Refillable Media Casing Water Filtration 20″x 4.5″, Suit Big Blue 4-17, BPA Free

Refillable Media Casing For Water Filtration 20″ x 4.5″ | Suit Big Blue 4-17
Size: 20″ x 4.5″
Suits customers needing refillable cartridges for Carbon, Calcite, Sand, Resin & more.
This cartridge is a TRUE refillable cartridge with SCREW OFF endcaps – not glued lids.
This unique canister allows both ends to screw off so the pads and the sediment can be replaced or cleaned.
All other canisters of this size do not permit access to the top filter plug which is what blocks up to render the cartridge unusable.

There are many on the market but few are truly re-useable because they have glue type seals. 

Look carefully next time you do search for re-fillable canisters, most do not have screw off end caps.

Very popular with beer brewers.
