Ok here is some info few have posted. it is not just the size of the
particles
the bag will fillers but how big the bag is. this is a key issue. the
bigger the
bag the better. if the bag is big enough to pass the air with little
resistance
you will get far better filtering then if you use a smaller bag or even
one that
goes down to a lower micron.
this is one of the best places to get a bag
http://www.americanfabricfilter.com/
you can get very good filtering if you do it right. I was getting pretty
good
filtering on my big bad on my cyclone if I kept it clean. far better then
I
would have with a smaller bag. if the air flow is restricted it pushes the
smaller particles out of the bag.
you also need to shake the bag often. aleast once a day.

If the bag is big enough, you never need to shake it, nor empty it as it can
contain everything. One might even muse that the universe is mother nature's
dust collector bag.
