Whole-home vs under-sink water filters — which do you need?

Both options filter your water. The difference is where — and that changes everything about what you get for your money.

Under-sink filters: one tap, done well

An under-sink unit sits in the kitchen cabinet and filters the water at a single point — usually a dedicated drinking tap. It's a solid choice if your only concern is drinking water, you rent, or your budget is tight. Upfront cost is lower, and installation is simpler.

The limitation is obvious: it does nothing for your shower, laundry, bathroom taps, dishwasher or hot water system. If chlorine smell in the shower bothers you, or sediment is chewing through appliance valves, an under-sink unit won't touch it.

Whole-home filters: every tap, every appliance

A whole-home system is installed on the mains line where water enters your property. Everything downstream — showers, washing machine, dishwasher, hot water service, every tap — gets filtered water. Our 3-stage system reduces sediment, rust, chlorine, odour and organic compounds across the whole supply.

The benefits people actually notice: better-tasting water everywhere, less chlorine smell in the shower, and less sediment and scale stress on appliances. It costs more upfront and needs a licensed plumber to install — in Victoria, mains-connected work must be done by a licensed plumber anyway.

The honest decision guide

• Just want better drinking water? Under-sink is fine.
• Care about showers, appliances and whole-house taste? Whole-home.
• Renting? Under-sink (with landlord sign-off) — whole-home is a property owner's game.
• Own your home and planning to stay? Whole-home is usually the better long-term value, especially with cartridge resupplies bundled in.
