Hi Bill - Here are a few options which I have been exploring which may be useful?
I have a
Trend Airshield and have also tried the
JSP and although both are great at what they do, I find them cumbersome and also expensive to maintain as regards batteries and filters etc.
At the simplest level you could try the
Dust Bee Gone available from many outlets including
Turners Retreat. This is a simple but ingenious washable face mask (designed for woodturners) as recommended by my woodturning tutor.
However, I am currently using a
3M™ 7500 Series Premium Comfort Half Mask which is re-usable and for which there is a range of filters including vapours and gases (useful for vapours produced by Pyrography?), as well (of course) as dust. The mask is re-usable and replacement filters are relatively cheap. The mask itself is cheap (especially on ebay) and uses a simple exhalation valve system (no electric fans involved). This is working well for me.

HERE3M also do a full face version
3M™ 6000 & 7000 Series Full Face Masks - using the same filter system (no fans). I haven't tried this, going for the simpler (and cheaper!) half mask system which fits OK underneath my head visor.

HERE3M also do a fan powered helmet which I haven't investigated (as the
Trend &
JSP are probably cheaper?). However, just for completeness, info on these 3M powered respirators are available
HERE.
Hope this helps?
