   I would have to check my numbers at home, but I have a filter system from jet, and as far as I know the filter is not a proprietary design.

   I thought it was something like a 12X24X1 IIRC. Will check when I get home.

   Perhaps I read an old review, (I hope so.), but the guy said the filters were 11-1/2", not really 12".

   Any info would be appreciated.

   OK, I guess I will have to pull out a tape measure for that, as they Say they are 12" on the outside of the filter, in the same place a normal filter would give the size.

   It may not hold true today, but at one time the JDS was demonstrably more effective than the Jet or the Delta.  I have a JDS and could only be happier if the pre-filter was exactly the size of a store-bought filter. As it is, I can scrunch a little at the corners and get one to fit, no harm done.  The bag filter is the critical component.

   I have a Jet filter. The inner filter is 7 years old and running fine.  I just gently shake it outside in a windy day. The outer filter can be the issue. I bought a washable filter from Jet, and clean it about once a month. That filter is now about 3 years old and works just fine as well.  The non-washable filter that came with the unit worked for about a year with periodic cleaning.  This is based on about 20 hrs a week of use in a partime shop.

   Hi

   I have both units and they do a great job filtering the air.  The JDS inner filter is more substantial than the Jet but it comes at a price; the JDS inner filter is a little more challenging to clean and easier to damage.  You won’t go wrong with either one though, as long as you clean them regularly.

   Ok took a tape to the filter and it is in fact 11.5" (says 12) but while I have not looked into this, my HVAC guy here says that filters are under the size listed so that would not be odd. Says it is something about the size listed being the space they fit in. not the size of the filter itself. I have not looked yet but I will do so.

   Hey there Northhouguy. I have been looking myself and have settled on
   the Powermatic 1200.

   After reading about all the brands in the $300-500 and reading reviews I was happy with my decision and was able to get the PM for $399 and it has a $50 rebate.

   Best

   I have the Jet and use 3M 12x24 furnace filters and they fit just fine. You have to push in the corner a little, but that is not an issue. That size is a little odd to find locally so I ordered a case (12) from my local Ace Hdw. for about $3 each and I will always have one when I need to change. Jet and Powermatic are owned by the same company WMH Toolgroup so they probably have a lot of similarities except for price. JDS is good stuff, but I doubt if their unit is $137 better then the Jet. When I bought mine it was $199 (quite a while back) so I can't see it being that much better. That unit has been around a long time.

   I am not looking for one, I am not the OP. I was just answering the question about the size of the Jet filters.

   Hey Fred,

     I don't know if your stuck on buying a commercial filter system but I recently built my own system using the blower out of my old house heater.  It's actually a downdraft sanding table that also functions as an outfeed table, assembly table/work bench, and with good fliters installed it does a great job as an air fliter.  I used scrap material for the majority of the project.  The only material I had to buy was the MDF for the top, 2x4's for the edges, casters, and a bathroom exhaust fan timer.  I built it to use the same size filters that I use in my house to cut down on the confusion.  The fliters are cheap and easy to find.  It has made my shop 10 times more functional and cleaner.  I leave it running while I'm working and at the end of the day I set the timer, close up shop and it turns itself off.  Hope that helps.

   Brad

    Fred,

    I've had the JDS in my small (10x17) basement shop for a year and a half or so, my qualitative rating of it is "very good". Of course, I do not have a Jet to compare it against in terms of performance, but suspect that folks out there with experience on both are few and far between.

    I bought the JDS since it was top rated in a mag review a few years ago (FWW?).

    I also bought a Dylos air quality meter so I could get some actual data. The JDS can take the particle count in my shop from 10,000+ down to under 100 in a matter of a few minutes. I like to see it under 100, if it's over 100 I put on a respirator.

    The JDS can take the count down further to 0 or 1 in about 20 minutes (if I leave the room so as not to kick up more dust). Lastly, if I turn the JDS on before starting to make dust, it'll prevent the particle count from going so high, but I don't have any quantifiable data on that for you, just an observation.

    If I was starting woodworking today the first tool I would buy would be the JDS.

    Plus I believe it is made in the USA rather than China/Taiwan, though I am not 100% sure of that, you might want to check further if that is of interest to you.
