Reverse Osmosis Replacement Cartridges – RO Filter Cartridges Australia
Reverse Osmosis Replacement Cartridges — Awesome Water Filters Australia
Keep your reverse osmosis system performing at its best with genuine RO replacement cartridges from Awesome Water Filters. RO systems use multiple filter stages to deliver up to 99% contaminant removal — and each stage needs to be replaced on schedule to maintain that performance. This collection covers pre-filters, post-filters and RO membranes for compatible Awesome Water RO systems.
Why Replace RO Cartridges on Schedule?
- Clogged pre-filters reduce flow and put extra strain on the RO membrane, shortening its life
- An exhausted post-filter allows taste and odour to return to your purified water
- A degraded RO membrane reduces contaminant rejection rates — including fluoride, heavy metals and dissolved solids
- Regular replacement maintains the up-to-99% contaminant removal your system was designed to deliver
RO Cartridge Replacement Schedule
- Sediment pre-filter: every 6–12 months
- Carbon block pre-filter: every 6–12 months
- RO membrane (TFC): every 2–3 years depending on water quality and usage
- Post-carbon filter: every 6–12 months
- Alkaline/remineralisation stage (where fitted): every 12 months
Replace sooner if you notice a drop in flow, a change in taste, or if your TDS meter shows rising dissolved solids in the output water. Use our Replacement Filter Cartridges Guide for full intervals.

FAQs
- How do I know which RO cartridge fits my system? Match by stage (pre-filter, membrane, post-filter) and cartridge size. Check your system manual or the product listing for compatibility. If unsure, contact us with your system model and we’ll help confirm the right cartridge.
- How often should I replace the RO membrane? Every 2–3 years for typical household use. Replace sooner if your TDS meter shows rising dissolved solids in the output water, or if flow drops significantly.
- What happens if I don’t replace the pre-filters on time? Clogged pre-filters reduce flow and allow chlorine to reach the RO membrane, which can permanently damage it. Replacing pre-filters on schedule protects your membrane investment.
- Do I need a plumber to replace RO cartridges? Most RO cartridge changes are DIY-friendly using the quick-change fittings on compatible systems. If you’re unsure, see our professional installation via Airtasker.
- What is a TFC membrane? TFC stands for Thin Film Composite — the industry-standard RO membrane material with a pore size of 0.0005 microns, capable of removing up to 99% of dissolved contaminants including fluoride, heavy metals, bacteria and viruses.
