Foam cartridge 9.5x9.5x50cm medium blue for existing filter system

The foam cartridges dispose of a large surface for the settlement and provide for an excellent mechanical and biological filtration. Suitable for nearly all cartridge filters with a casing tube up to a diameter of 32 mm and for the Cyprio Green Machine filter. They are resistant to ozone and oxygen and can be used up to 120°C.The low-weighted CFC-free recyclable foaming is used not only in garden pond filters but also in aquatics. The filter foam is distinguished by its durability and is absolutely neutral to water. There are no substances dispensed to the water. The dirt that accumulates on the outside of the cartridge automatically falls off as soon as the particles are too large. The dirt particles simply sink to the ground, leaving the cartridges hardly clogged.
