Children sleep undisturbed as it protects them from contaminants that can aggravate or cause respiratory illness.

Auto and diesel exhaust, smoke and odors are removed by the activated carbon inner filter when you use the Model 300 and optional 12V adapter in trucks, vans and recreational vehicles.

All our HEPA Filtration Systems are U.L. and C.S.A. Approved.

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.
