Hi,

Can anyone advise of a good dust mask for spectacled DIYers? I've been
buying whatever I could find in the sheds; previously they were 3M,
this time it was something by Harris. I've been trying to cut some MDF
so I needed a mask but even adjusting the bit round the nose I was
getting my glasses steamed up. Has anyone found a make that doesn't do
this?

TIA
