I just got an email scolding me for burying this tidbit in another thread, so am putting it up here.
Rather than buy the Jet cartridge retro-fit kit, an alternative is to simply make your own. To do so you need one of the special wide pleated filters designed to handle lots of dust and airflow. Most fine cartridge filters are setup where they need a cyclone or prefilter, so you need the right kind. The right ones have about half the total filter area and are coated with a release agent that lets the dust fall right off as soon as the airflow stops. A couple of taps and it is ready to go again.
They make these in paper poly combinations, but the result can not be washed so is only good for a few years. You also can buy them in all spun poly that are good for four plus years as they can be fully washed to bring them back like new.
The one I have is from Wynn Environmental Filters (http://www.wynnenv.com/torit_filters.htm) Part number 2A100SBOL for $126. This one has a good bottom seal, so you don't need to modify a thing or make any special adapter for it to work on most dust collector bag trees.
Ideally you should have a filter with an outer expanded metal screen but no inner metal (unlike mine), the wide pleats, a top with a hole, the release coating, and 100 to 125 square feet in a 12.75" diameter 26" tall unit or there abouts.
And yes, I know it would be better with my filter that has the inner metal if I made a canister to sit on top of my DC. Doing so has some advantages, but is more work. The canister would push the air through the filter the way it was designed to work and put all the dust on the outside making for easier cleaning. The trade off is more work building and sealing a canister, versus more work cleaning your filter without the canister. With the canister around the filter, cleaning becomes a simple matter of blowing air (not too much pressure or will ruin the filter) through the open top hole with all in place. The dust will fall right into the bag below.
In any case,

To upgrade my Jet DC-1100 took about five minutes. I only needed: [list=1]
That filter;
A 28" long 1/4"-20 threaded Rod;
A nice looking threaded knob for the top of the filter;
A couple of nuts with lock washers to secure on each side of the cross bar; and,
Some poly bags to replace the lower collection bag.
[/list=1]

The result works like a champ and only cost $5 plus the filter.

For those on a tigher budget, you might want to consider the Farr Model STXL-110 121884003 34" Tenkay Spun Bonded Polyester 106. Go to http://www.camfilfar.info/rep_locator to find a distributor near you. Alternatively, call Farr in Ottawa to get a local phone number: Camfill Farr, Old Innes Rd., Ottawa, Ont., Tel: 613-521-5555 or just order from them direct plus add shipping and taxes With this one, you might have to do some modification to the filter top to make it fit.
Is this what I do? Maybe for a roll around, but I really use Terry Hatfield's DustEliminator Cyclone (http://www.dusteliminator.com) with a couple of fine 226 square foot filters powered by a nice Leeson 5 hp compressor motor.
Hope this helps.. and not part of any of these firms..
