Guardian Air QR+ Indoor Air Purification System

The Guardian Air QR+ in-duct Indoor Air Purification System utilizes RGF’s proprietary PHI-CELL® technology.

Installed into the supply plenum of your existing air conditioning or heating system air ducts, the Guardian Air QR+ in-duct air purifier produces low level, airborne hydrogen peroxide molecules that are distributed by the air handler, through the duct system and into the conditioned space. Unlike passive air technologies, which need pollutants to pass through the unit for purification or filtration, the Guardian Air QR+ in-duct air purifier sweeps through the air conditioned space actively purifying pollutants at the source.

Why Use RGF’s PHI-CELL® Technology?
Photohydroionization® (PHI) is an active air treatment technology. Active air treatment is the process of reducing air and surface contaminants by recreating safe, natural levels of hydrogen peroxide (H2O2) in occupied areas.
RGF’s patented PHI-CELL® technology combines a photocatalytic process and a multiwavelength UV source to create active air purification. The combination of UV-C light and a hydrated quad-metallic catalyst drives a reaction that produces low level, airborne H2O2. RGF’s PHI-CELL® air treatment systems are operating safely in over four million installations globally
It operates silently and continuously, so once it’s installed, the only thing you’ll notice is how fresh your home smells – and how comforting it is to help protect everyone around you.
  • Installation is quick and easy
  • One of the least expensive components of an air conditioning system, but one that can have one of the biggest impacts on your air quality.
  • Active technology reduces viruses, bacteria, mold spores and odors right at the source to give you the freshest air possible.
  • Can be easily integrated into your existing air conditioning duct system.
  • Reduces odors from mold, pets and smells from old homes.
  • Silent, continuous operation so you only notice how fresh your home is.
