Paper mud masks: Additionally called surgical masks, these loose-fitting masks have only one strap and don’t kind a good seal to the wearer’s face. They’re designed to cease liquid droplets and aerosols coming out of the wearer’s mouth, not filter the air coming in.

N95 particulate filters or purple (P100 or HEPA) filter cartridges will protect towards particulates in wildfire smoke. When used with a combination filter that has an organic vapor cartridge, these respirators would additionally protect in opposition to harmful fumes and gases. Nonetheless, neither these respirators nor N95s provide oxygen.
