Did you see the wildfire smoke dust on your face mask when you wear it? Our nose mask catched the wirldfire smoke! July 31 2023, 0 Comments
I weared the HEPA filter nose mask during the time Toronto had a blanket of wildfire smoke. There is dust on the face of HEPA filter (left one) , the right is a a new one .
The more dark position on HEPA filter are face to the holes on nose mask front cover.
The HEPA filter is more dark on the back side in below photo. We catched the wildfire smoke since our nose mask no air leaking. Our nose mask blocked the dust and odor from the wildfire smoke.
The wild fire smoke is on surface and inside of the HEPA Filter.
