   As fas as I know JDS kind of set the standard a while back so maybe they are the best?  The word best is a strange one, especially in woodworking where everyone has the best!  :-)

   My significantly less expensive Pioneer from Western Tool Supply seems to work very well for me.  I did retrofit it with finer filter(s) though.  I like the remote too as the filter sits way up there on joists over the tablesaw.

   Regards,

   Bob @ Kidderville Acres

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

   I'm with Bob, the word "best" is a sticky one.  I have the JDS 750-ER.  I picked it up on craigslist.org for $125.00 (yea!).  But I would have gone with a Jet, Griz or Delta.  I love having a wireless remote, automatic shutoff and electrostatic filter.  Beyond that, you're pretty much good-to-go. 

   On a side note, my biggest "air quality improvement" was adding a overarm blade guard (with a dust port), to my table saw.

   Thanks,

   I just ordered the Grizzly.  The 1400 cfm and the 1 micron filter got my attention.

   Yea, I finally installed my JDS a few weeks ago.  The size was a little bit of a challenge... but everything went okay.  How big is your shop?

   One stall of a two stall garage which is about 25' x 30'.  I made the mistake of digging out a well a couple years ago and came down with a sinus infection that taught me how little dust it takes to ruin your day. Somewhere I got the instructions for placement of the air filter unit next to and about 1/3 the way down the longest wall and of course nearest to the greatest offenders like sanding stations.  Is that what  you did?

    I think the JDS site instructs for a ceiling mount with no obstructions - and allow for good airflow.  In truth, I just eyeballed a good spot and placed it there.  Your approach would be way too scientific for me... :0)

   steel city is running a special right now, $229.  ~1/3 the price of Delta, Jet, others.  I just got mine.  It seems too noisey, but that might be because i tried it out w/o reading the note saying remove the styrofoam spacers before using first time.

   interested in anyone elses thoughts on this unit.

   While every bit helps, be sure you understand what you are buying.
   These secondary filtration units filter to nominal 1 micron. They usually sit high in the shop.
   Most of the felt sock style (single stage, felt bag) collectors have some nebulous nominal efficiency rating of 1 micron.

   That should make us think that everything getting up to this filter is less than 1 micron.

   The best most of these ceiling air cleaners can deliver is 1 micron - 1 micron what. They don't say. A strip of flannel bed sheet taped over the intake will trap a certain percentage of 1 micron dust.

   Considering that the manufacturers of canister elements like Wynn and Farr offer efficiencies of 99.99% @ 0.5 micron, why can not someone selling an "air cleaner" provide the same.
   What is clean shop air?

   In time this air filter will build enough cake to actual make a difference, but it will take time. I think the main reason these devices work reasonably well, is the dual filters exposes the dust stream to changes in velocity and direction. Enough of the particles fall out of the main stream and start to build up in areas of lower turbulence.

   There is a study published in the October 2006 issue of Wood Magazine revealed that a standard box fan with a decent pleated filter taped to it ranked second to the JDS-750. 2 or 3 of these hanging from your ceiling might be more effective.

   Dust is an interesting beast. The stuff that settles to the floor makes a mess, the stuff that floats around the top of you shop for hours, that you cannot see, can quietly kill you.

   Always wear a P-100 or N-100 rated face mask regardless of how efficient you think your machines are.
