Filter Insert (Empty)

21, 30 & 40" Refillable Filter Cartridge can be filled with any filtration media of your choice such as DI Resin , Polyphosphate Crystals, Activated Carbon,Ceramic Balls, etc...and when it is time to change filters you can simply remove this cartridge from your filter housing , empty out your media and refill with new media and simply insert the cartridge back into the housing.

You can insert any water filtration media into the refillable cartridge

Used a lot by people who filter plenty of water for either residential or aquatic use (and many more) for insertion of various filtration media , as they can buy a bag of filtration media and replace the media themselves instead of buying disposable filters.
