Imagine Filter Cartridges for Penquin
A new design in filter cartridges, the Imagine Bio 3 disposable filter cartridge is the perfect replacement cartridge for your Penquin Power Filter. This 3 stage cartridge provides mechanical, chemical and biological filtering in one easy to change packet. The special design of the filter pack keeps the carbon distributed throughout the pack thus eliminating the "Tea bag" effect found in other cartridges.
