A UV water disinfection system can destroy 99.99% of harmful microorganisms (bacteria, viruses, cysts) to ensure all water in a home is free of viruses and bacteria 24/7.
The Centers for Disease Control and Prevention (CDC) site states: “Ultraviolet Light (UV Light) can be used as a pathogen reduction method against some microorganisms. The technology requires effective prefiltering due to its dependence on low water turbidity (cloudiness), the correct power delivery, and correct contact times to achieve maximum pathogen reduction. Manufacturer’s instructions must be followed.”
Many people choose to install a UV system as an added layer of protection, even if a home receives water from the city, because the public water system is often vulnerable to impurities leaching in UV disinfection is considered to be a safe, economical, and a chemical-free way of disinfecting your water.
The UV system’s effectiveness is dependent on correct system sizing and low sediment and turbidity/cloudiness in the water. A prefilter before a UV system, can help remove sediment and cloudiness so that UV light can effectively inactivate viruses.
