Iron is one of the Earth’s most plentiful resources, making up at least 5% of its crust. In well water, iron is usually found as ferrous iron, which is in a dissolved state, potentially causing water to appear clear when first drawn from the tap.
Oxidizing filters combat problematic iron contamination
HaloPure removes 99.9% of viruses and bacteria while also preventing bacterial recontamination. Its uses are versatile and it can be applied to a variety of gravity and pressure POU devices. The media has been proven to enhance systems to help them exceed drinking water standards. It can be used with pitcher applications, inline, or with standard 10-in. cartridges for countertop and undersink systems.

The town of Newport Center, Vt., is a small community of approximately 1,500 residents located just south of the U.S.-Canada border. A combination of drought and increased water use required the drilling of a new well for the community to supplement the two wells already in service. Water quality testing of the new well found arsenic levels at 20 ppb, well above the drinking water standard set by the U.S. Environmental Protection Agency (EPA) and the state of Vermont of 10 ppb.
