The Venture Capital fund Danone Communities evaluating Aqua Clara-Kenya requested that our two-bucket hollow membrane-based filters (2B HHFs) be tested by NSF. Because the AC-K filters employ all elements of our design as well as parts, and only provide locally-sourced buckets, we agreed to send two of our 2B HHFs to NSF in Ann Arbor, Michigan. Doing so would obviate the need to ship the same filters from Nairobi.

The results of the NSF testing showed the results we already knew; 99.9999% reduction of all harmful biological contaminants from source water.
