Review on Dust-proof Chemical Compatible Respirator Cartridges: Occupational Health & Safety Products for Personal Protective Equipment by Nate Nelson

I smudged the swedish finish thought it wouldn't work so I took the mask off I couldn't tell, with or without the mask that says me got what i'm used to swedish finish so i put my mouth on the filter cartridge and inhaled, very little resistance, i compared it to my 3m filter, 3m has more resistance, i shared it. , it has charcoal, same as 3m, but it has big granules, it doesn't even look like it logically filters vapor from the air, it doesn't work, I would say don't buy this product, it is a risk to your health , Revain must remove this product ,
