Every Polaris UVA System Includes
304 stainless steel reactor chamber, high-quality quartz sleeve, microprocessor-controlled ballast, and an LED indicator with visual and audible lamp-status alarm. UV disinfection works instantly without adding chemicals or changing the taste, odor, pH, or conductivity of your water.
Ideal Applications
Whole-house point-of-entry well water, larger residential systems, and light commercial applications needing high-output single-lamp disinfection with an audible failure alarm and day counter.
💧 Pro Tip: Install a 5 micron sediment pre-filter upstream to protect the quartz sleeve, replace the UV lamp every 12 months, and clean the sleeve every 3–6 months if hardness exceeds 7 grains or iron exceeds 0.3 ppm.
