IH: Face masks for smoke not as helpful as you think
Interior Health says using face masks to find relief from the wildfire smoke may not be as efficient as you think.
The Authority says it's gotten many inquiries about it, and wants to re-iterate that paper dust masks don't do anything to block particles found in smoke.
Certified N95 respirators are what you're looking for, though they have to be properly fitted by a professional, and aren't made in versions small enough for kids to wear.
It also makes breathing more challenging, and the filter can stop working if its saturated with water or sweat.
IH says in general, it doesn't recommend the use of these masks unless it's for someone who has to work outdoors.
They say the best protection against smoke is just to reduce the amount of time you're directly exposed to it.
