realize that you may have hung this already since the post about 3 weeks old. However, since I bought my air cleaner I have hung it using S-hooks/eye bolts and vacuum cleaner belts (the round rubber belts). This serves at least 2 purposes. One is that it allows for some flexibility on the placement of the bolts/S-hooks since the vacuum cleaner belts are flexible and stretchy. Secondly, the belts dampen any vibration of the unit (which admittedly is not much). Anyway it's worked for me for 25 years. I think I've replaced the belts once, when I moved it to a different ceiling location in the shop, but I don't think it was necessary to change them even then.
It's worked extremely well for me on the ceiling. The only issue with all of these (and mine is a JDS) is that the filtering is not at the HEPA level. The only air cleaner made by a woodworking related company that is HEPA is the most recent Powermatic addition. It can also be hung from the ceiling. I did buy this Powermatic unit, but I have kept my old JDS in its place and mounted the Powermatic on wheels so that I can keep it close to where I am working; tablesaw, bandsaw, router table, sanding, and lathe. I realize that having 2 of these units might be overkill but I have always believed you can't underestimate the need for maximum dust collection, so I have a cyclone for large machines, a HEPA vac for sanding and smaller power tools, and the air cleaners for overall filtering. It does work and, as long as I don't forget to turn them on, very little dust settles on anything in my shop. I also use a HEPA powered helmet, mostly when turning, but other times as well. I never find any fine dust in my nasal passages, as sign at least to me that it's all worth it. I feel my lungs are as safe as possible.
