   Pick up a squirrel cage blower/motor from an HVAC shop. These are readily available as they are always changed out when a home furnace is replaced. They usually have most of the life-cycle remaining and a lot of shops will give them away. Clean up the motor, give it some lubricating oil, build a plywood box with the intake sized to take nested 16 x 20" or 20 x 20" 3M filters, hook it up to AC and you're in business. The whole thing will set you back less than $100.

   Depending on the size of the pulleys you use this setup will filter the air in a 20 x 20' x 8' shop several times per hour.

   I bought a small Grizzly http://www.grizzlytools.com/products/Hanging-Air-Filter-w-Remote/G0572

   Like the remote and timer feature myself. Plus the interior filter is more like a DC filter that will trap smaller (1micron) particles. I used a ladder and some horizontal braces and hucked it up onto the braces. Then used some more to shim it to the ceiling and screwed it off to to two joists. Works great and I would buy it again. My shop is the same size as yours. Just orient the thing so that it encourages a circulating airflow. My inlet is above the sanding area.... the most noxious place.

   Dennis, it's been awhile, as far as I know, since anyone did a thorough comparison review of air filters.  JDS <click> makes very good air filters.  Jet and Delta performed pretty well in the testing I relied on to make my choice, and said they were going to improve on the area(s) of weakness that showed up in the tests.

   Thanks for the reply.

   Which one did you buy? The JDS is $320 & the Jet is $205 (after the rebate of $25)

   I'm leaning towards the Jet, it gets very good reviews on Amazon, & I can't ignore the $85 savings

   Thanks

   Dennis

   Dennis, I got extreeeeeemly lucky and found a "new in box" JDS at a woodworker's estate auction, for $75, lucky because that's the one I wanted!  You'd probably be just fine with the Jet.  The differences in that older test weren't that great.  I found a late-2006 review in my magazine stash which had similar tests to the one I read ages ago.

   The Jet and JDS were very close in their performance -- air flow, nuisance dust left, ease of control.  The JDS, by virtue of having slightly lower air flow, didn't leave as much dust suspended in the air to later settle out when the machine was turned off.  I'll be you'll be fine with the Jet.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   Dennis, I did two JDS 750's rather than one bigger unit to create a mild race track flow around the shop that is basically two 12'x48' parking slots with the main beam and pipes holding up the ranch house above running down the center. One unit is 6' in front of the shop stove and moves the heat in the winter nicely to the other end and the other unit is 13' from the garage doors on the other side pushing clean air across the main shop space and fine dust towards the hot air rise near the stove to be sucked up by the first unit. You should only need one unit that picks up from the dusty-ist part of your shop and throws clean air across a corner to get a flow circulating. I found that the JDS  units are built better and they do offer promotional discounts at Woodcraft from time to time with coupons in the box for free replacement bag filters(it's nice to have one to use when you launder the other), they also discount their filter packs.

   Paddy, if $$'s tight, one can substitute a biggish box fan to help keep the air flow going.  Pretty cool, though, that you're able to run two filters.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   Has anyone heard of a Clean Air shop filter? there is one for sale at a shop that that just closed & I'm thinking of looking at it (it's only $75)

   Thanks

   Not a brand I recognize, and a poorly chosen name for a Google search <grin>.  I did find Clean-Air as a Felder brand, but don't see how there could be one of those priced at $75 even for scrap metal.  Here are the models.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   I went & looked at the Clean Air today, not much to it, looked like a box with a fan inside & a furnace filter at each end. I'm going to buy the Jet tomorrow.

    I did pick up a Delta 23-710 sharpening system from him, not seen to be the best system, but , he only wanted $25 for it, I didn't have one, so the one hour drive was worth it.

   Thanks for the help
