What each filter does
| Filter | What it does |
|---|---|
| 5 micron polyspun sediment filter | Captures fine sediment, rust, and dirt — keeps water clear and protects the carbon block from loading too quickly. |
| 5 micron carbon block filter | Reduces chlorine, chemical tastes, and odours. The stage that makes the biggest difference to how your water tastes at every tap. |
Davey vs Waimana — which should I choose?
Both kits include the same two-cartridge configuration. The difference is the filter brand.
Davey filters carry WaterMark and AS/NZS 4020 certification — independently verified to perform as claimed. As Davey Master Dealers, we know the range and support it directly. Choose Davey if certified performance matters to you.
Waimana is our value option — solid, reliable filtration at a lower price point. Choose Waimana for baches, holiday homes, and rentals, or where budget matters more than certification.
How often to replace
Replace every 6 months for best taste and performance. 12 months is the maximum recommended interval. If chlorine taste returns or flow drops noticeably, replace before your scheduled interval.

Frequently asked questions
Will these fit my system?
Yes — this kit is matched to 10" Jumbo housings (10" x 4.5") and suits the Puretec WH2-30. It also fits equivalent 10" Big Blue Jumbo housings of the same size.
What's the difference between Davey and Waimana?
Both kits include the same two-cartridge configuration. Davey filters carry WaterMark and AS/NZS 4020 certification — independently tested and verified. Waimana is our value option, built to NZ standards at a lower price point. Choose based on your priorities and budget.
What does AS/NZS 4020 certification mean?
AS/NZS 4020 is the Australian and New Zealand standard for products in contact with drinking water. It confirms the filter materials are safe and that the filter performs as specified. It is independently verified, not a self-declaration.
How often do I replace the filters?
Every 6 months for best taste and performance. 12 months is the maximum. If you notice chlorine taste returning or flow dropping before your scheduled interval, replace early.
Are O-rings and lubricant included?
No — cartridges only. O-rings and lubricant are not included in this kit.
Can I replace the cartridges myself?
Yes. WH2 housings use a standard housing spanner. Shut off the water, unscrew the housing, swap the cartridge, and reinstall. No special tools needed beyond the spanner.
