Common questions
How do I know when a cartridge needs changing?
Follow the recommended schedule, and change cartridges sooner if you notice lower flow, a drop on the pressure gauge, or a return of chlorine taste or smell.
Do I need to use your cartridges?
Our cartridges are matched to our housings and tested together. Using genuine cartridges on schedule also keeps your system's warranty valid.
How often do I need to replace cartridges?
Most sediment and carbon cartridges last 6 to 12 months, benchtop and shower cartridges about 6 months, and reverse osmosis membranes 2 to 3 years. Homes with more sediment or higher water use may need more frequent changes. Each product page lists its schedule.
