UV is the standard answer for wells with a positive bacteria test and for rainwater harvesting, and the Pulsar is a competent implementation of it. The prefilter matters more than buyers expect: UV only works on water clear enough for the light to penetrate, so the 1-micron Magna cartridge is not an upsell but a functional requirement on most well water, and the double O-ring seal exists to stop unfiltered bypass reaching the chamber. Sizing is by flow, and the three configurations are priced meaningfully apart, so measure peak household demand rather than guessing. Running costs are a lamp annually and occasional sleeve cleaning. Note that the price range across configurations is wide, and the entry figure reflects the smallest chamber without the filter package.
- Chemical-free disinfection with no taste or odour change
- Three flow ratings for household sizing
- 1-micron Posi-Seal prefilter option addresses the turbidity that defeats UV
- Effective against bacteria, viruses and protozoa
- Integrates with the whole-house filters in the range
- Requires clear water to work, so a prefilter is effectively mandatory on well supplies
- Annual lamp replacement and periodic sleeve cleaning
- No residual disinfection downstream of the chamber
- Wide price spread across configurations, so the entry price is not the typical price
- No system certification stated
- Ten-year chamber cover falls to three years on the electronics and one year on lamps, sensors and quartz sleeves
Whole-house ultraviolet disinfection in 10, 15 and 20 GPM configurations, supplied with an optional 1-micron American-made Magna prefilter using Posi-Seal double O-ring technology. UV inactivates bacteria, viruses and protozoa physically, without chemicals and without altering taste.
