Whole-Home UV

Ultraviolet disinfection, usually for wells.

An ultraviolet lamp the water passes through on its way into the house. It is the standard answer to a well that has tested positive for bacteria. It does nothing for hardness, iron or taste — it is for one job only.

Best for: Private wells, especially after a positive bacteria test
