Seldon’s Filter Used by Troops

Windsor — A water-purifying system developed by Seldon Technologies Inc. has passed the U.S. military’s most rigorous protocols and is now being used by troops in the field.

The Windsor-based company’s WaterBox filtering system uses nanotechnology, not chemicals, to make contaminated water safe for drinking. It is specifically designed for military, disaster recovery and humanitarian assistance agencies. The unit fits in suitcase and runs off AC or DC power, so it can be connected to vehicle battery. It takes about two minutes to set up and produces purified water from highly contaminated sources, company spokeswoman Heidi Luquer said last week. In fact, on the Seldon website (, a video shows a company official demonstrating the WaterBox by drinking water purified from the initial intake tank at the Hanover water treatment plant.

The portable unit costs $7,900 and can produce 30 gallons of potable water an hour, or 720 gallons a day, enough to supply a platoon of soldiers, Luquer said.

“It’s being used now (by) the Marines and others. The Vermont National Guard took it to Afghanistan,” Luquer said. “It’s pretty amazing.”

Seldon has received Environmental Protection Agency approval to sell the WaterBox outside of the United States and to the military inside the country. The company is now seeking the OK to sell the units to the public.

The company also is working on lower-cost unit for public use, Luquer said.
