The UVF11A Sterilizer Water Filter is a complete add-on kit that can be added to most RO systems as a final stage. The UV sterilization stage kills the small percentage of viruses, bacteria, and other microorganisms that could potentially remain in the water after the RO process. Though most municipal water systems do an adequate job of removing organic microorganisms, the UV stage is a must if the source water is coming from a well, lake or stream where microorganisms breed, or other residential uses where bacteria is a concern. Combining a Reverse Osmosis filtration system with UV sterilization provides the most complete method of water purification available.

The UVF11A features an 11 watt sterilization lamp shielded in a safe, protective stainless steel housing versus the 6 watt lamp commonly found in other products. For greater efficiency, a flow sensor switch turns the UV unit on and off automatically with water flow, saving power and lengthening the life of the UV lamp.

What's included:

  • Stainless steel housing with Quartz sleeve
  • 11W Germicidal UV lamp
  • 110V Electronic ballast with Smart Flow Control Switch and Rubber O-ring
  • 2 quick-fittings
  • 2 brackets to hang the filter on the wall
  • User Manual
