Recent Study Finds HEPA Filters Reduce Particle Pollution by 60%
A recent study conducted by Dr. Ryan Allen of Simon Fraser University and colleagues demonstrated that using portable high-efficiency particle air (HEPA) filters can reduce the presence of air particles by about 60%. This in turn resulted in decreased presence of some cardiovascular risk factors leading the researchers to conclude that filters would help reduce cardiovascular morbidity due to wood smoke.

This may help communities mitigate immediate indoor air health concerns. We hope to have two focused webinars on health effects related to wood smoke within the next few months. Please let us know if you have suggestions or requests for the webinars. Also, if you know of other recent health studies, please include the link as a comment. Thanks!
