The chart below is to be used for reference only and shows the CFM required to meet number of air changes per hour (# ACH) based on a room size.
For example, an ACH of 6 for a 20x30 room with a 10ft ceiling requires 600 CFM. One CRYSTAL-AIRE®uv unit set at speed 3 will deliver 600 CFM and achieve the desired room ACH. Maximum room size for CRYSTAL-AIRE®uv: 48,000 ft3 (60x80x10ft; max. airflow @ 1 ACH).

Parker Launches a High-Efficiency Ultraviolet Air Purifier, CRYSTAL-AIRE®uv
Lancaster, New York, April 20, 2021 – The Industrial Gas Filtration and Generation Division of Parker Hannifin Corporation, the global leader in motion and control technologies, today announced a portable system that uses advanced filtration and irradiation technology to purify the air for indoor spaces. The combination of ultraviolet energy and True-HEPA filtration captures, irradiates, and filters bacteria, dust, mold spores, odors, and virus particles as small as 0.3 microns which is about 250 times smaller than a human hair.
