Aamara Biswas started this project in 2010. In the beginning women bought the filters under the Nano Finance scheme. There has been a significant reduction in waterborne diseases by using the water filters. Though the women understand the benefit of these filters, still they prefer to spend money towards building a livelihood rather than buying the filters. Getting them to return this loan was difficult and took more than a year. Most of the women returned their loans after multiple visits to their homes. Aamara Biswas has decided not to give the filters under the Nano Finance scheme; instead, the women have to just buy them. Aamara Biswas does not invest any amount to expand the project. The return money is re circulated for buying the parts and new filters.
