They should be computed by an hvac cleanroom expert as many aspects must be taken into consideration such as the size of the room the number of people in the room the equipment in the room the processes involved the heat gain etc.
The above suggested air changes per hour are only a design rule of thumb.
High pressure air in clean areas prevents dirty air from leaking into the cleanroom from adjacent.
