 Air Changes per Hour (ACH)

(How many times can all the air in a vehicle/area/room be cleaned through the filter each hour?)

Based on 8' ceilings

Generally speaking, the more air changes per hour (ACH) you can provide, the more effective a HEPA filter can be.
1 ACH provides excellent air cleaning results (higher is recommended for people with sensitivities).
Remember: More HEPA is better than less, but some HEPA is better than nothing at all.
