Why Multi-Stage Cartridges Cost More — and Why They’re Worth It

Our 8-stage KDF cartridge combines ceramic, KDF media, activated carbon, and mineral stone stages in a single unit. A single cartridge does the work of 3–4 separate filters. At $50–$90 per cartridge replaced every 6–12 months, the annual cost is typically $50–$180 — far less than buying bottled water.

What Affects Cartridge Cost?

• Filter media: KDF media and ceramic are more expensive than basic carbon
• Capacity: high-capacity cartridges cost more upfront but last longer
• Brand: genuine cartridges from the original manufacturer are more reliable than generic alternatives
• Water hardness: in hard water areas (Perth, Adelaide), cartridges clog faster and need replacing more often

Buying Tips

• Buy genuine cartridges — generic alternatives may not meet the same filtration standards
• Keep a spare on hand so you can replace immediately when due
• Buy in bulk if your system uses the same cartridge type — we offer multi-packs in our replacement cartridge range
