I think I read somewhere that dust masks don't work if you have a beard.
Is that correct and if so what's the best solution?:)

Shave it Off.
only kidding.
Buy a Triton

A proper mask held under pressure should work ok for everything other than extremely fine particles (mdf and asbestos). It is not suitable for use with smoke/fumes or solvents. As Stuart said, you may be better off wearing a Triton lid.Quote:

Your only alternative is a positive pressure system (PAPR or supplied line) where an excess of filtered air blows past the face seal thus preventing dusts from entering.
This can be provided by any respirator which uses a battery powered fan/pump or an air line system attached to a dedicated compressed air source. Note your shop air compressor, unless its an oiless system with appropriate filtration is not suitable.
The Triton respirator displays an AS1716 approval but I believe it can only be used for P1 level contaminants - timber dusts and similar. If you need to provide protection against smoke, fumes or certain gases (P2/P3 organic/inorganic toxins ie 2 pack paints) I would recommend a more professional level of respiratory protection.
Thanks Mark and the rest of you for that. I'll investigate
Triton.
