FilterPro exclusive thick deep profile FX4 medium filter foams. Single foam.

Profile cut for maximum surface area which ensures that maintenance intervals are kept to a minimum and suspended particles are removed most efficiently. Much more effective than standard Fulval flat foams as the initial contact area is approx. 60% more than flat foams.

The foams are slightly too long so trim them to suit (some people like them very tight).

Medium foam is approx. 30ppi and 2" (50mm) thick.
