If you are trying to keep the harmful dust out of your lungs it is a waste
of money. No repeat no DC will get the sub 5 micron stuff out of the air,
The ones that say they will remove down to 3 microns will do so after the
dust has caked on the filter so almost NO air can get through. That is the
reason that commercial shops have the DC venting outside. If you can see it
it, is not dangerous but under 5 microns the lungs can't expel it.
