User Instructions
to clean the shell.
b. Do not store in direct sunlight.

User Instructions
to clean the visor.
Cleaning
The M-Series Headgear should be regularly cleaned. Follow the hygiene practices established by your
employer for the specific contaminants to which the respirator assembly has been exposed. Contact 3M
Technical Service for additional information on cleaning the M-Series Headgear.
• Headgear Shell, Visors, Visor Frame, and other plastic parts:
A clean cloth, sponge or soft brush
dampened with a mild solution of soapy water may be used to wipe down the M-Series visors,
headgear shells, head suspensions (including the webbing), and all other plastic parts. Rinse with
clean water. Washing temperature should not exceed 120°F (49°C). Rinse with clean water. Air dry all
parts inside and out thoroughly before storage or reuse. If liquid enters the air channels ensure it is
thoroughly dry before storage and reuse.
Do not use strong solvents for cleaning plastic parts including headgear shells, suspensions, and
visors. To help prevent build-up of paint overspray or other contamination on visors, 3M recommends
use of the visor peel offs (M-926 or M-928). To help keep the headgear shell clean, 3M recommends
the headgear cover (M-972) or head, neck, and shoulder cover (M-976).
• Comfort Pad:
The forehead comfort pad/sweat pad (M-957) may be hand washed or laundered with
a solution of soapy water.
•
Faceseals, Headgear Cover, and Head, Neck, and Shoulder Cover:
The fabric faceseals,
headgear cover, and head neck and shoulder cover are intended to be disposable. No cleaning is
recommended. Cleaning the flame resistant faceseal (M-937) or Headgear Cover (M-972) may result
in a loss of flame resistant properties.
•
Shrouds:
M-445 Standard Outer Shroud: This shroud is generally considered to be disposable and should be
replaced when worn, damaged or soiled. A clean cloth or sponge dampened with a mild solution
of warm water and liquid household soap may be used to gently wipe down the outer surfaces
and the shroud gasket. Thoroughly air dry before storage. If deciding not to treat the shroud as
disposable, as suggested above, inspect closely before reuse.
