The Aquasana AQ-4000 Water Filter is a Drinking Water Enhancement System providing ultra high quality filtered water for only $1.80 per week!
The Aquasana AQ-4000 Countertop Filter is a twin stage filtration system that can be easily attached to your tap.
The "A" cartridge filters out sediment and turbidity first; tiny microscopic particles that can cause cloudiness and unpleasant taste and odor in water.
The "A" cartridge also filters out chlorine, the most concentrated and the most competitive chemical in our water.
This allows the following stages in cartridge "B" to focus on the more difficult contaminants like lead and synthetic chemicals.
The "B" cartridge is where the final stages of filtration take place. Lead is filtered out by a complex ion exchange process where lead ions are replaced with potassium ions.
The process is highly effective and also enhances the natural mineral balance of water. Potassium is one of the minerals that gives water a natural spring water taste and a neutral pH.
Next is the most challenging and possibly the most important stage, the adsorption of synthetic chemicals, like herbicides, pesticides and industrial solvents.
The "B" cartridge is also a 0.5 micron mechanical filter effective for chlorine resistant microscopic organisms like cryptosporidium and giardia, two common water borne parasites that can cause flu like symptoms for most, but can also be fatal to small children and the elderly.
