Dense filter foam for Pat Mini filter by Aquael, contains a dense foam cartridge for the Aquael Pat Mini Filter . These filter foams are placed on the lower part of the filter. They fit perfectly and are very easy to insert. In the same format as the original filter foam, this replacement block of dense foam from the Pat Mini offers excellent mechanical and biological filtration. Indeed, it retains residues and attacks waste thanks to the bacteria present in the foam. Depending on the use of the filter, the foams must be changed approximately every 4 weeks.
