Users can obtain the filters from local partner organizations. ACI requires that interested parties participate in a training program to ensure proper construction, use and monitoring of the units built in the field. Their approach centers on training and supporting individuals and/or organizations to establish and manage micro-enterprises based around purifier construction, sales and service with a focus on sustainability. The filters are distributed by partner organizations who provide filters by donation or locally established micro-enterprises.
