Plug & Play UV-C LED
Your RO system removes sediment, chlorine, and heavy metals. But bacteria, viruses, and cysts can still pass through. The Pulsar UV uses ultraviolet light to destroy their DNA on contact — giving you hospital-grade disinfection at the tap, with zero chemicals added to your water.
Especially if you're on well water, have immune-compromised family members, or want an extra layer of safety for kids and aging parents.
Unlike chlorine or iodine, UV leaves nothing behind. Just pure, clean, and refreshing disinfected water.
The Pulsar runs 24 months before you even think about replacing the LED. No annual lamp changes. No quartz sleeves to clean or crack.
The Pulsar replaces old-school mercury UV lamps with a modern, cool-running LED that's safer, smarter, and more efficient.
9,000-hour rated LED. One replacement every 2 years — not every 9–12 months like traditional UV lamps.
Less power than a night light. No standby heat. No wasted energy.
Traditional UV lamps heat the water sitting in the line — giving you a burst of warm water at the tap (and potential leak risk when you're away). The Pulsar stays cool, so every pour is refreshing and safe.
Most UV systems trap minerals and sediment on the UV lens. The Pulsar pulls particles away from the light source, so your UV stays cleaner longer.
No hazardous materials. No special disposal. Safer for your family and the planet.
Most UV systems use a fragile quartz tube that minerals coat over time, blocking UV rays and forcing early replacement. The Pulsar uses a no-fouling window instead — nothing to scale, nothing to crack, nothing to replace annually.
3.5″ × 2″ × 3.65″ with ¼″ quick-connects. Installs beside any RO system, under any sink, or inside any RV.

For optimal performance, the incoming water for this UV system must be clear of sediment, scale, and high mineral content to ensure the ultraviolet light effectively reaches all microorganisms. If your home is supplied by a private well, you must have your water professionally tested before installation to confirm it meets the required quality standards. In cases where iron, hardness, or turbidity exceed these limits, proper pre-filtration is required to prevent voiding the warranty.
Overall rating: 5.0 / 5 from 2 reviews.

"We were concerned there might be a flow restriction with the LED UV filter, (3/8" to 1/4"), but if there is a reduction it is not apparent."
— Scott H. (5/5)
"Nice to fit under the sink to take care of the bacteria"
