My shop is 24 X 34 X 12(high). That calculates out, with my fuzzy math, to be about 9300 cf.
I want to buy a good air filtration system. I have done some search on the differnt systems. I am thinking about Jet, JDS, and Powermatic. I think I need a system that filters 1000 cfm (=/-).
I would appreciate recommendations and comments on air filtration for a shop my size. Also, I am looking for the best face mask to use when I am cutting pressure treated wood.

CB, I am 24x48x8 and use two ER750's by JDS and I love em. They are set up to maintain a race track pattern of air flow to clean the air, move the heat from the shop stove about in the cold times and bring in the cool air from the garage doors in the warm times. Shop them for price, there are cheaper, slicker, bigger names out there but they are not better. Paddy
Thanks Paddy,
I knew JDS has been popular. That is why I put it in the mix. What about the filters. Are they good and are they easy to service?
CB, yes and yes. Some units come with free coupons for a spare bag filter. Paddy

scope out this...

It's a what a welder would refer to as a smoke eater. Typically they have furnace fans , a furnace filter type pre-filterand an electrostatic percipitator. (the al plates on mine weigh in at 35 lbs!!!)
I have one that I picked up surplus, and it not only circulates the air (and heat in a 12' ceiling shop, that makes a comfort difference too!)
I was worried at first that the electrostatic filter, which can sometimes spark, might pose a bit of an explosion/fire hazard, but after 3 years haven't had an issue with it.
they ain't cheap though, replacement cost for mine would be in the 4-5k$ range, but I can place the articulated arm directly over my assembly bench and sand to my hearts content.
Just anuther solution what ya don't see advertised in the WWing press...

I appreciate your reply. I ordered the JDS 750 last night. No turning back :-)
Coolbreeze, I think you'll be happy with the JDS. I've had one for several years, no complaints. What sold me on them was two different reviews, one especially where they did extensive testing on the efficiency of the units, how much dust did or didn't escape, and how well they ran when the filters were partially loaded. I'm sure things have changed since then, but I wouldn't be concerned about the JDS going backwards during that time, LOL.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
Thanks for your input. I've always respected your contributions.

CB, You could also make one for a fraction of the cost instead of buying one. Filtering air is not rocket science. An air filter is nothing more than a box with a fan on one end and 2 or 3 filters on the other end. The filters are usually a course one and a couple of fine ones. I use the high quality ones sold at Lowes for the fine ones (less than $10 each). I purchased an industrial fan from Grainger for about $70 and installed a pull switch but you could get fancy and install a timer so that it shuts off after a certain amt of time after you leave the shop. We are all woodworkers so making a box to fit the filters and fan should be a piece of cake. Caulk and screw some plywood together and paint it to make it really look nice. A door with weather stripping makes changing the filters a snap. Pocket the extra money for more tools!

Thanks, Frank
I already have the JDS coming. I never thought about making one and you are right. If we can't make one as you described, we need to be doing something else.
I will wait and see if my planned setup works.
I have a Jet air filter, but to me it is secondary to a dust collector that can catch as much at the source before it ever gets in the air. There are some processes that will put more dust in the air no matter what what you try and do to catch it at the source, belt sanding, ripping on a table saw, etc that to me is where the air filter really helps.
As for a face mask, since I do turning also and have a beard and glasses I use a Trend Airshield. But any TIGHT fitting mask is going to help.
Parrothead,
Thanks for your post. I have a 3M 6001 face mask I plan to ues when I am ripping. I have been buying medical masks at a surgical supply store. The are not very expensive but they are good. However, I want to do more than that mask. When I am ripping, especially treated wood, I am going to use the 3M 6001. and when I get through, I am going to take a coffee break to let the JDS clean the air.
Watch the beared! You may get wrepped up in your work :-)
