I have a Jet Vortex 1100 DC with the canister-style filter. How frequently do these need to be replaced or cleaned more than spinning the insert?

Well, I’m sure it will vary quite a bit between woodworkers. I replaced the one on my Oneida after 6 years. The way I determined it needed to be replaced was with a gauge I had mounted on the DC. I used it to judge when I needed to clean the filter, after cleaning it the back pressure would drop to about 2”. When it got over 4” I would clean it. It got to the point when cleaning didn’t allow the back pressure to drop more than maybe an 1” or so….that’s when I replaced the filter. I’d say it’s anybody’s guess when to replace without some sort of measurement arrangement. Another good way to do it would be to gauge the air at a blast gate, but to me the bottom line is when you can’t clean it anymore you need to consider a replacement. BTW, my cleaning was never spinning a flapper. I blew the dust in from the outside while mounted on the DC using an air hose (and being careful). Then I dismounted the filter and laid it on it’s side on the floor. Lifting each end about 18” I would drop….several times while rotating the filter around. Stand it back up and let the dislodged debris fall to the floor. Lastly I would take my shop vac and suck whatever was left from the inside…then remount it.

That’s a good question—I’d like to know the answer too. I remove mine periodically and clean it out the best I can using compressed air (blowing from the outside toward the inside). It’s amazing how much fine dust is captured in the pleats. The dust is literally like talcum powder.

Compressed air makes sense.

I removed mine and knocked it a few times on the ground (by the way, it create crop circles in your lawn). I think that Mahogony and MDF are to blame for a lot of the think and fine dust.

My DC is working well. Fred’s compressed air method sounds like a great start.

Curious if taking a hose to it would be the death of it?

Some of them can be hosed out (as I understand it) but none of the ones I’ve had (an Oneida, one from Penn State and the ones I now use from Wynn. So it would pay to ask the manufacturer. It does seem to me that the finest dust is the worse….I think mine suffered what might be an early death because of heavy drum sander use.

Jet’s manual reads: To clean the filter, turn the handle a couple of rotations so the dust falls into the collection bag.

Well, that is not good enough.
