CerroZone Meets, Exceeds Requirements of ASHRAE Standard 241-2023, Control of Infectious Aerosols
CerroZone’s air purification platforms have become the first to meet and exceed the requirements for air purifiers set out in the recently published ASHRAE Standard 241-2023 Control of Infectious Aerosols.
The same system previously earned 510(k) Class II clearance from the U.S. Food and Drug Administration as a recirculating air cleaner for eliminating airborne viruses and bacteria. FDA approval was contingent on extensive testing at accredited independent third-party facilities.
The company’s mobile, mini and in-ceiling/wall mount units are designed to purify air in buildings such as schools, retail environments, offices and other indoor spaces. The indoor system achieved a 99% reduction of live COVID-19 delta variant in a single pass of approximately 1.2 seconds, according to independent testing at MRI Global in Kansas City.
The company also announced it had achieved Intertek’s Zero Ozone Certification. Intertek considers emissions of 0.005 ppm or less to be negligible per UL 2998, the North American industry standard for ozone testing. The unit recorded at only 0.001 ppm; five times lower than the UL 2998 standard.
In this recent set of testing for compliance with Standard 241-2023, the CerroZone units demonstrated at each fan speed, efficacy against MS2 Bacteriophage, formaldehyde safety and particulate matter count in a chamber larger than 800 cubic feet at an independent third-party laboratory – ARE Labs in Olathe, Kansas.
