For most applications, the manufacturer recommends 6 Total Air Changes Per Hour.
•
Total Air Changes Per Hour = Air Changes provided by HVAC Air Changes provided
by in room Air Purifier.
Note: The air changes provided by HVAC system will vary throughout the year. Normally, 100%
recirculating HVAC system will provide more air changes per hour during the summer and winter, and
fewer air changes per hour in the spring and autumn. Systems that have mixed outdoor air and
recirculating air will have more consistent air changes throughout the year.
