Types and Protection - As defined
by OSHA
 Air-Purifying
Respirator: A respirator with an
air-purifying filter, cartridge, or canister that
removes specific air contaminants by passing ambient
air through the air-purifying element.
 Dust
Mask: A loose fitting mask that covers the
mouth and nose often made from a thin material to
filter larger dust particles.
High-Efficiency Particulate Air (HEPA)
Filter:
A filter that is at least 99.97%
efficient in removing monodisperse particles of 0.3
micrometers in diameter. The equivalent NIOSH 42 CFR
84 particulate filters are the N100, R100, and P100
filters. |
Protection Factors:
NIOSH Definitions
Assigned Protection Factor (APF): The
minimum anticipated protection provided by a properly
functioning respirator or class of respirators to a
given percentage of properly fitted and trained users.
Simulated Workplace Protection
Factor (SWPF): A surrogate measure of the
workplace protection provided by a respirator.
Workplace Protection Factor (WPF):
A measure of the protection provided in the
workplace by a properly functioning respirator when
correctly worn and used.
Selecting a Mask
When purchasing a mask look
at the label on the package, select the type of protection
based on the type of work you are typically doing.
