How the 2-Stage Aquasana Water Filter Works:

PhotobucketA” Cartridge (left cartridge in diagram):
Flters out heavy sediment and tiny microscopic particles that can cause cloudiness, unpleasant taste, and odor in your water. It also filters out chlorine, the most concentrated and competitive chemical in our water.

“B” Cartridge (right cartridge in diagram):
Focuses on the more difficult contaminants like lead and VOC’s. Lead is filtered out by a complex ion exchange process where lead ions are replaced with potassium ions. Potassium is one of the minerals that gives water a natural spring water taste and a neutral PH.

Next for the Aquasana Water Filter “B” cartridge is the adsorption of VOC’s, like herbicides, pesticides and industrial solvents. The “B”cartridge also has a 0.5 micron mechanical filter for chlorine resistant organisms and common water-borne parasites that can cause flu like symptoms for most, but can also be fatal to small children and the elderly.

The replacement cartridges (A&B) for the AQ-4000 countertop water filter cost only $47.99 (with “Water For Life”) and last 6 months or 500 gallons.

Important: Do not use Aquasana Water Filter 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.

Aquasana is the #1 rated home water filtration system in America.
