Arsenic Water Filters and Purifiers
Arsenic can be found in wells and ground water in two forms: Arsenic V (inorganic), pentavalent, arsenate and Arsenic III (organic), Trivalent, arsenite. KDG/GAC cartridges will only remove inorganic arsenic, Arsenic V, and reverse osmosis membranes will remove both forms. KDF removes heavy metals, pesticides and fertilizers. However, arsenic removal is not as simple as some of the other contaminants. To remove Arsenic III, you need to change its structure to Arsenic V, and chlorination is used in this method. Another method, using a specially treated iron oxide media (see cartridge below), will remove both types of arsenic. Here are links to articles and methods for removing arsenic:

Our CTD-AR filter was recently tested and compared to two other filters in a study from the College of Engineering, The Ohio State University, entitled "Assessment of the Drinking Water System and Water Quality at
Montaña de Luz and Nueva Esparanza, Honduras
Spring Break 2008" with excellent results!
EPA's acceptable level for arsenic in water is 10 ppb (or .010 mg/L)
Filter AR. This is the only 10" standard housing cartridge (for removing both Arsenic III and Arsenic V using a proprietary iron oxide media, capacity: up to 50 ppb & 1,000 gallons. Designed to treat .050 mg/L (ppm) of total arsenic to less than the EPA standard .010 mg/L (based on a pH of 8.5). For best performance, water flow rate should be 0.5 gpm or less, pH from 6.5 to 8.5, less than 0.5 ppm iron and less than 0.05 ppm manganese. Also removes lead, chromium, cadmium, molybdenum, zinc and antimony. The iron oxide media is NSF-61 certified. 10" cartridge (9.75 x 2.75), fits most standard housings.
