Honeywell HPA200 is a magnificent air purifier for medium-sized rooms. It’s appropriate for bedrooms, living rooms, even a kitchen about 310 sq ft in size. The True HEPA filter, coupled with odor-reducing Honeywell A or A+ pre-filter, removes the small as well as large particles and undesirable odors. Hello Linda, it depends on what the ACH (air changes per hour) requirement is by CDC. Usually, 5 ACH is recommended for allergy-prone people. The total volume of the classroom is 30*40*30 = 36.000 ft3. HPA300 has a 300 CFM airflow; that means that it cleans 300 ft3 per minute, or 18.000 ft3 per hour. In short, if the requirement is 1 ACH, you would need 2 HPA300 due to very high ceilings. If the requirement by CDC is 5 ACH, you would need 10 HPA300. Hope this helps. Reply Prepare to be confused.

This helps in energy saving because it’s only in use when you need it. ii) Air filtration performance
