RGF® Environmental Group Releases Independent Study: PHI-PKG14 PHI-CELL® Inactivates greater than 99.9% of SARS-CoV-2 Virus in the Air and on Surfaces

February 25, 2021 / Press Release

  • PHI-PKG14 PHI-CELL® product with Photohydroionization® technology inactivates greater than 99.9% of SARS-CoV-2 virus in the air on inoculated surfaces
  • By actively treating the air inside the occupied space the PHI-PKG14 PHI-CELL® eliminates the need for virus particles to travel through the HVAC system filters or UV air purification system
  • Versatile magnetic mount installation for packaged units and air handlers up to 250 tons
  • Independent, third-party testing provided by Innovative Bioanalysis


Port of Palm Beach, Florida (February 26, 2021)—RGF® Environmental Group, Inc., a leading environmental design and manufacturing company, has released the results of an independent, third-party test that indicates the PHI-PKG14 PHI-CELL® product with Photohydroionization® technology inactivates greater than 99.9% of the SARS-CoV-2 virus in the air and on inoculated surfaces.

SARS-CoV-2, commonly known as coronavirus, is the virus that causes COVID-19. Given the CDC’s determination that SARS-CoV-2 is an airborne virus, meaning it spreads from person-to-person via aerosols and respiratory particles, the test results are important for building owners and operators seeking a proven solution to combat SARS-CoV-2 in the air and on surfaces inside the occupied or air-conditioned space.

“SARS-CoV-2 virus particles or aerosols are produced when an infected person coughs, sneezes or talks. Large virus particles fall out of the air and onto surfaces, resulting in surface contamination, however small virus particles can stay airborne for hours,” noted Dr. James Marsden, Executive Director of Science & Technology at RGF® Environmental Group. “Similar to RGF’s REME HALO®, the PHI-PKG14 PHI-CELL® neutralizes greater than 99.9% of the SARS-CoV-2 virus in the air and on contaminated surfaces.”

PHI-PKG14 PHI-CELL® product with Photohydroionization® resulted in
greater than 99.9% inactivation of the SARS-CoV-2 virus within the
occupied space at 36″, 72″ and 84″ distance from the PHI-CELL®


Testing Protocols and Results
Testing was performed at the Innovative Bioanalysis Laboratories in Cypress, California. RGF’s test procedure used the SARS-CoV-2 virus inside a large chamber (1,280 cu. ft.) representing a real-world air-conditioned office or home. The virus was nebulized into the space simulating a sneeze or cough from an infected person. With the PHI-PKG14 PHI-CELL® operating inside the chamber, the virus was reduced on contact, resulting in a greater than 99.9% reduction of the virus within the simulated real-world space at 36″, 72″ and 84″ distance from the cell.

Testing of the PHI-PKG14 PHI-CELL® active air purification system indicated that the SARS-CoV-2 virus is significantly neutralized within the occupied space, and significantly reduced risk of person-to-person infection by respiratory particles and aerosols. The PHI-PKG14 PHI-CELL® eliminated the need for virus particles to travel through the HVAC system filters or UV air purification system.




PHI-PKG14 PHI-CELL® Product Overview and Applications
PHI-CELL® technology to actively treat the air inside conditioned spaces. This product is specifically designed for package HVAC systems. Because of its versatile magnetic mount installation, the Package PHI Unit can be used in a wide variety of applications. Adjustable magnetic feet attach without fasteners to the blower unit, simplifying installation. The Package PHI Unit is effective where ductwork is difficult to access or where modification to existing or HVAC systems is not an option. The 24V model connects directly into the control box of the HVAC unit where the 14” cells can handle package products up to 20 tons. These units can also be used in conjunction with RGF’s new PKG Rack™ system enabling installation for up to eight package units in one application.
