How often should I change them?

For the best possible water: change every 6 months.

That’s when taste is cleanest and flow is happiest. Absolute longest: 12 months—or sooner if taste drifts or flow drops.

FAQs

Are these made by Puretec?
No. These are compatible replacement cartridges supplied by Filtration Station (Premium Davey or Aftermarket). 

Do I need O-rings and lubricant?
Most households only need the cartridges. If your O-rings are worn, we can point you to the right sizes.

Mains or rain/tank?
These sets are optimised for mains taste/odour + chlorine reduction. For rain/tank stacks, see our rain/tank kits.
