The benefits of AquaTru’s Under Sink water filter system

Discover how this house water filter system maximises space and performance in our feature on the smart space solution for purified water.

The purification process: 4-stage reverse osmosis

The AquaTru under sink water filter system utilises a 4-stage reverse osmosis process to deliver water that is both pure and great-tasting. It begins with a sediment filter, followed by a pre-carbon filter, a reverse osmosis membrane, and a final post-carbon filter. This advanced process, further explained in our guide to reverse osmosis for pure, refreshing water, is identical to the system used in the AquaTru Classic and removes contaminants such as chlorine, arsenic, lead, fluoride, and many others.
