FWIW, I clean my shop vac filters regularly by simply dropping them on the pavement from 3-4’ off the ground, turning them and dropping them on all sides. Sometimes I knock them against the inside of the trash can or dumpster, which is great until you drop it in the almost empty dumpster.
You need to close the lid and walk away a couple times while the dust settles and an N95 mask is not a bad idea if you have one handy but it works great. Just takes a little patience and a few minutes and they are good as new w no water involved or compressed air. I have water, compressor and other vacuums all available at my shop and this is the method I use. You will have a nice pile of dust to sweep up if you use the pavement. Just drop it or knock it perfectly on the sides, IOW, top and bottom of cylinder hitting the surface together.
