MediGroup Physician Services announces agreement to bring unique CerroZone air purification technology to its members.

MediGroup, a leading healthcare group purchasing organization, will now offer CerroZone’s state-of-the-art air purification devices to its more than 25,000 members. The patented, FDA-approved CerroZone system safely harnesses powerful oxidation technology to kill 99.99% of viruses, bacteria, mold and other airborne pathogens. It also eliminates odors and volatile organic compounds (VOCs), such as ammonia and formaldehyde. 

“Over the past 20-plus years, MediGroup has grown to provide our members with the most comprehensive contracts portfolio that maximizes efficiencies and minimizes costs,” says MediGroup’s Chief Executive Officer, Andy Klearman. “We know our members will value CerroZone’s quality air purification products for their various offices and treatment areas.”

“CerroZone is proud to partner with MediGroup Physician Services to bring our proven technology to its members. This is another step in our mission to improve indoor air quality, and help keep healthcare workers and patients safe, with our first-of-its-kind air purification system,” said Susan Labadie, President at CerroZone.

CerroZone’s unique, patented technology uses internal UV-C lamps to generate ozone within a sealed mixing chamber. Air is drawn into the unit and exposed to the ozone, which deactivates pathogens, including viruses, bacteria, mold, fungus and VOCs. The mixed air then passes through a proprietary catalyst that restructures the air chemistry, converting all ozone (O3) into oxygen (O2), before returning fresh, sanitized air to the room. 

In independent laboratory testing, CerroZone recorded a 99.99%+ reduction of COVID-19 (SARS-CoV-2) virus in a single pass, in just 1.2 seconds. Similar results were achieved with other viruses, such as RNA and MS2, as well as mold and VOCs.

The CerroZone mobile unit is certified by the FDA as a 510(k) Class II medical device and complies with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 241. CerroZone also complies with UL 2998 and has Intertek’s Zero Ozone Certification, meaning ozone levels in air leaving the unit are below the quantifiable limit of detection of 0.005 ppm.
