Why Tappwater

Lab-tested, Sydney-run, and built around one idea: better water shouldn't be complicated.

Lab-tested, published

Independent labs test every filter across 70+ contaminants — and we publish the results in full, not just the highlights.

Run from Sydney

Local support from our Sydney team, and weekday orders before 12pm leave the warehouse the same day.

60 days to love it

Try any filter for 60 days. If your water doesn't taste — or feel — better, send it back for a full refund.

Subscribers get lifetime warranty

On subscription, your hardware is covered for life — if anything cracks or wears out, we replace it free.
