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.
