Well Water & Special Purpose Water Filters

Acid Neutralizing Water Filters
Acidic water can leach unhealthy levels of copper from pipes, cause greenish-blue stains on fixtures, and cause corrosion in appliances and fixtures.
Arsenic Water Filters
Arsenic is highly toxic and finds its way into a water supply from mining, metallurgical, or agricultural activities. The maximum contaminent level for arsenic is 0.010 milligrams/liter.
Ceramic Water Filters
Ceramic water filters remove harmful bacteria such as E. Coli, Fecal coli form, Salmonella, Streptococcus, and cysts (Cryptosporidium, Giardia), as well as particles and sediments.
Fluoride Water Filters
Fluoride (F-) is a common constituent of many minerals. Municipal water treatment plants commonly add fluoride to the water for prevention of tooth decay, and they try to maintain a level of 1.5 - 2.5 mg/l. Concentrations above 5 mg/l are detrimental to tooth structure.
Iron-Manganese Water Filters
Water often contains iron and accompanying compounds that cause a variety of problems, including odorous water, discolored water, corrosive water and a variety of health concerns for drinking water.
Nitrate Water Filters
Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate that occurs in drinking water is the result of contamination of ground water supplies by septic systems, feed lots, and agricultural fertilizers.
Sediment Water Filters
CRYSTAL QUEST® Whole House Sediment Water Filters are designed for the removal of turbidity in the water caused by sand, silt, ferric iron and oxidized manganese or sulfur.
Tannin Water Filters
Self-backwashing systems that automatically remove the tannins within the filter bed and washes them down the drain!
