Installation & Maintenance

Most under sink water filters connect to your existing cold water line and include a dedicated chrome tap that mounts beside your main tap. No major plumbing work is required for most models, though we recommend a licensed plumber for a clean, compliant installation. Need help arranging installation? See our professional installation via Airtasker. Cartridge replacement is typically required every 6–12 months depending on usage and water quality.

Frequently Asked Questions

• How does an under sink water filter work? It connects to your cold water supply line and passes water through one or more filter cartridges before delivering it through a dedicated tap. Each stage removes specific contaminants — sediment, bacteria, chlorine, fluoride, heavy metals — depending on the system.
• Do I need a plumber? Most systems are DIY-friendly, but we recommend a licensed plumber for a clean, compliant installation, especially if adding a new tap hole. See our Airtasker installation service.
• What contaminants does an under sink filter remove? Depending on the system: chlorine, chloramines, sediment, bacteria, cysts, heavy metals, fluoride, pesticides and organic chemicals. Check each product listing for specific performance data.
• How often do I replace the cartridge? Most cartridges last 6–12 months. Replace sooner if you notice a drop in flow rate or a change in taste or odour. See our Replacement Filter Cartridges Guide.
• Is an under sink filter better than a benchtop filter? Under sink filters are more permanent, keep your bench clear and offer higher flow rates. Benchtop filters are better for renters or those wanting a portable, no-plumbing solution.
• Can I use an under sink filter with tank or bore water? Yes — our ceramic systems are suitable for tank, river, bore and municipal water sources. Always check the individual product listing for compatibility.
