N99 Disposable "Particulate" Respirators
Particulate
respirators are also known as "air-purifying respirators" because they
protect by filtering particles out of the air you breathe. Workers can
wear any one of the particulate respirators for protection against
diseases spread through the air - if they are NIOSH approved and if
they have been properly fit tested and maintained.
N99 Filters at least 99% of airborne particles. Not resistant to oil.
