Arsenic Removal Filter by NuWaterUSA.
This filter uses the technology of ion exchange to remove arsenic from water. It is effective over the entire pH range of potable water and is the ideal for home filtering of tap water containing arsenic of less than 10ppb (parts per billion). Arsenic has a positive charge and the media in the filter has a negative charge attracting and holding the arsenic to itself. While water with unsafe levels of arsenic can be used for washing clothes and bathing, drinking it will cause long term arsenic poisoning in humans and animals. Suspended solids and iron will decrease the efficiency of this filter, so be sure to obtain a water analysis if running well water to determine the best filtration system for your drinking water.
