UV Water Purification Systems in San Diego

Ultraviolet purification destroys bacteria, viruses, and other microorganisms in your water without adding chemicals. It does not remove dissolved contaminants or minerals — but for homeowners on well water or concerned about pathogen protection, it is the most reliable non-chemical solution available.

Salt-Based vs. Salt-Free Water Softeners

We believe in being straight with homeowners. UV is powerful, but it isn’t a cure-all. Here’s the honest breakdown.

What UV does

Destroys bacteria, viruses, and protozoa (including E. coli, Giardia, Cryptosporidium)
Works continuously, 24/7, with no chemicals or byproducts
Provides reliable, on-demand disinfection at the point of entry
Doesn't change the taste, smell, or pH of your water

What UV doesn't do

When UV makes sense

UV is most commonly installed in San Diego homes on private wells, in older homes with aging pipe infrastructure, or as part of a comprehensive multi-stage system. For municipal water users concerned about pathogen protection, UV adds a layer of insurance that chemical disinfection alone cannot fully provide.

Private well water

Wells aren’t municipally treated. UV gives you reliable, continuous pathogen protection.

Older homes & aging pipes

Deteriorating infrastructure can introduce microbial contamination between the main and your tap.

Disaster & outage recovery

Post-earthquake or boil-water advisories — UV adds a dependable layer of safety.

• Recommended approach •

UV + whole-house carbon filtration

Most Pure Water installations pair UV with a whole-house carbon filter. The carbon handles chlorine, chloramine, taste, odor, and many chemical contaminants. The UV chamber takes care of any pathogens that slip through. Together, they cover the widest possible range of water quality concerns — without resorting to chemical disinfection inside your home.

STEP ONE

Carbon pre-filter

Removes chlorine, chloramine, taste, and odor

STEP TWO

Sediment stage

Clears particulates so UV light penetrates fully

STEP THREE

UV chamber

Inactivates bacteria, viruses, and protozoa
