Hi

I,ve tried several face masks ( Dust ) but have yet to find one that i can
wear thats comfortable and effective. The best one ( Yellow with twin
filters ) seems to restrict my breathing. Hospital masks even when the metal
on the nose is pinched seem to be not effective for dust filtering either..
Suggestions Please!
