Match the part code on your filter sticker to identify what you had last time, then continue to the shop to reorder. Australia-wide shipping, Perth metro installation available.
A whole-home filter sits between your mains water supply and the rest of your house. Water enters the first housing, flows through each stage in series, then exits to feed every tap, shower and appliance in your home.
Each housing holds one filter or refill. Water flows through three stages in series — what each stage does depends on your setup. Together they treat the water before it reaches the rest of your home.
Every Proper Water filter and refill has a part code printed on the sticker — usually starting with PW-. Find yours below and continue to the shop. Not sure? Use the picker further down or send us a photo.
If you can't see the part code on your filter, this short picker will point you to the right product.
Snap a photo of your filter housing or the sticker on your old cartridge and email it through — we'll identify it and confirm what you need within 24 hours.
