Replacement Kits
Kits with all the cartridges you need for a full filter change, with or without a new UV lamp.
How to choose
- Find your system's brand and model. It's usually on a label on the housing, bracket or UV unit.
- No UV? Choose a filter kit. Have a UV system? Choose a lamp and filter kit so everything is changed together.
- Check the size and number of stages. Many kits come in 10" Jumbo and 20" Jumbo sizes, in 2-stage and 3-stage versions.
- Genuine or compatible? We stock genuine kits from brands like Davey and Waimana Water, and compatible kits for systems such as Puretec, Greenway and Trevoli.
Common questions
How often should I replace my filter kit?
Most kits are replaced every 6 to 12 months, depending on your water quality and usage. Some systems suggest every 6 months for best taste.
How often does the UV lamp need replacing?
Once a year. A lamp can still glow after 12 months but may no longer treat water reliably.
Will a compatible kit fit my system?
Each compatible kit lists the systems it fits. Match your system's model to the list on the product page.
Should I change the quartz sleeve too?
Clean the sleeve when you change the lamp. Replace it if it's scratched or cloudy.
