Half Mask Respirators
Reusable Respirators Facepieces by Fit and Compatibility
Shop reusable half mask respirators from 3M, MSA, and Honeywell for workplace respiratory-protection programs. Compare facepiece materials, sizes, fit features, and compatible cartridge and filter systems for particles, gases, vapors, or combined hazards.
A half-mask facepiece does not provide protection by itself. Use only the manufacturer-approved filters, cartridges, retainers, and adapters listed for the exact respirator model and NIOSH-approved configuration. Select the complete system for the identified contaminant, concentration, exposure conditions, and required assigned protection factor.
Tight-fitting half-mask respirators require proper selection, medical evaluation, fit testing, training, maintenance, and seal checks when used under OSHA 29 CFR 1910.134. Half masks do not protect the eyes and air-purifying models must not be used in oxygen-deficient or IDLH atmospheres.
