If you double bag it is it better?

So currently I am running my 2hp HF dust collector out the door. I was thinking of putting something on the outlet for when I can’t do that like running late at night because of noise. (keep in mind hardly anything is coming out due to Thien baffle and what I have it connected to).

My thought is this, I have 2 bags from the stock bags that came with dust collectors. I believe they are both 5 micron. If you double bag it and then maybe sew the opening so it matches the circumference of the 5” outlet, would that work. Meaning would my effective filtering be better than 5 micron by double bagging?

its like having two screen doors on top of each other and asking if less air will pass through.

Cloth bags actually reach their maximum filtering ability after they have clogged with dust. The second bag might catch a little bit of dust that makes it through the first but probably not enough to make a noticeable difference. It might even reduce airflow.

You can buy or make a muffler for a dust collector.

I don’t think double bagging would help much
with either collection or noise.
