You get the very best water, the best value and the most convenience, at a fraction of the cost of bottled water!

Aquasana's exclusive dual filter system uses a combination of carbon filtration, ion exchange and sub micron filtration to produce truly healthy, great-tasting water conveniently from your kitchen tap. Filters out chlorine, lead, prescription drugs, pharmaceuticals, VOCs, MTBE and cysts (chlorine-resistant parasites) and leaves in the natural trace minerals!

The AQ-4000 is certified by the California Department of Health Services, the most rigorous certification entity in the world, to remove greater than 99% of alachlor, benzene, lindane, TCE, THMs, cryptosporidium, giardia, and VOCs, more than 97% of atrazine, and more than 93% of MTBE. Removal of benzene, atrazine, MTBE, VOC, cyst and THM is unique to the Aquasana AQ-4000. It performs better, has a more attractive design and, at $.09/gallon, the AQ-4000 is much more economical to use than a pour-through pitcher filter!

Naturally healthy, great-tasting water at the touch of a button for under 10¢/gal. No other product, at any price, has ever produced better results than Aquasana! Aquasana's contaminant reduction capabilities are third-party tested and certified by the California Department of Public Health Services.

IMPORTANT: Do not use where water is microbiologically unsafe or with water of unknown microbiological quality, except that systems claiming cyst reduction may be used on water containing cysts.
