can be in water?

You’re probably familiar with the possibility of having lead in your drinking water, and some people are likely worried about excess fluoride or bacteria and parasites, but that’s barely scratching the surface — a plethora of other contaminants can get into your drinking water. Chemicals and fertilizers used to spray crops, a multitude of minerals from natural deposits in the ground, and improperly disposed of pollutants can also wind up in our drinking water. Beyond that there are pharmaceuticals, personal care products, cleaning products, and even car emissions.

How do I know which contaminants are in my water?

Get it tested. It’s as simple as that. Don’t depend on your town’s tests. These take place before the water enters your home, and there are many opportunities for additional contamination before the water comes out your faucet. You can purchase a drinking water testing kit and do it yourself or you can hire a service. The choice is yours, but until you test your water, you won’t know what type of under-sink water filter you need to buy.

How do I know if the filter I am considering will work for my water?

The National Science Foundation (NSF) has a number of different standards regarding chlorine, hazardous contaminants, pesticides, pain medicine, plastics, detergents, and more. To be sure you are getting the best under-sink water filter for your needs, the water filter packaging needs to state that the filter meets the NSF certification for the particular substances you are concerned with.
