The goal of purifying water which is supposed to be drunk or to be used for preparing meals, it is worth to use pitchers with filters.

Kinds of filters

We can distinguish the following types of filters:

– the polypropylene filter – let’s note that the polypropylene cartridge is a mechanical filter. It allows  to remove sand, corrosion products, small suspensions, fats as well as impurities that are washed off the surface of hydraulic installations from the water. According to the warranty of this filter, it is recommended to mount it at the end of the series (according to the direction of water outflow). It is worth to install 2 filters – at the beginning and at the end of the series. It should be added that these filters are intended for mechanical filtration. They fit into every water installation. Importantly, it will need to be replaced when the filter is dirty,

– the filter with an active carbon- it allows to effectively get rid of chlorine and its compounds and organic pollutants. What is more, it improves taste, color and the taste of water. Activated carbon filtration is recommended to precede mechanical filtration (using a polypropylene filter). It is worth to underline that a filter with an active carbon consists of highly active granulated carbon from coconut shells, which removes organic substances and chlorine compounds. This filter is supposed to be used for highly chlorinated water.

– ion exchange resin filter- it allows to soften water by removing calcium and magnesium ions which make water hard. Hard water causes the formation of scale on elements of kettles, heating washing machines.
