What types of protective filters are available? And which is the right one for me?

Depending on requirements, DIN-DVGW-tested cartridge filters, backwash protective filters or domestic water filtration stations are used.

Cartridge filters are the simplest variant. As the name suggests: According to the EN 806-5 A standard, the filter insert of these filters must be replaced at least every six months. During the replacement process, the water is shut off. The water supply is thus briefly interrupted.

With backwash protective filters, there is no need to replace the filter insert. Although these protective filters are somewhat more expensive to purchase, you can easily remove particles from the screen yourself. The water supply is not interrupted. The standard also stipulates an interval of six months for backwashing. JUDO recommends that such filter cleaning should be carried out every two months.

Automatic backwash protective filters are available for more comfort. Such a filter carries out the backwashing independently – as owner you have even less effort. An automatic version is also suitable for apartment buildings, as experience has shown that protective filters are often neglected there.

If backwash protective filters are equipped with an additional pressure reducer, they are referred to as a domestic water filtration station. The pressure reducer compensates for pressure fluctuations and thus protects household appliances and fittings. In addition, a domestic water station can also reduce water consumption.
