The complete 3-stage replacement set for your Complete Home Filtration (CHF) system. Compatible with CHF 15" × 4.5" housings — free delivery Australia-wide. Every set includes: Sta ge 1 — Sediment filter (PW-F-1545C-PP5): sealed polypropylene cartridge, 5 micron. Reduces sand, rust and dirt. Stage 2 — Resin media refill (PW-M-RES-2500): resealable bag of NSF-grade ion exchange resin that softens your water by reducing calcium and magnesium — the hardness minerals. Pour into your existing CHF resin housing — designed to be refilled, not discarded. One bag is one complete refill. Stage 3 — Activated carbon block (PW-F-1545C-CTOC5): sealed cartridge, 5 micron. Reduces chlorine, taste and odour. Two sealed cartridges drop straight in, and the resin is a quick refill of your existing housing. Step-by-step instructions included. Resin softening — what it does: reduces the calcium and magnesium that cause limescale, giving you noticeably softer water on skin, hair and glassware. The resin is refilled about once a year as the media exhausts. Not sure if resin or NAC is right for you? Resin (this set): softens water by reducing hardness minerals. Best if you want that soft-water feel. Refilled yearly. NAC scale prevention: conditions water so scale can't form, while keeping the minerals in. Long-life and low-maintenance. Best for set-and-forget scale protection. Compatible with Complete Home Filtration (CHF) systems. ProperWater is independent and not affiliated with CHF. Show more
