With a standard ceiling height of 3 meters, 150 m³ of air needs to be cleaned. Two home units with a capacity of 46 m3/hour provide an air disinfection cycle of almost 3 hours. The APS-300 or APS-200 are perfect choices. Alternatively, the new high performance HD series, which is quieter due to the protection of the reaction chamber and the insulation of the machine, is absolutely suitable for continuous air disinfection of rooms of this size.
