   Hi Dan,

   I have one I bought from Western Tool (Pioneer) and like it very much.  Since installing it overhead I have seen almost desidual NO DUST from power machines.

   I usually turn it on several minutes before running dust generating machinery to get the air flowing through the shop and leave it on for several minutes after I'm done with them.

   It also works great for cooling down the shop on hot days too but that may have more to do with my woodshop configuration.  It's on the second floor over the garage and tends to draw cool air up the stairwell.  In winter it also circulates the warm air from my heater too.

   All in all a most welcome addition to the woodshop.

   Regards,

   Bob @ Kidderville Acres

   A Woodworkers mind should be the sharpest tool in the shop!

   Dan,

   I thought I had posted a couple of links earlier but I cannot locate them right now.
   One of the other magazines ran a pretty good test and came up with an interesting finding. The put collector plates around the shop at various heights and locations. They measured the amount of dust captured and the amount of dust that settled out on all of the plates.
   One of the most effective was a standard box fan with a decent furnace filter attached and some shrouds to help control the air movement.
   Multi-speed did not contribute significantly to performance. Most units performed better at their lowest speed.

   Here are some links to some discussions on the subject review.

   Like every review you can find flaws, have more questions than answers, but at least you have more information than none.

   I find it interesting that the cost of the furnace elements comes into question. If the intent of any of these products iis to scrub the fine dust fromt he air, then I for one would want the dust in the fiters then in the trash. If the cost of srubbing the air is to high, then perhaps the primary dust collection at the machines should be upgraded to minimize the amount of dust getting into the air in the first place.

   It is all good information, getting the right solution for your application is always the tough part.

   Thanks for the replies. After more research, I've settled upon the JDS Air-Tech 750ER, which seems to have topped the reviews in the 3 magazines I was able to find. Dan

   DM, look for a sale or a promo at a woodcraft store, they run them from time to time. I picked up two at a discount with a cupon in each  JDS carton for a free bag filter set for each. They work great, good choice. Paddy

   All,

    

   It makes sense to me to use an air cleaner in the winter. The rest of the time I use fans to move air through the shop. I have a fan in one window blowing in and one blowing out. I have a garage door on one wall of my basement shop.   I built a rectangular box from 2x6 that has a screen on one side and has a fan screwed in the center. It fits under the door and allows clean air in. I think if you can change all the air in the shop 6 times an hour it has to be better than filtering when doing crazy- dusty operations. I believe this was figured out in the mining industry

   Of course you still need a dust collector and probably some sort of mask for some operations. I bought an airmate visor years ago when they were alot cheaper (Racall - now 3M) and I use that for beltsanding, sanding on the lathe etc.

   I am a pulmonologist. I have seen maybe 12 non-smokers with lung cancer in the last 15 years. About half were in woodworkers.
