What's the Best Water Filter System for Australian Homes?

There’s no single “best” water filter — the right system depends on what’s in your water, how much filtered water you need, and your budget. Here’s a practical comparison of the main types available in Australia to help you choose.

For detailed guides on each system type, see our pillar pages: Whole House Filters, Reverse Osmosis, Benchtop Filters, Under Sink Filters, and Water Distillers.

Step 1: Know What’s in Your Water

Australian town water is treated with chlorine or chloramines and may contain fluoride, heavy metals, sediment, and disinfection by-products depending on your location and pipe age. Bore and tank water may also contain bacteria, iron, and high sediment loads.

Your local water utility publishes an annual water quality report — check their website to understand what’s in your supply before choosing a filter.

Water Filter Types Compared

Whole House Water Filters

Installed on the main supply line — filters every tap, shower, and appliance in the home. Best for removing chlorine, sediment, and heavy metals from all water points. Doesn’t remove fluoride. Ideal for families who want comprehensive protection without point-of-use filters at every tap. Browse our whole house filter range.

Reverse Osmosis Systems

Installed under the kitchen sink — produces very high purity water on demand from a dedicated tap. Removes up to 99% of contaminants including fluoride, heavy metals, chlorine, and bacteria. Many models include a remineralisation stage. Best for drinking and cooking water. Browse our RO range.

Benchtop (Countertop) Water Filters

Gravity-fed or mains-connected units that sit on the bench. No plumbing required for gravity models — ideal for renters or those who want a simple setup. Our 8-stage KDF benchtop filters use multi-stage filtration including KDF, activated carbon, ceramic, and mineral stones. Best for drinking water without installation.

Under Sink Water Filters

Installed under the kitchen sink with a dedicated filtered water tap. Connects to mains water for on-demand filtered water. More discreet than benchtop units. Browse our under sink filter range.

Water Distillers

Produces the highest purity water of any home method — removes virtually everything including fluoride, bacteria, heavy metals, and dissolved minerals. Slower (4–5 hours per 4L batch) but no plumbing required. Best for maximum purity, CPAP use, or renters. Browse our water distiller range.

UV Sterilisers

Uses ultraviolet light to kill bacteria, viruses, and parasites without chemicals. Doesn’t remove dissolved contaminants — best used as a final stage after sediment and carbon filtration. Essential for bore water and tank water.

Water Softeners

Uses ion exchange to remove calcium and magnesium (hardness minerals), reducing scale buildup in pipes and appliances. Doesn’t remove chemical contaminants. Best for homes with hard water issues.
