I’ve managed to fill my dust collection bag to about 40% and am about to empty it out. so i’m thinking if i should wash or otherwise clean out the big filter bag that hangs on top of the unit. what do you all do? wash it, vacuum it? other?

Hopefully, there won’t be anymore emptying the chip bag for me. I am using a trash bag and so far, no problems. The bag is the contractor’s 42 gallon type bought at Lowe’s. When it needs changing, I just remove it, close it up and install a new one. :-)

The bag filter gets a good whooping daily with an ugly stick. :-)

Here is a link to my post.

Note: I still have to finish the inside of the Thien style chip separator for the drum. That should eliminate most of th chips/dust collected in the trash bag. A Wynn filter is also on my wish list.

Don’t wash it! You can clean it with it still installed and the plastic lower bag in place by blowing compressed air through the bag, the dust will fall into the lower bag. I would recommend that you ditch the cloth bag and get a Wynn filter to replace the cloth bag. Here is the website

The cloth bags are very inefficient and allow very tiny dust particles to get through the bag. It’s the dust you cant see in the air that is exhausted through these bags that does harm to your lungs.

Just remember that on most bags the dust cake that forms is actually part of the filtering system. Remove it, and you remove some of the filtration. If it hasn’t reduced air flow dramatically, I would fool with it. If it has, it may be time to take it outside, hang it up, and beat the snot out of it with a 4’ long 1”+ dowel.
