Topic tags/keywords: question air filter

I’ve been looking for a small, basic air filter for my small shop (9’x13’). The popular Jet model seems a bit big and would be overkill for my needs. The only smaller models, however, appear to all be discontinued. There was the one through Lee Valley (,42401&ap=1) and the Ridgid model (, but neither of these are available. Does anyone have any other recommendations or know of vendors still selling these products?

What about the Shop Fox W1746? Amazon has it right now for $100.00 with free super saver shipping…

Or the Shop Vac 1030000 for $119.99 (Filtration on that one is somewhat poor at 5 microns, but the Shop Vac HEPA replacement filter might work with it…).

If you are willing to bump up size a little bit, and move a LOT more air, maybe the Grizzly G5955 would be a good fit for you.

I am uncertain about the models you linked, but I fear they may have coarse filtration as well…

Thanks for the links db. It seems you’re right about the shop vac, +5 micron filtration is not ideal and I’ve had a hard time finding any mention of compatible HEPA filters. The Grizzly looks good, but it’s size is a bit big (though I know I would appreciate it later when I get a bigger shop). I will be giving the Shop Fox some serious thought. Thanks again.

Dan, here is a link to a shop fox model that grizzly sells that is close to what you are looking for.

Richard, that’s the same Shop Fox filter I linked to that Amazon is selling for $100.00 flat with free shipping… Honestly, it’s a good deal. No idea if the filter is all that, but for $100.00, in a tiny shop it might be worth it…

Dan, after looking into your workshop posting again, I see your problem. Yeah, I wouldn’t worry about a big unit either! You may end up having to clean out or replace the HEPA filter in that little Shop Fox, but it would be worth it.

I have to ask. I don’t see even a shop vac in your workshop. You REALLY ought to collect the dust at the point is it made. Ambient filters are only made to help catch what dust collection misses… At a minimum, a shop vac with some sort of separator and a HEPA filter is needed. I don’t think you have the space for a full blown Dust Collector in there through…

I started out with, and it worked pretty well… A Ridgid 12 gallon shop vac, that pulled through a 20 gallon Thien Cyclone trash can separator, that was on a rolling “Stacker” that I built from scrap. It worked great on everything except the lathe, and planer…

I wouldn’t use a shop vac. It’s super noisy and when you turn it on and off it can drive other people living with you insane.

Since you’re in a 2 bedroom apartment with shop shared with living space I think the air filter is the top priority.You may sweep more if you don’t have shop vac or DC, but first and foremost the fine particles must be kept from drifting into your living area.

I have the Ridgid one you mentioned, and it’s not that impressive. I feel only a small weak draft from the end. Compared to my full size delta AF, even on the lowest setting, it’s night and day.

I would much rather have a smaller proper air filtration unit

I doubt my Ridgid jobsite filter is much smaller than the above Grizzley. Pictures on website make the Ridgid look a briefcase size, but it’s pretty huge. I can measure mine if you want to find out for sure.

As for DC the small Rockler 600CFM one may work for you.

Thanks for the input all. I think I will be going with the Shop Fox for now, since the price is right and I really don’t have space for the ceiling unit. If I upgrade down the line, I’m sure I will still have a use for it for fine sanding at a workbench and such. I’m sure it will beat my current setup of a box fan in the window, or worse, a furnace filter in the winter.

db – I appreciate your concerns. I do have a ridgid shop vac with a HEPA filter that I use on most tools (under the chop saw in pics 1&2). It fills up quick but I’m pretty good about cleaning it often. I look forward to the day I can get a dust collector with dedicated piping to all tools. I also don’t have a jointer or planer, so that keeps the mess down (though sometimes I find myself knee-deep in plane shavings). I have also been looking at the separators that go on 5-gallon buckets, as I just freed up some space next to the vacuum. My last line of defense is also a half-mask with n100 filters for when I’m sanding, cutting/routing MDF, etc.

RedShirt – Fortunately for me, I only share my apt. with my girlfriend, and she’s willing to overlook the noise and dimmed lights because most of my projects go to her or our apt. We also dont share any floors or walls with neighbors, so I have yet to get any complaints. Plus, the city is just a loud place to begin with.
