CHF Replacement Filter Set — Complete 3-Stage

The complete 3-stage replacement set for your Complete Home Filtration (CHF) system. Compatible with CHF 15" × 4.5" housings — ships Australia-wide.

Every set includes:

• Stage 1 — Sediment filter (PW-F-1545C-PP5): sealed polypropylene cartridge, 5 micron. Removes sand, rust and dirt.
• Stage 2 — Resin media refill (PW-M-RES-1500): resealable bag of NSF-grade ion exchange resin that softens your water by removing calcium and magnesium. Pour into your existing CHF resin housing — designed to be refilled, not discarded.
• 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: removes 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 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 the minerals in. Long-life and low-maintenance. Best for set-and-forget scale protection.
