Air filter masks not effective for wildfire smoke, says doctor

May 30, 2019

Smoky haze blanketed much of southern Alberta this morning as wildfires in northern Alberta continued to grow. The air quality in Lethbridge scored a 3, or low-risk on the Air Quality Index, but is expected to climb up to a moderate-risk later this evening. Doctor Lizette Elumir with the Alberta Health Services says that those who wear air filter masks are getting little-to-no benefit from them.
