Assessing the Effectiveness of a Water Filter Technology as an Arsenic Mitigation Strategy in West Bengal

The Pureit As+ water filter has been developed to effectively remove arsenic (both arsenite and arsenate) from over 300 µg/L to less than 10 µg/L in addition to removing microbial contamination (Institution of Public Health Engineers, 2011). It has an end-of-life indicator and consumables that do not re-contaminate the environment when disposed (Institution of Public Health Engineers, 2011). The technology requires no electricity, but only the replacement of the battery after 1000 L of water filtered (approximately 100 days based on a family of five drinking 2 L/day).
