Description
The Inline Shower Filter Cartridge is the replacement refill for inline shower filters fitted between the shower arm and head or hose. Over time the media inside a shower filter becomes saturated with chlorine and dirt and stops working. Changing the cartridge on schedule keeps your shower water filtered and your skin and hair protected.
When to replace the Inline Shower Filter Cartridge
- Every 3 to 6 months for a typical household
- Sooner if the chlorine smell returns during showers
- When water flow drops noticeably
- If the cartridge looks heavily discoloured
Homes using tank or tanker water with more sediment usually need more frequent changes.

Typical media inside
- KDF-55 process media for chlorine and some heavy metals
- Activated carbon for chlorine, taste and odour
- Calcium sulphite for chlorine reduction in hot water
- Ceramic and mineral beads
- PP cotton pre-filter to trap rust and sediment
Composition varies by filter model. Check that the cartridge matches your housing before ordering.
How to replace it
- Turn off the shower and unscrew the filter housing from the shower arm or hose.
- Open the housing and remove the old cartridge.
- Rinse the housing and insert the new cartridge in the correct direction.
- Close the housing, refit it and run water for 30 seconds to flush.
