The main criteria for choosing water filters

The main criteria for choosing water filters

Number of cleaning steps

The simplest filters have a single-stage cleaning system. They designed to deal with a certain type of pollution – mechanical, chemical, designed to remove iron, chlorine and other substances. Such a filter is selected depending on what initial condition is tap water;

Filters having two or more cleaning steps are much more functional and much better fulfill their responsibilities functions. As a rule, the first cleaning step is to remove mechanical impurities, subsequent purify water from chemical substances, iron and even bacteria. The disadvantage of such a system is whimsical maintenance and the presence of many components, each of which requires attention;

Module cartridge resource

Any filter element has its own resource and needs regular maintenance. Cleaning or replacing the filter carried out at intervals from once every 2-3 months to a time in year. Neglecting manufacturer’s recommendations regarding service regulations may result in reduced operational device characteristics and breakdown

Features of choosing a filter for water for washing

choosing a water filter for washing

Fine-cleaning complexes for installation in water system, allow you to solve many different tasks:

  1. Coarse water purification from impurities and large particles;

  2. Salt removal, ionization and sorption purification;

  3. Iron removal and softening;

  4. Mineral enrichment and conditioning of water;

Before choosing such a device, you should carefully analysis of water supplied to the main line for availability diverse pollution. Depending on the results appropriate filter systems are selected for neutralization of a source.

An important design element is the osmosis filter, which passes purified water, as a result of which the resulting liquid becomes almost a complete analogue of distilled water.

Preference should be given to filters equipped ion exchange resin inserts. Their task is to soften water and substitution of magnesium and calcium ions for sodium and potassium ions.

In order for the water pressure to be sufficient for daily operation, it is necessary to give preference to systems, filtering in which it is carried out under pressure from 2 to 3 bar. Of this quite enough for high-quality water purification without prejudice to pressure water.

Features of the choice of flow filter

Flow filter – a great mobile option that you can to take with you on a trip, business trip or to the country.

Preference should be given to collapsible models with interchangeable filters.

  1. The pressure force in this situation plays a secondary role: for such operating conditions are quite enough models whose performance will be at a level from 0.3 to 0.6 liters per minute.

  2. Functional features of the filter are selected based on water quality and the presence of certain impurities in it, as well as chlorine, iron, phosphates.

Features of choosing a jug filter

The universal volume of the filter jug ​​is 1-1.5 liters;

  1. Cartridges used in everyday life should do well deironize water, as well as clean it from chlorine and various impurities;
