Arsenic is highly toxic and has been classified by the US EPA as a carcinogen, which was derived from toxicity considerations rather than carcinogenicity. If you have Arsenic in your water, your health is in danger and you definately need to remove it!! Arsenic (As) is not easily dissolved in water. Therefore, if it is found in a water supply, it usually comes from mining or metallurgical operations or from runoff from agricultural areas where materials containing arsenic were used as industrial poisons. Arsenic in water has no color, taste or odor.  All of our Arsenic removal filters contain an Arsenic specific Resin, while others combine additional filter cartridges to remove other contaminants such as organic compounds and bacteria.
