Everyone knows that the source of many serious diseases lies in the constant use of poor-quality tap water. To ensure full compliance of drinking water with the established standards and the needs of the human body, it is necessary to reconstruct water treatment facilities, replace most of the water and sewerage pipeline, and carry out a set of measures to reduce the level of pollution in waste water.
Solving such complex problems requires an integrated approach, significant investment and, of course, time. An exit from the developed situation becomes purchase of the stationary filter for water treating. What are water purifiers, and what parameters and characteristics should I pay attention to when buying? This we will discuss in the article.

Filter for water purification: whim or need?
The water entering our apartments from the municipal water supply system, often does not comply with the norms for the content of sodium, iron and other elements of the periodic table, the level of water hardness has been considerably exceeded. Many water users are trying to solve the problem of drinking water purification by various radical methods, at times very ineffective. For example, boiling water softens only slightly, and prolonged - and at all harmful. Defending, filtering mechanically, sorption - none of these popular methods can effectively cope with the preparation of drinking water for use. When heated, water forms calcium carbonate, which, being an insoluble compound, settles on the walls of the kettle in the form of a scale that is familiar to us, and the residual hardness is eliminated exclusively by means of special devices. Is there a way out of this situation? Certainly! And this is buying a household filter.
Choose a filter for water treatment
The modern market offers water users a lot of different models of modern water purifiers with different levels and technologies of cleaning, technical characteristics, installation methods and duration of use. Therefore, to bought your device has successfully operated and constantly please you delicious, and most importantly, useful water, examine the filter classification, understand their intricacies and peculiarities of work, identify their needs and match them with their own financial resources.
Filter-pitcher
The filter-jug is the simplest design: the device contains 2 compartments (upper and lower), with a replaceable filtration system fixed between them. Water is poured into the upper compartment and, passing through the filter, is cleaned and enters the lower compartment. The composition of the filter cartridge traditionally includes only activated carbon and ion-exchange resin, which removes rust, chlorine, dissolved iron, some impurities and a small amount of organic compounds from the water. Low productivity, satisfactory water purification, the need for frequent replacement of the filter cartridge and low cost - these are perhaps the main characteristics of such devices.
Instantaneous water purifier
Better water purification is possible with stationary flow filters installed under the sink. The flow-through device is equipped with a separate tap, which will always supply you with clean drinking water, which is quite suitable for consumption, and has several levels of purification, each of which has its own technology.
- In the first stage A rough mechanical cleaning is carried out, thanks to which flakes of rust, impurities and large particles are successfully caught.
- In the next stage ion-exchange cleaning is carried out, by which heavy metals, hardness salts, heavy metals, iron dissolved in water, and others are retained.
- At the final stage there is a fine cleaning with activated carbon, capable of effectively purifying water from those impurities that the previous two filters failed to handle. Flowing instruments have a high productivity - 3-4 l / min, which means that you can quickly get clean water, suitable for use.
Reverse Osmosis Filter
The most high-tech and efficient water treatment systems are water purifiers based on reverse osmosis technology, through which water seeps through a special porous membrane. Its pores are so small that only molecules of water are passed, retaining metals and harmful impurities. Water at the output of the reverse osmosis system is clean, it can be said, distilled. The reverse osmosis device is expensive, but the unique opportunity to successfully obtain the purest water justifies all the costs of buying and installing.
Tips for choosing a filter
1. Before buying a filter you need to determine the composition of impurities, from which you wish to get rid. To do this, you should contact the laboratory, which specializes in establishing the chemical composition of water. The measurement of the average daily volume of water consumed will help you determine the optimum performance of the device.
2. An important factor that influences the choice of this or that filtration system will be the fabrication material. Since it directly contacts the water consumed, it must prevent the reproduction of microorganisms and be absolutely safe for the human body. Looking at yourself a stationary device with a separate crane, pay attention to the strength of the materials of the water purifier, since the device is connected to an active water pipe and undergoes constant pressure.
3. Of no less importance is the productivity of the filter and the efficiency of cleaning - the percentage of removal of all kinds of impurities from the water. These data can be found in the passport of the device. In addition, the household filter should reduce the concentration of impurities harmful to health in normal operation. Harmful impurities must be removed irreversibly, excluding the possibility of secondary entry into water even after the expiry date of the water purifier or non-compliance with individual operating conditions.
4. All declared operational characteristics of the device must comply with the design features and dimensions of the device. For example, it's foolish to hope that a filter the size of a cup will function forever.
5. The modern market is saturated with all kinds of domestic and foreign manufacturers of water purification devices. Among them are companies specializing in the development, creation and improvement of household filters - Aquaphor, Barrier, and Geyser, but there are also manufacturers for whom these devices are "random."
