foam set, suitable for the Oase Biotec 5/10/30 pond filters.
These Coarse and Fine filter foams are available in a range
combinations. Please see the drop down menu above to make your choice of number

Our replacement foam filters are made from high quality
reticulated foam, in the same specification and colour as the Oase original
filters.
Unlike other sellers, we do not substitute the red foam for
cheaper quality green foams! These foams are made to the same specification and
colour as the original filters!
The size of these foams is approx 25cm x 25cm x 8cm. They have a slit through the centre.
