Patented filtration technology

Aquasana's Countertop Water Filter relies on patented 'Selective Filtration' to deliver the purest, healthiest water to your home. Inside the Countertop unit sits a twin cartridge which runs water through a multi-stage filtration system including mechanical filtration, adsorption, and ion exchange.

Selective Filtration filters out over 100 tap water contaminants, synthetic chemicals and bacteria whilst preserving natural healthy minerals.

Two cartridges for ultra-pure water

Cartridge A filters out turbidity and microscopic sediments out of the water, removing unpleasant taste and odor as well as cloudiness. Cartridge A also removes 99% of chlorine, one of the chemicals present in the highest concentration in unfiltered tap water.

Cartridge B adsorbs the more difficult chemicals still present in water such as industrial solvents, pesticides and herbicides. Equipped with a 0.5 micron mechanical filter, Cartridge B also removes microscopic chlorine-resistant bacteria such as giardia and cryptosporidium (parasites that can be fatal in small children and the elderly). In the final filtration stages, an ion-exchange process filters out 99% of Lead and increases the concentration of Potassium ions, giving the water pH stability (between 7.25 and 8.5) as well as a pleasant 'spring water' taste.

Economical and healthy

Forget about mineral water in plastic bottles! It's not just expensive, it's also a dangerous alternative to home-filtered water as most plastic bottles contain BPA, a chemical that can leach and contaminate the water.

Made of sturdy recycled plastic and stainless steel, the Aquasana range stands the test of time and will deliver great tasting pure filtered water at only 4 cents per Litre! Each filter cartridge replaces an equivalent of over 2000 plastic water bottles.
