What is inside the household water filter

“It is not beer that kills people, water destroys people,” Vyacheslav Innocent sings in the beloved musical comedy. And when it comes to dirty tap water, this is far from an exaggeration today. The obvious solution is a household water filter.



But there are nuances here. Getting really tasty and clean water will help you simple rules. And to stick to them was easier, we will tell you how it works and what is a replaceable filter cartridge.





In conclusion, we will introduce readers to the test of the most common filter jugs. The video will let you know which models cope with their tasks better than others, and will clearly demonstrate why this happens.

Preparation for the first use Drinking water from the tap is possible, but hardly necessary. Even a schoolboy knows this today. The filter jug purifies tap water from active chlorine, heavy metals, petroleum products and other contaminants. It also eliminates unpleasant odors and improves the taste of water.



Before the first use, all the details of the filter (funnel, jug and cover) must be washed with a weak soap solution and rinsed with running water. The new cartridge according to the instructions must be immersed in cold water for 10 minutes before installation.



Then you need to insert the cartridge into the funnel socket and fix it with a threaded (or other) connection. The first two portions of purified water should be drained, as a small amount of coal dust may appear in them.

Filter jug is suitable for cleaning only cold water (up to 35 degrees). It is unacceptable to keep the filter dry for a long time, leave it under direct sunlight, keep filtered water in a jug for more than 2 days.



If you plan a long break from work, remove the cartridge from the filter. Then wrap in a plastic bag and leave it in the fridge. When restarting, repeat the same steps as during the initial installation.

Water filters, even the best ones, cannot purify water indefinitely. Each of them has its own resource. As a rule, the life of the cassette in average conditions is 200-350 liters. For a family of 3 people, we get 25-50 days of use.



But it's in theory. In real life, the duration of the filter is significantly affected by the amount of impurities in tap water. It (duration) can be less and more than indicated in the passport. So you will have to navigate by visible signs.

It is time to change the cartridge when the taste or color of the liquid has changed (the result of a decrease in filtering ability). If purified water is boiled, scaling on dishes is formed (the filter does not cope with the removal of calcium and magnesium salts).

Another sign is that the filter does not pass water at all or its pressure has decreased significantly. But it's not that simple. Not to filter the water may well be a new replacement module. This is often due to air traffic.

Cold tap water contains air bubbles that increase in size as water passes through a module in a warm room. Such a cartridge should be placed horizontally in cold water and shaken several times. There are situations when the net is clogged with dirt or rust at the entrance to the filter (it is easy to clean with your hands).



On the other hand, if the cartridge passes water well, this does not mean that it has not yet exhausted its resource. In most bulk cartridges (with the exception of "Aquafor", as we will see below) there is a channel effect.

This means that channels can form in the filler array over time, through which water will pass without coming into contact with the sorbent and without being purified. Without replacement, this filter will do more harm than good.

To make sure with your own eyes what a household filter for water purification consists of, it must be cut (it must be done carefully and with a cartridge that has spent its life).



The video shows that most of the volume is occupied by a filler consisting of two fractions.



Black pellets are activated charcoal that contains a large number of pores and can trap dirt and organic compounds. Light pellets are particles of ion exchange resin that can absorb salts, metal ions, and other complex contaminants from water.





In the filters "Aquafor" another type of filler is used - fiber sorbent Aqualene. It absorbs impurities of heavy metals and, thanks to its shape, firmly binds the filler array, preventing channels from forming in it.

Due to this, the contents of the cartridge "Aquafor" keeps the shape and provides better, according to the results of the test, filtering impurities.





As you can see, installing water filters has become a vital necessity. Such filtering systems reliably protect us from various contaminants. However, it is worth carefully approaching the question of choosing a suitable solution, as well as changing cartridges in a timely manner.
