Bio-Sand Filters

Bio-Sand filters use the bounty of nature to purify water. All-natural materials, such as sand and gravel trap the majority of contaminants, without the need for electricity, expensive parts or regular maintenance.

The filters will be forged by local cooperatives and craftspeople, using techniques that have been honed by field testing worldwide.
Lab Studies Have Shown that The Filters Eliminate:

  • 100% of viruses
  • 99% of parasites, protozoa, amoebas, worms
  • 98% of all bacteria
  • 95% of zinc, copper, iron, lead
  • 93% of arsenic
  • Illnesses such as Typhoid, Cholera, Hepatitis A, E-coli, Rotavirus and Dysentery
