How to choose a main water filter

The modern pace of life dictates its rules, and technological development has shown the reverse side of the coin - pollution of the environment. In many buildings, water supply networks supply so low-quality water that the issue of its purification becomes more and more relevant. The methods of filtering and types of systems will be discussed in this article.

Types of the main filtration devices

filters can be made of metal, reinforced plasteak or stainless steel. The type of material depends on the temperature of the water to be cleaned. In this regard, experts divide the device into three types:

• main filter for hot water;
• main line filter for cold water;
• universal filter.

Selection of main filters according to the degree of purification

The main filters for water purification are cylindrical devices, inside of which are installed cartridge-replaceable parts, which actually perform the filtering function. Such devices are mounted directly into the water supply system, due to which they received their name. To perform fine cleaning, a backfill is applied, which has a filtering effect. The type of backfill used is determined by the nature of the contamination. For coarse - a grid of steel with small cells.

By the degree of cleaning, the main filters are divided into three categories.

1. Single-stage , which differ the least degree of purification. The cartridge in this type of filter must be replaced with a frequency of 1 time in six months. These devices are able to purify water from coarse particles and suspensions, such as sand, sediment and rust.
2. Two-stage , which have a higher water purification ability. The apparatus is equipped with a mechanical barrier and a carbon carbon block. In addition to sand, sediment and rust, a filter of this type will purify water from the smallest fractions of chlorine, clay, organic, and unpleasant odor.
3. Three-step filters - allow you to make the last stage in water purification, turning it into a quality drinking product. The reservoir contains three cartridges - sedimentary, an interlayer of activated carbon and an ion exchange element, which softens the water.

Advantages of operating the

device The popularity of the main filters has been achieved thanks to an impressive list of the advantages of using them. Let's consider each of them in more detail:

1. Essential improvement of taste qualities of water that is provided by complex clearing from various kinds of impurities and microorganisms.
2. Extension of service life of home appliances and pipelines. The presence of such filters contributes to the proper operation of washing machines, dishwashers, water heaters and existing sanitary ware.
3. Installation of such a device will enable to consume clean water and, accordingly, to preserve the health of the user.
4. Practicality of use, due to small dimensions and ease of operation.
5. In such devices it is possible to use replaceable cartridges that are oriented to protection against a certain type of impurities: softening of water, conditioning of water with activated carbon, lowering of iron level and purification from chlorine.

Disadvantages of installing the

filter Before you buy a water filter, you should also note some disadvantages of using them. These include the following features:

• need to manually clean the mesh cartridges as needed;
• install the filter on its own will not succeed. For this it is necessary to invite qualified plumbers;
• in case the device needs to be installed on a countryside site, there is a need for the services of specialists in drilling wells.

But despite all the nuances of installation and operation of the main filter, the positive effect of its application significantly exceeds any disadvantage.

In addition, choosing the main water filter, you should focus on the following indicators:

1. On which highway the device will be installed - hot or cold.
2. Technological capabilities of the filter.
3. Physicochemical indicators of water.
4. Reputation and reliability of the manufacturer.

Selecting the device by cartridge

The trunk filters are equipped with cartridges that provide the main function of the device - water filtration. Specialists subdivide them into the following types:

1. Granular cartridge with an activated carbon layer - this device is used to eliminate chlorine, organic, heavy metal, and unpleasant odor fractions. The advantage of using it is a sufficiently high degree of filtration. However, the flow rate of the water flow of this cartridge is not high.
2. Cartridge coal briquetted - cleans water from small fractions and chemical suspensions, as well as bacteria Cryptosporidium and Giardia. This type of cartridge filters water at high speed, but the degree of purification is weak.
3. Cartridge with polyphosphate loading for protection against scale. This type of filter element serves to protect the integrity of household appliances.
4. Cartridge that softens water by removing salt and hardness from it.
5. A mechanical impact cartridge that helps remove sand, rust, etc. from the water.

mainfilter manufacturers When selecting a main filter, attention should be paid to the manufacturer's rating and reputation. Today such products are offered by such producers as: Atoll, Aquafor, Opera, Biq Blue, Geyser, Bosporus, Barrier, Source Bio. Let's consider in more detail the features of the products of the most popular brands:

1. The cleaning devices "Geyser Typhoon" are versatile. Such filters are designed to purify water on both cold and hot lines. The replaceable cartridge is capable to clear water from ions of iron, salt, mineral oil, heavy metals, smells, mechanical impurities, and also to lower the coefficient of rigidity.
2. The reliability of German company Honeywell filters has been appreciated by consumers around the world. The device effectively copes with the cleaning of domestic water from large mechanical fractions and has no equal in efficiency of mechanical cleaning. In addition, the cartridges are equipped with a stainless steel mesh, which, if necessary, can be washed independently. In addition, Honeywell filters protect household appliances from pressure drops in the main. Such a main water filter costs a little more than analogues, but high quality of products will ensure a long service life.
3. Filters produced by the company "Aquaphor" are compact sorption cleaners that will give you the opportunity to consume water completely cleaned of harmful substances, chemical impurities and even unpleasant odor.

Cost of cleaning filters

Regarding price boundaries for main filters - they can vary considerably. The cost of appliances for cold water, usually starts at $ 50.00, and for hot - $ 120.00.This difference in price is due to the fact that devices designed for water purification on the hot line operate in more difficult conditions. Consequently, they are manufactured using a high-tech method with high quality requirements. The maximum cost of filters can reach $ 1000.00.

Independent installation of the main filter

In this process, one should take into account an important point - filters that are designed for cold water should not be used for cleaning hot. Different materials are used to produce these two types of the device. Therefore, the device for cold water can not withstand the aggressive effects of hot. But you can install the opposite. The presence of such a filter will provide an opportunity to protect yourself from the entry of rust, sand and chemical suspensions with the flow of water, and also eliminate the turbidity of the water.

Before installing the filter yourself, it is necessary to take into account a number of important factors:

1. For the convenience of further operation, during the installation of the filter, it is necessary to provide a tap from the filter flask and a ball valve to cut off the flow.
2. Also it is necessary to take into account that the cartridge is removable and it will have to be changed with some periodicity. For this reason, the filter should be located in an accessible location. Using the bracket, the device can be mounted on a wall.
3. When installing the main unit, it must be remembered that a coarse filter must first be mounted, and secondly, a thin filter.

Instructions on how you can assemble the filter yourself are shown on the video:

Replacing the

cartridge To replace the used cartridge, proceed as follows:

1. First turn off the water supply.
2. Next, the key that is attached to the cleaning device, it is necessary to unscrew the flask in accordance with the instructions.
3. Take out the used cartridge and put a new one.
4. Assemble the device to its original state.

Cartridges, in their overwhelming majority, are disposable. They are not provided for repeated use and at the end of their service life can not be restored.
