Main filters
Provide rough mechanical purification of water from sand, rust and silt.
Carbon cartridge pre-filters also remove chlorine, phenols, benzenes, heavy metals and pesticides from the water. After preliminary purification, the water becomes more transparent and gets rid of foreign odors, but remains undrinkable.
