Sanders Home Services uses Guardian Air by RGF™ technology for our customers’ air purification needs.

The Guardian Air by RGF™ is designed to eliminate sick building syndrome risks by reducing odors, air pollutants, VOCs (chemical odors) smoke, mold, bacteria and viruses. The HVAC-PHI Cells are easily mounted into air conditioning and heating systems air ducts where most sick building problems start. When the HVAC system is in operation the HVAC-PHI Cell creates and Advanced Oxidation Process consisting of Hydroperoxides. All are friendly oxidizers. By friendly oxidizers we mean oxidizers that revert back to oxygen and hydrogen after the oxidation of the pollutant.

The RGF PHI™ Advantage

While UV systems are designed to kill mold on the HVAC coil, The Guardian Air does this, plus it adds advanced oxidants throughout the room to kill microbials at the source.


With a Guardian Air HVAC Cell Advanced Oxidation System, micro-organisms can be reduced by over 99%. Gases, VOCs and odors can also be reduced significantly. Advanced Oxidation Plasma will be carried throughout the ducts and rooms for a continuous purification process and a quick kill of newly introduced odors or microbials.
