Finest-Filters filter wool provides excellent mechanical filtration in aquarium and pond filters alike. This filter wool works by electrostatic attraction, so the waste particles are attached to the synthetic fibres like a magnet, which is very effective at removing particulate waste from the water column.

Our Filter Wool sheets are available in two different thicknesses. Please ensure you have selected the correct desired thickness. This product contains:

3 sheets of size 18” x 12” (inches)

Thickness of this Filter Wool: 30mm (approx)

Our filter wool is totally aquatic safe, and is not treated with any chemicals, so it is guaranteed to not harm your fish. We have been using this in our tanks for many years with great results.

This product is packaged in a grip seal bag to keep the remaining product clean.
