What Does This Mean For You?

Detecting Bacteria & Pathogens in your water supply does not necessarily mean immediate danger, but long-term exposure -- even at low levels -- carries measurable health risk. UV purification systems and sub-micron filters (0.2 micron) eliminate bacteria and pathogens.
