Paper dust masks: Also called surgical masks, these loose-fitting masks have only one strap and don’t form a tight seal to the wearer’s face. They are designed to cease liquid droplets and aerosols popping out of the wearer’s mouth, not filter the air coming in. With no filter and no facial seal, they are not designed to stop the inhalation of respirable particles found in smoke. Though they could look the same, dust masks are usually not respirators and should not be used for that purpose.
N95s and P100s: These respirators have two units of straps and type a good seal to the face. The whole respirator is made of filtering material. N95s are the most common, with P100s being more protective (much like a HEPA filter). Both types can often be present in hardware stores and other retail outlets. These respirators are licensed by the National Institute for Occupational Safety and Health (NIOSH), so look for “NIOSH” and the designation “N95” or “P100” on the respirator.

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 natural vapor cartridge, these respirators would additionally protect towards dangerous fumes and gases. Nonetheless, neither these respirators nor N95s provide oxygen.
