Performance of N95 HEPA filter Nose Mask May 14 2021, 4 Comments
The performance of nose mask is much better than face mask in sealing.
1. I wear the face mask to packaging GAC into 720g bag, there are a lot dust going through the gap between the nasal and mask. The dust of activated carbon is black you can see it in photo
2. I wear the N95 nose mask to do same works this week. The dust is filter out, I breath clean air this time. I am very happy with my Nose Mask's performance.
I wear nose mask for 6 hours, there is no dust in nose at all!
The N95 HEPA filter brock the dust!
The inside of the nose mask is very clean, no carbon dust.
