I use a Rigid 6 hp shop vac constantly at my work for our CNC dust control. I change and blow out the filters every week and try to reuse them as well as I can. I'll buy a new filter every 2 months roughly. After 2 weeks of use, (8 hours a day, 4 days a week) the filter has some minor dust on it but overall still good for another 2 weeks. The shop vac body is empty with minor dust on the walls and all the debris is in the bucket.
This cuts my maintenance time, and cost down a lot. With each filter $17 dollars, this will pay for itself quickly in time and lack of headaches.
I haven't tried the Dust Deputy but this does what I need it to.
Plug and Play, fits on a 5 gal bucket which I already had, comes with a hose, easy to use, easy to clean.
Hose is a little short, increases your vacuum footprint, a little wonky with the smaller hose sticking out of the top, not low profile.
