UV Purification
Chemical-Free Protection Against Bacteria & Viruses
Ultraviolet purification destroys 99.9% of bacteria, viruses, and other microorganisms in your water using UV light — no chemicals, no byproducts, no change to taste or odor. Essential for well water users and anyone wanting an extra layer of protection.

How UV Purification Works
Water passes through a UV chamber where it's exposed to intense ultraviolet light at 254 nanometers — the most effective wavelength for destroying microbial DNA. The UV light penetrates cell walls and disrupts the DNA of bacteria and viruses, preventing them from reproducing. The microorganisms are rendered harmless without being removed from the water.
Who Needs UV Purification?
UV purification is strongly recommended for homes on private well water, homes with older plumbing, or any home where microbial contamination is a concern. It's also an excellent add-on to any whole-home filtration system for a complete treatment package.
UV vs. Chlorine
Chlorine kills bacteria through chemical reaction and lingers in water as a residual disinfectant. UV destroys pathogens instantly with no chemical residue, no byproducts, and no effect on water taste or odor. Many well water homeowners prefer UV specifically because they want chemical-free water.
Maintenance
UV systems require annual UV bulb replacement (even if the bulb still glows — UV output degrades before the visible light does). The quartz sleeve surrounding the bulb should be cleaned annually. It's one of the simplest systems to maintain.
Frequently Asked Questions
Is UV purification effective against all pathogens?
UV is highly effective against bacteria (E. coli, coliform, salmonella), viruses, and protozoa like Giardia and Cryptosporidium — which are resistant to chlorine. However, UV does not remove dissolved chemicals or heavy metals. For complete protection, UV is often paired with a carbon filter.
Does water need to be clear for UV to work?
Yes — UV works best in clear water. Turbidity (cloudiness) or color can shield microorganisms from UV exposure. We always recommend a sediment and carbon pre-filter before a UV system. We'll assess your water and design the right system.
How much power does a UV system use?
UV systems are very energy-efficient. A typical residential unit uses about 25-55 watts — similar to a standard light bulb — running continuously. Annual electricity costs are typically under $25.
Can I use UV on municipal water?
Yes, though municipal water is already chlorinated. Many homeowners add UV as a secondary layer of protection, especially if they also have a whole-home filter that removes the chlorine, which eliminates the residual disinfectant protection. UV restores that protection naturally.
