The system is designed for common kitchen and bathroom taps and covers approximately 90% of standard Australian faucets.

It is not suitable for pull-out spray heads, concealed (internal) aerators, or very unusual shapes such as square designs.
Before purchasing, please ensure that your aerator can be unscrewed.

Reduces chlorine, odors and unpleasant taste for noticeably better drinking water. The system is designed to improve water quality and taste. It does not remove limescale, as it is not a reverse osmosis system.

Approximately 3–6 months of clean, great-tasting water.
Depending on water quality and daily usage, one cartridge filters around 2,000 liters.

In areas with heavily contaminated water, replacement may be required sooner.

Please note: The filter is designed to improve the taste and quality of potable tap water.
It does not convert non-drinkable water into safe drinking water.

Covers approximately 90% of standard Australian faucets.

The system fits common M22 (female thread) and M24 (male thread) faucets.
To ensure maximum compatibility, the following adapters are included:

1× M22 to M24 adapter (male to male)
→ For faucets with M24 female thread

1× 20 mm female to M22 male adapter
→ For faucets with 20 mm male thread

1× Universal adapter
→ Designed for special sizes or uncommon faucet shapes

If your faucet falls within the remaining 10%, compatible adapters are widely available at most hardware stores or online.

Quick and tool-free installation in just a few minutes.

In most cases, simply unscrew the existing aerator, attach the filter system, and you're done.
If needed, screw on the appropriate adapter first and then attach the filter.

Please note that some faucets have an externally threaded aerator, while others use an internal (concealed) aerator. This can sometimes be difficult to recognize.
Make sure your aerator is removable before purchasing.

In rare cases, if the aerator has been tightened for a long time or is affected by limescale buildup, a wrench may be required to loosen it.
After removal, installation is straightforward.
