Installation costs vary significantly by type. Here are real 2026 ranges — unit plus professional installation included.
Added to all Australian municipal water supplies as disinfectant. Safe at regulated levels but affects taste and smell. Carbon filters remove both effectively — the most common reason Australians buy filters.
Detected in water supplies near airports, military bases, and industrial sites across Australia. Linked to health concerns. Requires activated carbon or reverse osmosis to remove — standard filters are insufficient.
Lead, copper, and arsenic can enter water through ageing pipes and fittings. Most common in older homes (pre-1970s). Reverse osmosis and certain carbon block filters remove heavy metals effectively.
Particularly relevant for tank water and bore water. UV filters kill bacteria and viruses. Sediment filters (typically 1–5 micron) remove particles. Required in rural and off-grid water systems.

All plumbing connections in Australia require a licensed plumber. We verify licences, insurance, and WaterMark compliance before matching.
Australian law requires WaterMark certified products for all plumbed water systems. We explain what this means and why it matters for your protection.
Australian tap water meets strict safety standards and is safe to drink in all major cities. However, "safe" and "optimal" are different things. Chlorine and chloramines (used as disinfectants) are safe at regulated levels but cause the characteristic smell and taste many people find unpleasant. In areas with PFAS contamination, heavy metals from ageing pipes, or high sediment from tank water, filtration addresses genuine quality concerns beyond taste. Most Australians who install filters do so for taste improvement first, and additional health reasons second.
For benchtop and some tap-attachment filters: no — these are DIY-friendly. For under-sink filters, reverse osmosis systems, and whole house systems: yes, a licensed plumber is required in Australia. Any connection to the mains water supply is "plumbing work" under Australian law and must be performed by a licensed plumber. The plumber will also issue a certificate of compliance where required. Using an unlicensed person voids product warranties and home insurance.
WaterMark is Australia's mandatory certification scheme for plumbing products that contact drinking water. It verifies that a product has been tested to Australian standards and is safe for use in our water supply systems. Any water filter that connects to your plumbing must be WaterMark certified. This is a legal requirement, not optional. When buying a filter, confirm WaterMark certification before purchasing — some cheap imported units don't have it, making them illegal to connect to Australian mains water.
