What it is for

Used as personal protective equipment in hazardous work and for respiratory protection against dust, fumes and vapours.

How to use it

Fit it to the compatible filter with the appropriate holder or retaining ring, well centred and firmly held. Replace it when it is dirty or when breathing becomes laborious, much sooner than the filter. It stops particles only: it does not replace the gas and vapour filter. After fitting, carry out the mask's seal check.
