Performance of HEPA N95 Nose Mask after 60 days used in Toronto, Canada June 05 2022, 5 Comments
N95 HEPA filter can clean air to keep you health!
I replace the N95 HEPA Filter after 60 days in Torotno, Canada. It is dark on used HEPA fiter in photo.
The left one is a new filter, view from back side
The top one is used HEPA filter, view from front of filter.
I wear the nose mask to super market, watch circus, ride TTC, meet clients, etc.
I feel it is very comfortable with no fog on my glass, easy to breath with fresh air.
