Filters & Cartridges

Replacement water filter cartridges

All drinking water systems that filter your water will require their water filter cartridges to be replaced when they become exhausted.

You can either come to our showroom to collect your replacement filter cartridge or we can post it directly to your home. Call us today.

Replacing your filter cartridge

WARNING To avoid injury and/or property damage, system must be depressurised before attempting to change cartridges. 

See Step 1 for proper procedure. 

If you are unsure about any part of the cartridge replacement procedure, contact us for assistance.

If you are outside the South West of England, find the dealer nearest you using Kinetico’s website. 

This cartridge (Part No. 9306B) is designed for the reduction of taste, odour, and aesthetic chlorine. 

This replacement component is for use exclusively in the Kinetico Drinking Water Filter Model 7000 and as a postfilter in Drinking Water Systems.


In systems with MACguard (Drinking Water Filter Model 7000 & 7500) The MACguard filter automatically shuts off/reduces flow to a fine trickle after 1,850 litres (approx. 500 gallons) of water have been processed. 

Cartridge replacement is required to restore water flow. 

In Drinking Water Systems without MACguard you should replace your prefilter and postfilter cartridges at least once per year. Installation must comply all applicable laws and regulations.
