Stage 1: Sediment Water Filter
In the first stage, a heavy duty pre filter clears out impurities and sediments from the water. This prolongs the life of the stage 2 and 3 filters. Sediment filters operate efficiently for up to a year.
Stage 2: Chlorine Water Filter
Patent ZL201520326026.5
Patented carbon filter intercepts and removes an extremely high rate of 99.9% of bacteria and chlorides. Odours are eliminated and water taste improves significantly.
Stage 3: Patented RO Water Filter
Patent ZL 200910201739.8
Traditional RO filters have water entering at one end and leaving at the other. These high pressure RO systems usually last no more than a year.
The Max 4 high precision filters can last up to 4 years. They are designed to allow water to stream in from both ends of the filter and be purified through the length of the membrane. This design not only preserves the integrity of the filter for longer, it also improves the entire filtration process.
Highest Water Filter Retention rate
To obtain the cleanest water, all RO water purifiers can retain only a percentage of the water. The more advanced the RO filter, the higher the retention rate.
While other RO water purifiers have a water retention rate of 25%, the AOS RO filter holds the patent for the highest water retention rate of 75%.
Water Filter Replacement Indicator
Light indicator at both hot water faucet and water purifier changes colour to reflect life of the filter, giving you ample time to arrange for filter replacements.
White – Normal
Orange – 5% life
Red – 0% life
Automated Self Cleaning RO Filter
Max 4 auto-cleanser performs a flush through the entire system. It is activated:
- upon powering up or after a reset
- for every 30 min of continuous usage
- for every 72 hours of inactivity

Tips: Water Filter Change
Filter Change
- After changing filter 1, 2 or 3, let water run from the filter tap for 15 min.
Caution
- Do not let filter tap run over 20 min or this will cause ‘leak protection’ to be activated and system will shut down.
