HEPA H11 Nose Mask performance during my packaging work with heavy dust of carbon July 05 2023, 0 Comments
I wear my HEPA H11 nose mask to make a small 750g bags of pellet carbon from 25kg bag. There are dust in the air during packaging. I change the filter every half day. The HEPA filter can block the dust of carbon and keep the nose clean.
I used 8 HEPA filters to fill the carbon into small bags and sealed 2780 bags. I accept this order because I have the nose mask.
The nose mask has advantage in no leaking and brock dust is very important. The nose mask has brocked the wildfire smoke, too.
