Antimicrobial efficacy of the LARQ Bottle against E. coli

This purpose of this study was to determine how effective a LARQ Bottle was at killing E. coli at 1-min, 2-min, and 3-min treatments. The LARQ Bottle yielded a log reduction of 3.72 and killed 99.9775% of E.coli at 1 minute. The LARQ Bottle yielded a log reduction of 5.66 and killed 99.9998% of E. coli at 2 minutes. The LARQ Bottle yielded a log reduction of 6.08 and killed 99.9999% of E. coli at 3 minutes.
