It’s time to get a smaller air cleaner. The field looks like the Jet 1000, the JDS 750, and Delta 50-875. All priced about the same, Delta seems to have some better specs, …so any advice from real world use? Thanks

My Delta has been fine for four years, and I'm on my 2nd bag filter (the expensive one). I made a wood frame on the inlet side to tightly hold two 12x24 pleated HVAC filters from HD to save th bag.

grover,
You can click onto Advanced Search here and find some info, but you'll porbably get more answers if you go to the Knots Forum. (check at the top of the screen) Most of those people spend lots of time in shops and are always messin' around with air cleaners. Just saw a thread there yesterday with a home built one.

edited to say: Once you get into Knots, try an advanced search in each of the sub-groups, "Tools", "Workshop", and "General".

Thanks Guys.....Read enough on the Knots side to settle on one and pick it up between jobs today. And tomorrow will do the 'aftermarket' intake filter idea....then I'm gonna raise some dust! Much appreciated...my first post ever--here, or anywhere
what did you settle on?
I went with the JDS AirTech **750**. Sort of had 3 factors: Comments in the Knots forum, including the info on the output specs, 2) Got the impression that Jds specializes/developed this field, and ...3) The company's in Columbia, South Carolina, not so far away--we're still pretty new to this part of the country, and the wife and I spent a pleasant long weekend in Columbia last winter.

there used to be an interesting article on Oneida air's site, the test showed "air cleaners" blew around more dust than they collected and what they collected would have settled on its on fast enough not to be a problem ..
why not vent out the back side if that is a problem. I just built a box air filter and installed a duct so I can vent it out of my garage if that seems to be a problem.
"why not vent out the back side..."In the winter, you don't want to waste all the heat, otherwise, setting up an intake and exhaust works fine (as long as the dust isn't affecting your neighbors).
I use a 3 hp Onieda dust collector - unit is in the garage outside of the shop for noise and filtered discharge is in the shop to hold on to the heated air. I also run a Jet 1000 with cheap pre-filters up on the ceiling. For sanders, I also run a shop vac. Its a constant battle! Norse
That's the ticket. I've also got the Onieda cyclone, in the adjoining storage building, with filtered return into the shop, and a Delta air cleaner. Sanders get hooked to my shop vac - makes the paper last longer, too.
Onieda did a nice job designing all the ductwork - I've never had a clog or problem.
I also use a pocket remote with two channels for the cyclone and cleaner.
I really hate the dust on everything!

You will have to excuse my ignorance.... but why would you be venting the dust...I thought the whole point of the filter system was for it to get filtered. so by the time it gets thru the unit its simply air that is vented. and also because while one side of the fan is sucking air in, the other side of the fan is pushing air, and that air needs someplace to go.
my impression was that the complaint was, that this exhausted air was a problem because it was blowing the dust already present in the shop around.
I totally disagree. I did a study in my last shop with Rick Wynn (of Wynn Environmental). We did real-time particle counts after cutting MDF. The dust is so fine it hangs in the air (for more than 30 minutes). I don't recall the actual numbers, but they were above OSHA limits. With my Jet 1000 on high, it cleared the air in like 8-10 minutes. MY shop was plenty dusty, and it didn't stir up more dust while on.
Oneida just tries to sell more cyclones!
My opinion - use both a dust collector and an air cleaner if you have the means.
But if that dust hangs in the air for 30 minutes, you are breathing it for that long unless you use a good dust mask. I was all set to buy one when I read that on a dust collector website...Bill Pentz. This guy did tons of research and after that I got the dust collector instead.
Just more info...I am not an expert by any means. Since using my dust collector and a high dollar mask, my asthma problems went way down. I keep one mask in my van and one in my workshop.

I think you may have missed what I was trying to say - WITHOUT the air cleaner, the dust stayed in the air for 30+ minutes at very bad (high) concentrations as per the particle counter. After the cut, we turned the air cleaner on, the particle count dropped off to nearly undetectable within 8 minutes. Leaving the cleaner on during the cutting kept the level from spiking very much at all.
But, you're free to beleive Pentz all you want! :-) Like I said, having both (plus a good respirator for really nasty dust) is probably your best bet.
After I posted this, I wondered if that wasn't what you were saying...30 minutes in the air w/o the aircleaner. After 15 hours though, I was too tired to look and edit.
Years ago FWW had an article written about dust collection, and one of the guys they interviewed talked about a device in his shop that use some kind of electric field and all he had to do was push a button and all the dust dropped to the floor...never saw one for sale though. I wondered about that.
But with the collector, air cleaner and dust mask for the nasty stuff, I think you have all bases covered.
