UV Water Treatment Systems for Homes & Wells
UV treatment is a specific treatment stage, not a catch-all filter. It belongs in a plan when testing or qualified guidance identifies a microbial concern and the water is properly prefiltered for the system.
This page is for you if a UV treatment stage is appropriate
Look here when:
- a private-well test or qualified water professional identifies a microbial treatment need;
- you want a treatment stage after sediment and water-quality conditions have been evaluated; or
- you are prepared to match the system to household flow, plumbing, power, and lamp-maintenance requirements.
UV does not remove sediment, minerals, PFAS, or dissolved metals. Compare UV systems by documented flow capacity and required prefiltration, then confirm that your plumbing and water conditions fit the product instructions. Continue to use a current test and local guidance for well-water decisions.

- Compare UV systems by the required installation location and the flow rate specified on the product page.
