So every time I turned on my dust collector, it would put out a puff of dust that reminded me of Pig-Pen from the Peanuts cartoon. I believe it was blowing more dust back into the shop than it was keeping in the collector. Therefore, I wanted to upgrade the filter to something that would do a better job.
My dust collector is an old Delta Shopmaster model AP400. It has a 1HP motor, and the best information that I could find on it stated that it came with a 50 micron bag, which probably accounts for all of the dust that was escaping.
I decided that I wanted to upgrade it to a cartridge filter and a plastic bag, and I found the parts that I needed on Wynn Environmental's website. I contacted Wynn Environmental to see what they recommended for my collector, and they offered me several options. I ended up going with the 35BA222NANO Cartridge Kit. This cartridge will filter down to .5 microns, which is 100 times better than my old bag, literally!
Because the cartridge was not designed to fit my collector, the folks at Wynn Environmental sent me an experimental gasket and mounting kit, in order to see how well we could retrofit the 35BA to my unit. By the way, it worked great.
So anyway, this tutorial is not so much of a step-by-step how-to. It's more of me showing pictures of the process with a short comment under each picture. (Click the pictures to see the comments.)
Here's some specific information about my upgrade:

All of the parts that I used came from Wynn Environmental except for the carpet tape and inner-tube.
