Fit guarantee. If these don't fit your CHF 15" × 4.5" housings on arrival, we'll make it right — full refund or exchange, no questions asked.
Sealed polypropylene cartridge, 5 micron. Catches sand, rust and dirt before they reach the later stages.
Stage 2 · ResinResin media refillPW-M-RES-2500
A 2.5 L resealable bag of certified ion exchange resin — one full fill, bringing your housing to the correct fill line (not the top: resin needs headspace to work). Softens your water by taking out calcium and magnesium, poured into your existing CHF resin housing — built to be refilled, not thrown away.
Sealed cartridge, 5 micron. Reduces chlorine, taste and odour.
The two sealed cartridges drop straight into your housings, and the resin is a quick refill. Step-by-step instructions come with every set. In the same honest spirit: we only list certifications we can document — the sediment and carbon cartridges are quality-checked but don't carry independent certifications.
Why these filters
Independently designed for the CHF 15" format — built to fit the 15" × 4.5" housings used in CHF systems, with dimensions checked against the real thing, not just a spec sheet.
Fill volume physically validated — the 2.5 L resin fill was measured in an actual housing to the fill line. One bag really is one full fill.
Checked and dispatched from Perth — every order goes out within 1–2 business days, and if anything's off, you call and get Joe, not a call centre.
No contract, no lock-in — buy when your filters need changing, not when a schedule says so.

In their own words
We found ProperWater after we received our renewal quote for filters, which was exorbitant. Easy install and great service. We hadn't installed the system and weren't in a position to pay $498.
George K · Peakhurst, NSW
I didn't realise I had an option for replacement filters, but did some searching and found ProperWater. Super easy to deal with, great quality filters and unbelievable value.
Tim M · Adelaide, SA
I'd wanted to replace the resin early, but it wasn't my renewal time so I couldn't. It's my system — I should be able to choose. I also like car detailing, so the extra resin was perfect.
Daniel · Beckenham, WA
We recently switched to ProperWater replacement filters for our CHF system because we simply couldn't justify the $548 price for the CHF replacements. The ProperWater filters fit perfectly, the water tastes great, and we're really happy with the quality. Excellent value and we'd happily recommend them.

Common questions
Are these as good as genuine CHF filters?
Honest answer: they're not genuine CHF cartridges, and we don't claim to be — they're our own PW Series, independently designed for the same 15" × 4.5" format CHF systems use. What we can stand behind: certified resin media (see above), a physically validated fill volume, and a fit guarantee if anything doesn't fit on arrival. We don't publish performance comparisons we can't document.
Will they fit my CHF system?
This set fits CHF systems that use the 15" × 4.5" housings. Not sure which system you have? Use the identification guide — it takes about a minute.
How often do I need to change them?
Typically every 6–12 months, depending on your water and usage — most households land on a yearly rhythm. Step-by-step instructions come in the box, and you can join the free filter-change reminder list so it's never on you to remember.
Resin softening — what it does
Reduces the calcium and magnesium behind limescale, giving noticeably softer water on skin, hair and glassware. The resin is refilled roughly once a year as the media exhausts, depending on your water and usage.
Not sure if resin or NAC suits you?
Resin (this set) softens water by removing hardness minerals — best if you want that soft-water feel. Refilled yearly. NAC scale prevention conditions water so scale can't form while keeping minerals in — best for set-and-forget protection.
