The Heat Pump Store is featuring two superior air filtration systems, at this time:
The Mini Split PHI Cell and the Quad-MS Ion Generator. Both are from RGF®.


The Quad-MS™ removes dust, dander, pollen, mold, bacteria, and
other airborne particles for cleaner air!

The Quad-MS™ Ion Generator for mini split units was developed to help filters remove more airborne particles from the air.

This system has four unique emitters for superior bi-polar ionization. The QUAD-MS™ reduces all types of particulate, such as smoke, bacteria, viruses, and mold spores. Airborne particles receive an electronic charge which causes them to stick together, making them easier to trap and be collected by your system’s filter. The unit is designed to be easily mounted to the top of mini split units. The QUAD-MS™ is a great air quality solution for the budget minded consumer. For best results, run fan continuously.

The Quad-MS Ion Generator attaches to mini split HVAC units with adhesive tabs. It is powered by the indoor unit. No modifications to the system required.


The Mini Split PHI Cell by RGF® is designed to reduce air pollutants such as:
VOCs (chemical off-gasses), odors, smoke, mold, bacteria, and viruses.

The Mini Split HVAC – PHI Systems are easily mounted onto indoor units using adhesive strips. When the HVAC system is in operation the Mini Split HVAC-PHI Cell creates an Advanced Oxidation Process consisting of: Hydro-peroxides, super oxide ions, and hydroxide ions. All are friendly oxidizers that revert back to oxygen and hydrogen after destroying the pollutant.

Why Use Photohydroionization Technology?

Germicidal UV light rays have been used for decades by the medical industry as a method for destroying micro-organisms (germs, viruses, bacteria). UV light is dependable and can be easily installed in HVAC equipment. However, germicidal UV light has little to no effect on chemical gases, vapors, or odors, unless paired with Photohydroionization Advanced Oxidation or PHI.

With the HVAC-PHI Cell Advanced Oxidation System,
Microorganisms can be Reduced by Over 99%

UV germicidal light enhanced with PHI technology develops an advanced oxidation reaction that destroys harmful microorg anisms. By engineering the proper UV light wavelength, the PHI Cell® provides safe and purified air.
