Thank you for the timely reminder and for the great suggestion of
dating the replaceable filters.
I’d like to add that I’m in the process of switching over to
disposable N-95 rated surgical facemasks for some uses. Particularly
if you’re ill, these can be a way to prevent continuous re-infection.
Additionally (and the big plus for me), they are available with the
attached face shield (clear plastic) that comes “up” from the mask to
protect the eyes against splashes, flexshaft dust, and little parts
that go flying around.
They’re available in most good dental and surgical supply catalogs
and run about $1 - $1.50 each (sold in boxes of 25 - 50 depending on
I’m using them for routine uses like polishing, investing,
quenching, grinding, enamels, etc. They’re not fume-specific (I don’t
think), so I wouldn’t use them for heavy duty etching with nitric or
that type of thing.
