I have a few masks for DIY work bought a good few years ago. Long
since lost the specification, so don't know whether they are suitable
for blocking the virus or sneeze-spray, although I would argue that
any mask is better than none. They are valved masks, which are
supposed to be better for people who wear glasses, but even so, and
even squeezing the malleable strip down onto the bridge of my nose, I
still get a lot of exhaled breath coming up inside my glasses and
fogging them.

Can anyone recommend a mask that doesn't do that? Also being suitable
under the present circumstances would be a bonus.

For DIY I normally recommend:

They can be adjusted to get a very good face seal (although beardies may
have a different experience), and the valve directs the hot wet air down
and away from the eyes. They are intended to last a month of daily use
before being replaced. That usually translates into much more time with
occasional use.

If you want protection from the current "elevated" threats, you would
probably have to consider the re-useable full face mask version with the
appropriate filters.



That's what I've been using for a year or two (after a recommendation
here) and, as a beardy, can report that they work well. I've had to
replace the elastic once, and wipe the inside with IPA from
time-to-time, but the input filters are unlikely to get clogged so I
don't see why the mask can't continue to live until the exhaust valve
gives-up.
