I have three collectors. The four bag Jet got modified by swapping the bottom bags for plastic bags. A small hole in one dusts the shop well. I also swapped the top. Originally, it had something in the area of ten micron bags. I couldn’t see what they allowed in the air, but, over time, the dust in the immediate area would build and the bags always had a good layer on them. After swapping to one micron bags, there was a HUGE improvement.

Even before I installed foam (the type you use to mount pickup campers) around where each bag attached to the collector and though you could see the dust trails, it wasn’t nearly as bad as what the original bags, or a hole in a bag did.

My horse and a half Jet has a canister and doesn’t pose any problem, unless I puncture the bottom bag. Then hell comes back.

I bought a Delta one horse for an experiment. It had the worst bag of the bunch. I could all but see the dust pumped in the air. Someone posted a deal on the deal forum here and I replaced that bag with a one micron. That changed the game completely too. Just for reference, I used the old bag to hold cheap bags from the big box (to contain them and protect them from being even looked at, for fear of a puncture). It became a keeper, but I sold it to my buddy and replaced it with a HF “2” horse, which I also replaced the bag on and, again, used the original bag to hold big box clear lawn bags.

In short, if you have a dust storm, it’s probably a small puncture. Even an eight of an inch will dust you out when you have a lot of fines.
