Common Questions

CHF replacement filter
questions, answered.

PW Series filters are manufactured to the standard 15" × 4.5" Big Blue format used in CHF 15" systems. If your system uses 15" Big Blue housings, PW Series will fit. If you're unsure of your model, send us a photo and we'll confirm before you order — no guessing.
CHF recommends annual replacement. Visible signs include reduced water pressure, returning chlorine taste or smell, or a heavily discoloured sediment filter. In Perth's inner-north suburbs — with TDS above 500 mg/L — some households find 9-month replacement is better, particularly for the sediment stage.
Filter cartridge replacement on an existing system (not connecting to water supply) can typically be done yourself — it's a twist-out, twist-in process. You don't need a licensed plumber just to swap cartridges. We include instructions with every order. If you'd prefer someone else to do it, our Perth install option ($60) covers this.
Initially we'll be selling the complete 3-filter set at $195. Individual filters will be available as the range expands. Register your interest and we'll let you know — if you only need a specific stage, mention it in your registration and we'll sort something out.
We ship Australia-wide. Shipping rates will be calculated at checkout based on your location. We're working on free shipping for full 3-filter sets — register your interest and we'll confirm the exact rates when stock arrives.
Under Australian Consumer Law (ACL), a supplier cannot void your warranty simply because you used a compatible third-party consumable. This is a well-established consumer right. If CHF attempts to void a warranty claim solely on the basis of filter brand — and the filters are dimensionally compatible and correctly installed — they would likely be acting contrary to ACL. We recommend keeping records of your filter purchases and installation dates. This is not legal advice — consult a solicitor if you have a specific warranty dispute.

"Complete Home Filtration," "CHF," and "CHF-6000" are used solely to indicate product compatibility and identify the systems these filters are designed to fit.
