Working with LEDARS, their goal is to distribute 200,000 Biosand Filters in Bangladesh alone over the next six years.
Since beginning their Biosand Filter implementation in 2014, OHorizons
has helped communities with unclean water build over 1,530 Biosand Filters, providing approximately 7,650 people with access to clean water right in their homes.
This biological layer(or“biolayer”) takes about a month to develop naturally,
and once it does the Biosand Filter can effectively remove up to 98% of bacteria,
up to 99% of viruses and protozoa, and up to 100% of worms.
