Filter Foams have a very precise open pore structure. PPI is pores per inch, so the higher the PPI, the finer the particles that will be filtered.
This is a general use filter foam which is useful for pond filters as well as vacuum filters, mower filters and similar. An advantage of filter foam is that it does not absorb water
