Filters for water under the sink - which is better?

No one will argue that the water supplied from the central water supply to our apartments is far from ideal and contains manyimpurities. Having tested a lot of water purification systems, most consumers tend to install flow-type filtration devices. In this article we will look at the water filters for washing - which is better to set for household use, you can determine after reading the information provided.

The main varieties of

filters All the advantages of water filters for washing under water can only be assessed in comparison with other water treatment systems. The modern market offers us the following varieties of water treatment equipment:

1. Jug filters are the most affordable and primitive variety of purification systems for preparing water for its further use. The main purpose of this kind of device is to remove excess chlorine, unpleasant odors, mechanical impurities and its partial softening from the liquid. Jug filters have compact enough sizes that provides their mobility and convenience in operation.

Important! All jug water treatment systems need a frequent replacement of the filter element, since it is represented by cartridges with very little resources and are usually capable of cleaning up to 300 liters of water.

1. Filter nozzles are water treatment systems that are installed directly on a water tap. The main disadvantage of such equipment is a relatively small amount of purified water.

Important! When using a packed filter, you will need an additional storage tank for storing purified water.

1. Filter under the sink - filter systems that are installed near the crane and attached to it using a flexible hose. The resource of this filtration system is designed for 1000-2000 liters and is represented by an effective filtration material. Most often, activated carbon and polypropylene fiber are used as filter elements in such devices.

Important! Depending on the model you have chosen, the filter for cleaning water under the sink can have from 3 to 8 degrees of water treatment. The most effective are reverse osmosis systems that can remove about 99% of the contaminants contained in tap water.

Design features of the

sink filters The filter for cleaning water under the sink consists of a casing that is represented by several nozzles for the installation of replaceable flasks or cartridges. All these elements of the construction contain different filtering substances. Thanks to the design features of the device, water passes through each of the cartridges, which specializes in cleaning water from a certain type of contamination.



Important! The main advantage of flow filters is the ability of the user to independently combine a set of water purification cartridges and flasks. Selecting filtering substances depending on what kind of water enters your apartment.

Filter cartridges

The modern market offers consumers the following varieties of water purification cartridges:

• Ultrafiltration module is a device that provides mechanical cleaning of liquid. This filter element is represented by non-woven polypropylene, which has a small pore size. Such a device is designed to purify water from such mechanical impurities as rust particles, sand, clay and other types of debris from water intake sources.
• Coal filter is a specially designed cartridge that is filled with activated carbon. It is this substance that is famous for its unique sorption properties that will help to rid the water of chemical-type pollution. Since the carbon filter absorbs harmful components, it should be changed from time to time.

Important! If you do not replace the charcoal filter in time, instead of cleaning the water, you risk getting its pollution when passing through a filter that is saturated with harmful compounds.

• Ion exchange type cartridges. Such purification systems are based on the principle of chemical metabolism between water and a special resin. Thus, excess heavy metals, magnesium and calcium can be removed from the liquid.
• Deironing cartridges are special devices that complete the water treatment system in case of need to remove water from surplus iron. Such a chemical composition is observed mainly in water extracted from artesian wells.
• Module for processing with ultraviolet light. Such purification systems are equipped with a built-in UV lamp, which due to radiation is able to render harmless most of the chemical compounds, viruses and microbes contained in the water.

• The reverse osmosis filter is a water treatment system that has very small pore diameters through which only the smallest trace elements can penetrate. A cleaning membrane of the cartridge made of semipermeable polypropylene is produced and installed in a folded form. With the full use of reverse osmosis systems, water purification from 99% of impurities is provided.
• Structurizers are a system with bioceramic filler, which helps to restore the structure of water molecules. A similar effect can be achieved in case of freezing and consumption of melt water. This is due to the fact that scientists have learned that the benefit or harm of water depends not only on its purity, but also on the integrity of the molecular structure.

Installation of the

flow-through water purification system The installation of a water filter under the sink is simple enough and does not require special skills. That is why with the solution of this problem the owner of the water treatment system is able to manage independently, thereby saving money on the services of specialists.

Important! Each flow filter is provided with detailed instructions on how to install it, which greatly simplifies the installation procedure. The installation scheme of such equipment is almost the same and does not depend on the model or the number of filter flasks.

This procedure consists of the following steps:

1. Select the installation location.
2. Assembling the frame elements.
3. Installation of a separate tap for purified water.
4. Mounting the storage tank and its connection to the drain.
5. Start the filter for its further operation.

Basic selection criteria for

Most people have a logical question - how to choose a water filter for washing? For the organization of a qualitative and efficient water treatment system, pay attention to the following system characteristics:

• The filter dimensions should allow not only to install it under the sink, but also to make it convenient to maintain it.
• The head to which the filtration system is designed must fully comply with the actual or, at a minimum, not have a lower value. Otherwise, you will have to install a water pump in the system in order to increase the pressure in the pipeline.
• All elements of the water treatment system must be strong enough and reliable. Often made of plastic water purification flasks do not withstand water pressure and give a crack, which inevitably leads to the need to replace them. Therefore, experts recommend to give preference to models with filters made of stainless steel or glass-filled plastic.
• It is also very important that all materials used in the manufacture of the filter and water-contacting elements of the structure are environmentally safe.

Important! If the plastic parts have an unpleasant smell, then it is worthwhile to prick up and give preference to the product from another manufacturer.

Asking which water filters are best for washing, special attention should be given to their cost, namely, to estimate the following price characteristics of the model of water treatment equipment:

• initial cost of the device;
• price of consumables and frequency of their replacement;
• prime cost of obtaining 1 liter of purified water.

Rating of water filters for a sink

The most popular water treatment systems in the current market are water filters for washing the following trade marks:

• Aquaphor.
• Atoll.
• Barrier.
• Geyser.

Experienced users recommend choosing models of filter equipment with a first bulb made of transparent material. In this case, you can clearly assess the suitability of the filters and the need to replace them.

Important! Estimating the cost of a particular model filters for water under the sink, consider the cost of installation works. So, the company "Aquaphor" offers to carry out the initial installation absolutely free of charge, but the filters "Atoll" are installed by the masters for a fee.

In this article, we also told you about the advantages of cleaning water filters under the sink and the features of choosing such equipment. Sincerely we hope that the information given by us will help you to provide your house with clean and useful water.
