Power of the sun

280 nanometer UV light

Is ideal to eradicate germs, triggering a photochemical reaction that destroys their DNA. UV-C light is widely used today in hospitals to sterilize patient room surfaces.
When UV light is absorbed, it breaks the DNA's chemical bonds and kills the bacteria or virus

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.
