How Is This System Different?
How the Dual Filter Works - 2 Cartridges - 5 Stages

Removes Contaminants Sequentially through Cartridges "A" & "B"

Aquasana AQ4000's exclusive dual cartridge, 5 stage, filtration system uses a combination of the most advanced technologies available. This patented process selectively removes contaminants sequentially, in a certain order, based on their level of prevalence and degree of competitiveness. This allows the system to achieve the full potential of each stage of filtration.

Cartridge "A"

Stage 1: Removes sediment and turbidity first. These are tiny microscopic particles that can clog the pores of a filter media and reduce its ability to remove the contaminants.

Stage 2: Next chlorine is removed, the most concentrated and the most competitive chemical in our water. This allows the following stages to focus on the more difficult task of removing lead and synthetic chemicals. After water has been through these first two stages of filtration it then passes over to the "B" cartridge.

This pre-filter Cartridge "A" reduces particles invisible to the human eye (5 microns).

Cartridge "B"

Stage 3: First lead is removed by a complex ion exchange process where lead ions are replaced with potassium ions. This exchange is the most effective method for removing dissolved lead and also enhances the natural mineral balance of water. Potassium is also one of the minerals that helps give water a natural spring water taste and a neutral pH.

Stage 4: Next is the most challenging and possibly the most important stage, the removal of synthetic chemicals, like herbicides, pesticides and industrial solvents. These are some of the most harmful contaminants found in our water and also the most difficult to remove.

This is where the AQ-4000 dual cartridge system really differs from other brands.

Because the competitive influences of chlorine, lead and sediment have already been removed, this Stage 4 can focus on the essential task of eliminating organic chemical compounds, and does so to a higher degree than any other product.

Stage 5: In the final stage, a 0.5 micron compressed carbon filter removes water borne parasites or cysts like cryptosporidium and giardia. These chlorine resistant organisms are commonly found in drinking water supplies, causing flu like symptoms for most, but can be fatal to small children and the elderly. This is an essential stage for complete contaminant protection.

In Cartridge "B" the coconut shell carbon combines with potassium-charged zeolite to extract lead and replace it with natural potassium ions.
