Frame pools with cartridge filter

Cartridge

— in accordance with the name, such filters use special cartridges with filter elements in the form of membranes made of polymer material. Cartridges are made disposable; when dirty and worn out, such an element must be replaced. This is associated with additional costs, but consumables are inexpensive, and initially cartridge filters are cheaper than sand filters. Another advantage is their relatively compact size. The operating speed of cartridges is lower than that of sand systems, but such a filter can still be made quite productive even for a fairly large volume of water. Thanks to all this, most modern frame pools are equipped with cartridge devices.
