Under-sink water filters

An under-sink filter is installed under the kitchen counter and connected to the water pipes. A tap for clean water is the only part of the filtration system on display. Most often, this is a multi-stage filter with several cartridges performing different functions.

An under-sink drinking water filter is the best solution for a family. It is more productive than a filter jug, allowing for purification of high water volumes for preparing home-cooked meals and drinks.

How to choose a proper under-counter filter?

The choice depends on the purpose of water treatment and the quality of municipal water. There is a number of problems and solutions. If you doubt the quality of your tap water, you can take the sample to the lab for testing and see what exactly is wrong.

Types of under-counter filters

Reverse osmosis systems

Reverse osmosis (RO) is the most advanced water treatment technology. With an RO filter, you get fresh drinking water any time you need. Also, forget about plastic waste: no more disposable bottles decomposing for hundreds of years.

The main component of an RO filtration system is a special membrane. It removes hardness salts, and the water becomes perfectly soft. Protection against scale saves you the trouble of constantly repairing household appliances.

Any reverse osmosis filter has a mineralization unit for the balanced water composition.

Reverse osmosis systems of new generation

The AQUAPHOR RO series presents the advanced models based on the reverse osmosis technology. They take up twice less space under the sink than the classic systems thanks to a compact built-in storage tank. Also, less water goes wastefully into the drain.

Under-sink flow-through filters

In adsorption filters, the “main character” is coconut shell activated carbon in the form of carbon block. It adsorbs harmful impurities like chlorine and its compounds, phenols, trace pharmaceuticals, etc.

Under-sink filters with hollow fiber (HF)

Some filters contain HF membrane. It provides reliable protection against bacteria without the use of any chemical additives. The filtered unboiled water is absolutely safe for drinking and preparing baby food.

What comes in a set?

An undersink filter with a separate faucet for clean water is a comfortable solution. No need to think about buying anything extra since most models are already “all in one”.

A standard set of suitable replacement cartridges is always included when you buy a filter. Replacing the cartridges will not be a problem, because the design of most AQUAPHOR filters allows you to easily remove and attach the cartridges without any special tools.

Different cartridges have different service life, so it is important to follow the manual: on average, pre-filtration cartridges are changed every 6 months, membrane cartridges last 1-1.5 years, and carbon block units — around 1 year.

So, besides a filter, you get cartridges, a faucet for clean water and all the spare parts needed for the system installation: clamps, tubes, plugs, etc.

Buying an under-counter filter

AQUAPHOR filters are manufactured only with high quality materials, while their price remains affordable. Buying a filter for an apartment or a whole house means investing in your future. Water filtration system is necessary for any person in the modern world to maintain the quality of life so that clean, fresh water is always available.
