Measure these two.

Measure the cartridge you're replacing, not its housing.

A filter cartridge with two measurements marked: A, overall length end to end including caps or connectors; B, widest outside diameter.
A Overall length — end to end, including caps or connectors
B Outer diameter — at the widest point of the body

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.

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.

FAQ

Before you order

Talk to someone

Need help choosing? Call 0474 189 347.

Will it fit my housing?

It uses the 10″ × 4.5″ nominal cartridge format. Compare the actual length, diameter and end seals with your current cartridge before ordering.

When should I replace it?

Plan to replace it every 6–12 months. Water quality and use can require earlier changes.

Will it reduce scale?

This carbon block targets chlorine taste and odour. Dissolved hardness needs a suitable resin or softening stage.
