5 micron vs. 30 micron dust collector bags opinions?
GLitwinski
Is there anyone who has actually made the change from using 30 micron
filtration bags with one of the usual two-bag dust collectors (Jet, Delta, PSI,
etc., etc., etc.) to using 5 micron replacement bags with the same unit?
What I'm looking for is opinions based on experience with both types of bags
with respect to the amount of dust that gets through the different porosity
bags.
I just bought a 30 micron bag-equipped unit and wonder if spending another $50
on 5 micron replacement bags is worth it.
Thanks.

I switched over from the 30 micron to the 5 m on my 3/4 hp Penn State. Saw slightly decreased airflow but much less dust
in the air. Overall I'm plesed with the change.

I recently switched to the .3 micron bags on both collectors in my shop and I'm
kicking myself for not doing it long ago. MUCH less dust lingering in the air
after the collector is done running with virtually no noticable effect on air
flow. Spend the money!!!!!!

I concur. I bought the Clean Stream for mine. It was located next to a
lolly column and it used to get a very fine talcum powder like coating
on the column. No visible dust after the .3 micron bag. I'd saving up
for the shop vac filter next.

I concur with the others, the Clean Stream 0.3 micron bags work great.
Don't know How I did without it. It actually allows greater airflow (I
guess the old bag got clogged up more, even though it was rougher).
Amazingly enough, it was the best of both worlds - No dust and Lots of
Airflow.

writeup on the .3u bags that points out that they are for the top
only. What are we supposed to use on the bottom? After all there is
precious little point ins using a .3u bag on the top and keeping the
30u on the bottom! Should I use a solid (ie plastic) bag on the
bottom?

I agree about the CleanStream bags-lots less dust. Problem is this-they don't
hold up particularly well. I went through mine in less than 6mos. But thats
full days every day. I use 5microns from Oneida and they work every bit as well
as 0.3 microns. Realize that particles produced by 150grit sandpaper are
larger than 5 microns in size. Also, pharmaceutical manufacturers filter their
air delivered to filling operations down to 0,5 microns. I don't see a need for
woodshop owners to beat them.

I believe the bottom bag is supposed to be heavier and not pass any air. I
have not noticed any dust coming through mine.

Re: Follow Up Question:
You can use a plastic bag on the bottom. If you find the dust starts seeping
through your new top bag, replace the plastic bag with your old bag. If you
want performance enhancement, put a less porous bag on the bottom. I cannot
understand why someone would recommend keeping a permeable filter instead of
replacing it with more efficient media (unless the air-to-cloth ratio is too
low -- which is highly unlikely).
We sell custom made filter bags made from U.S. patented materials to filter
in the sub-micron range (i.e. less than one micron).
Remember -- too much air volume and too little filter area = dust
