Filter for tap water - how to choose the best option

Water supply

As you know, in most localities of our country, water quality raises big questions, and if water supply organizations cope normally with the issue of eliminating bacteria and disease-causing organisms, the work on improving the properties of water and its purification is practically not carried out. That is why it is recommended to install water filters for water purification in every home, and we will consider them in our article.

Types of cleaning

Water main filters for plumbing in the apartment are called so because they need to be installed directly on the plumbing, i.e. highway. They differ both in design features and in the range of functions performed. The following types of cleaning can be distinguished:

Mechanical	This option involves the removal from the fluid of all mechanical impurities: particles of rust, clay, lime scale, etc. Most of the options perform this function, as it is a fundamental factor in water purification.
Chemical	As you know, tap water is treated with chlorine to kill pathogens. In addition, the composition may contain other metals and trace elements that adversely affect human health, which is why there are filters to solve this problem.
Biological	If the water intake is carried out from a well or a well, then there is a chance that bacteria and microorganisms that cause various diseases can enter the water. That is why such communications require nodes designed to destroy all unwanted germs.
Water softening	A large amount of dissolved salts causes increased water hardness, which causes lime deposits in the pipelines, and water is not well suited for food use. Special devices can soften water

Tip! It is better to acquire universal systems capable of dealing with several types of pollution at once, this will ensure the best cleaning quality.

The tap water softener filter is filled with a partially soluble reagent that can be added as it dissolves.

Types of construction

Consider the most popular and popular options, it should be immediately noted that this is not a complete list, it will take more than one review to list all possible types. (See also the article Filter for a mixer: features.)

Coarse nodes

This option is quite common due to the following factors:

The price of the product is very affordable..
The design is a brass or bronze case, in which, under a slope or at a right angle, there is a special grid capable of holding mechanical impurities.
The system can be cleaned by flushing the mesh cartridge., which is quite easily removed.

The coarse filter is simple and reliable.

Fine cleaning devices

This option is more productive than the first and has the following advantages:

Most often it is a flask in which a special replaceable cartridge is inserted., which is easily replaced with your own hands.
The type of filter unit used depends on your water.. Cartridges can be filament, corrugated, made of foamed or woven polypropylene, etc.
By appointment, such options are divided into devices for hot and cold water supply.. The first option can be distinguished by a transparent flask, while in the second it is usually made of heat-resistant opaque plastic or stainless steel.

Note! It is possible to put filters for hot water on a cold main, while doing the opposite is strictly prohibited.

This is what the considered option looks like in the system.

Another option for fine cleaning is a wash filter, which has a special mesh segment, which, unlike the models we have reviewed, can self-clean without disassembling the product. There are modifications on the market with both automatic and manual flushing; And how to make cleaning, the instruction will prompt.

Wash filters are very convenient to use.

Reverse Osmosis Devices

This option is a large design with the following nodes:

The main working unit is a special membrane capable of removing both mechanical, and biological and chemical impurities from water., this is both a plus and a minus.
To saturate the water with all necessary microelements, a mineralization unit must be present in the system..
For the design to work efficiently, the pressure in the water supply system must be at least 3 atmospheres., otherwise, the fluid will not be forced through the membrane.
The main disadvantage of such options is the high price., that is why they are not as widespread as others.

Reverse Osmosis - High Efficiency System

Softeners

There are two main options: inexpensive ones with filling with polyphosphate crystals and more expensive regenerative blocks.

The first are simple - the case is filled with crystals that need to be changed every 3-4 months. Such water can not be used for food purposes.

The second option is a filter column with a backwash compartment and a tank for the regeneration solution (usually common salt). Systems work very efficiently, but the main problem is the rather high cost.

There are other options that are used in different conditions, some of the designs are equipped with separate cranes, others join existing communications. (See also the article How to clean the pipes: features.)
