The Sawyer Mini Filter was tested for its ability to remove three microorganisms –Raoultella terrigena, Bacillus subtilis, and Micrococcus luteus – using USEPA approved procedures. The organisms were added to test water to reach a 107 – 108 initial concentration. The test water followed the criteria set forth by the USEPA 1987, following the conditions for “test water #3”. All of the three tested filters met the target reduction of 6 log units, or 99.9999% for all runs. The Sawyer Mini filter meets theUSEPA standard for bacteria.
