Simple paper dust mask is leaky and uncomfortable for me, and the leaks also
fogs up the goggle.
Powered respirator (PAPR) cost too much. Is there a DIY plan for making one?
It looks like some sort of fan plus a dust mask should do the job. Picking
the right fan and dust mask is the tricky part.
I think I could come up with something involving a windowbox fan, some
leftover plexi, a few feet of shop vac hose and a long extension
Want me to give it a try over the weekend?
Spend the money, if you make your own and it doesn't work - you could die.
Simpler still, buy a new sander with dust collection. I never wear a mask
and never deal with dust any more. Festool has several affordable sanders
that fill the bill. Of course a quiet vac works wonders with these sanders.
Absolutely true! I dealt/put up with dust for almost 25 years. Finally I
added a dust collector. The Domino requires a vac to be collected to
properly evacuate the mortises that it creates so I took advantage of the
substantial discount by buying the Domino, Domino assortment and Vac all at
the same time, a big pill to swallow but about $200-$300 less expensive that
way IIRC. Any way with the combination of the dust collector and the
Festool vac creating less mess and greatly easing clean up, I got used to
the cleaner working environment rather quickly. Then I decided to retire my
15 year old PC right angle ROS and SpeedBloc finish sander with the Festool
Rotex and Festool finish sander. Wow, no more sanding dust. I had no clue
that the dust control on these sanders would be that good. It tool me quite
a while to trust that the sanders, especially the finish sander, were even
working. "No dust" is deceiving. Knowing when to change worn out sand
paper is a bit tough also. Worn out sand paper looks like new sand paper,
you have to feel the paper with your finger to know when to change it.
Fortunately the paper lasts even longer because it does not get clogged.
Had I known how effecient all of this dust control/collection worked I would
have made the switch many years ago.
Yup, been there - even worse if, like me, you have a full beard and
Yes, powered respirators are expensive but they work.
I spent a while thinking about it then decided the only thing to do was to
"bite the bullet". I was also "encouraged" by one of my daughters who
works in "respiratory investigation" at a large hospital and another one
who is a radiotherapy technician, treating cancer patients.
They are properly tested and rated for the job. I have read safety reports
on "simple paper" dust masks and you might as well not bother. Most of
them are rated "for nuisance dust only" and are not suitable for anything
harmful. Particle size is also very important. Wood dust is carcinogenic,
some woods worse than others and MDF, if you use it it, worst of all.
Get yourself a proper mask, rated for MDF, and won't have any health
problems in the future.
Look at it this way, a decent mask will probably cost you less than the
first consultation with your doctor, never mind the treatment.
