Water filters capture mechanical impurities as water runs through the filter body. The water filter ensures a continuous supply of filtered water. A fine filter reduces the amount of foreign particles in the water, such as fragments of rust or grains of sand. Dirt settled at the bottom of the filter container can then be easily removed. A water filter most often consists of a housing and a filter insert, which may not always be included in the package. Filters can be divided according to the type of water use into house filters for drinking water, rainwater filters and flange filters.
Home filters for drinking water include cold water filters and hot water filters. In domestic filters, cleaning is mostly done by backwashing, while the need to change the insert is eliminated, instead you simply drain the water with trapped impurities once in a while. This kind of drinking water filter is suitable for every supply water pipe of a family house and apartment and is also used as a filter for water from a well. Some domestic water filters can be extended with an automatic backwash unit that cleans the filter at a pre-set times for you.
Rainwater filters are used to treat and purify rainwater for simple systems where drinking water is not required, such as watering, flushing, washing and other.
Flanged water filters are used for cleaning non-aggressive liquids supplied to pipelines or fittings. They are intended for industrial use and serve primarily to capture coarser dirt.
During water filtration, the water filter retains mechanical impurities as the water flows under pressure through the filter body. The water filter consists of a filter housing and a filter element (not always included).
In domestic filters the cleaning is done by backwashing, then there is no need to change the cartridge, just to drain the water with trapped impurities by tap in the lower part. In addition, the domestic water filter can be easily fitted with a pressure limiter. It is a water filter that is suitable for the supply piping of each family house or apartment.
Flange filters are used for cleaning of non-aggressive liquids supplied to pipes or fittings. The stainless steel filter element is cleaned at zero pressure after unscrewing the lower cap according to the instructions. It is used mainly to catch coarser impurities. With this type of mechanical filters, however, it is not possible to trap dissolved substances, for their possible removal it is possible to use an activated carbon filter, which works on a slightly different principle.
