Reply to comment by the_GOAT_44 in What can I buy to get rid of dust? [Please Help Me] by admiralamott

I tried it both ways at first and found it quieter , basically muffles it a bit. I will however check the filter surface when I eventually replace them to confirm, if the output filter is clean I will just reverse them. I am guessing probably good for a few months.

Don't put the input filter on the output, you'll just end up blowing the dust back out of the filter. Just throw it out and use your output filter as the new input filter. Don't bother with an output filter anymore.

Also, it's quieter with two filters because of course it is. It's blocking the air and also blocking the sound as well. But it's really just doubling the resistance to the whole system without providing any meaningful increase in filtration.
