Will it fit?
Match the 10″ × 4.5″ format.
Compare your current cartridge’s overall length, widest diameter and end seals. 10″ × 4.5″ is a nominal format, so check the cartridge itself before ordering.

Measured it and still not sure?
Send a photo of the cartridge beside a tape measure and we'll tell you which size it is.
Call 0474 189 347 or email sales@homefiltrationsystems.com.
Nominal sizes vary a little between makers, so match the measurement rather than the label. What we can't tell you is how ours compares to a cartridge we didn't make and haven't tested, or whether a replacement affects your housing's own warranty; that one is between you and its manufacturer.
