Shop vacs don't last long when used as a dust collector on a media blast cabinet. You should think about tying the shop vac into some kind of a water trap to keep the grit out of the vacuum.
Do a search here and on the net; there are a couple of good designs out there that are cheap to make using a 5 gallon bucket and some PVC pipe.

Gotta be more that that. For one, I'm pretty sure they don't both use water.

My bead blast filter cabinet using 6' tall filter tubes, no moisture anywhere near the filter.
They do sell for about a grand though. High end for daily use.

I use my 6.5hp commercial shop vac with a 6' or 8' 2.5" hose. I have been using it this way for a few years, enough hours to replace the glass window three times now. Never had a problem.
I recently picked up a 5hp wall mount shop vac with a smaller 1.5" hose and it doesn't flow quite enough air to evacuate the dust as much as I am used to, so I have gone back to the 6.5hp unit

I buy the bags that fit inside my Ridgid shop vac. They're expensive, but they do last a while and keep most of the fine dust out of the filter and motor. I also have a water trap that I rigged up, but haven't hooked it back up again... I take it out during the winter since the water tends to freeze.

we've had good luck with a shop vac that has an inner bag and hepa filter. You will replace them every few 20 to 50 hours but broken silica is highly carcinogenic in the lungs. We've found some blast cabinet makers sell a shop vac with bag and hepa filter as their inexpensive solution for cleaning blast air. An alternative is a high end bead separator system which can be expensive. If this is a hobby thing then you are fine with the inexpensive solution but if you will be beading 8 hours a day / 40 hours a week you need a commercial solution or bags, filters and beads will get expensive.

I built a small enclosure to house a shop vac-type HEPA filter and put it between the blast cabinet and the shop vac. So far it has lasted about 7 years of intermittent blasting and the vac is a HD cheapie, throw away type
I have tried several different ways to clear the dust from my blast cabinet. The best way I have found is a blower motor that I got at Granger. It is an inline duct motor that goes in a 4" exhaust. I mounted this on the side of my cabinet and I vent it through the wall with a dryer exhaust connection. It moves just the right volume of air, your blast glovers will not **** straight out yet it moves enough to clear the cabinet. I bought a wall mounter vaccuum from some vendor at the EAA convention a couple of years ago and still have it hanging on the shop wall but have only used it a couple of times because it is so much louder than my set up. I would sell it if you are interested.

Here is a link to a thread I did on my home built cyclone dust separator for my blast cabinet. There is a link at the end of the thread showing the finished unit mounted on the cabinet. I originally tried a squirrel cage blower, but found that an impeller at 3500 rpm was needed to do the job.

I use a typical small shop-vac with a 1 1/2" hose, and I stop and knock the dust out of the filter about every 1/2 hour of blasting, and its worked for about 2 years. I also wrap a ***** hose type of cloth around the outside of the filter, it catches lots of dust. I don't blast much, but I do take every precaution to help out my equipment.
