How many times a hour should you recirculate air in an hour?

Answer 1

The recommended frequency for air recirculation generally depends on the specific environment and its use. For residential settings, recirculating air 4 to 6 times per hour is often sufficient. In commercial or industrial spaces, especially those with higher occupancy or specific ventilation needs, recirculation of 6 to 12 times per hour may be necessary. Always consider factors such as air quality, occupancy levels, and the purpose of the space when determining the optimal rate.
