What are the filters for water purification for the home

The quality of the water in the water supply system is far from international standards. Its consumption can be called an extreme occupation, because of which there is a likelihood of serious damage to health. High-quality water filters will help to avoid problems, which are not so easy to choose, as the range is wide enough.

Household Water Filters

general information

Most water supply stations in large settlements guarantee the quality of tap water. But the liquid before entering the population passes through kilometers of rusty and worn pipes. On the way to the crane, a large amount of harmful substances gets into it.

Even if the water does not cause any suspicion to taste, this does not mean that it is safe. To determine the content of impurities, you should submit a sample to the sanitary-epidemiological service.

You can also roughly determine the quality of drinking water at home:

Modern water filters

  1. If after some time after cleaning the kettle a layer of scale appears in it, and after making tea on the surface there is a film, this means that the water is too hard: it contains a large amount of salts.
  2. Putrid taste. Hydrogen sulfide is present in the liquid.
  3. After washing, the clothes have a gray tint. This means that there are heavy metals in the water.

Some people buy bottled water, but most examinations show that such a liquid does not always comply with sanitary standards. A list of such manufacturers can be found on the official website of Roskontrol. This is one of the reasons why many are starting to buy household water filters.

Water filter in the form of a jug

Jug Filter

The simplest and most popular filter for water treatment is a jug with a replaceable cartridge. It cleans the fluid mechanically and chemically.

Cartridge filling may vary depending on who the filter jug ​​manufacturer is, but the technology is always the same. After filling the tank, the liquid passes through the replaceable element and enters the bowl.

The main substances used in water purifiers:

  1. Activated carbon is the most common filler.
  2. Zeolite. Absorbs ammonia.
  3. Shungite. Removes chlorine.
  4. Ion exchange resin. Reduces stiffness.
  5. Antibactericidal additives. Silver ions are often used. Necessary to suppress the growth of bacteria.

The main advantage of the cleaner is its compactness and mobility. This device is easy to transport and place anywhere. Another plus is the affordable price.when compared with other types.

It also has a drawback - the low quality of cleaning. You will also have to quite often change the cartridges.

Flow options

From the list of devices for mechanical cleaning flow types are leading. There are several options for implementing this method. These include:

  • desktop;
  • nozzle on the mixer;
  • installation under the sink.

How to choose a water filter

Desktop is the easiest to use option. In such a system, replaceable cartridges are used, which are installed in a plastic case.

To clean, you need to wear a special nozzle on the tap and turn on low pressure. When the liquid has passed all degrees of purification, it will begin to flow from the 2 outlets of the cartridge.

Attachment on the crane. This is exactly the same technology, but made in a different form. The filter has a universal mount, so it can be installed on any mixer. The big advantage is space saving.Installation can be done independently without causing plumbing.

The filtration system under the sink requires free space and a separate tap. Such a device is connected directly to the water supply pipes. Modular cleaners are carried out in a console form with plastic flasks. They are located in the direction of the fluid in series. Each subsequent cartridge has a finer degree of cleaning.

Ultrafiltration

Water purifiers

Although it has a rather loud name, the ultrafilter is a subspecies of flowing devices and is also located under the sink. It has several series-connected flasks that perform a different task. This is a cross between reverse osmosis and a flow-through type of treatment.

The main feature is the presence of a membrane with small pores. It is located in one of the cartridges. The holes have a size of from 0.01 to 0.1 microns.

Water enters the element after all other degrees of purification have passed. The pore size does not allow even some bacteria to pass. This filter stops absolutely all mechanical particles. This type is able to disinfect a liquid without changing its mineral composition and chemical structure.
