I’m looking for some advice from my fellow LJs on air cleaners. I’m looking at buying or making an air cleaner for my shop. I’m tired of having sawdust all over my tools after I work. I do wood working as a hobby. I was looking at buying a small ceiling mount air cleaner or building one of the box fan/furnace filter ones.

The biggest deciding factor for me is the effectiveness of the box fan ones. Are they comparable in performance? I’d buy a timered remote if I built one. My shop is a single car garage right now but I plan to build a new, BIGGER shop in the next 5 years or so. Does anyone have any experience with both? Thanks in advance!

I’ve got the Shop Fox W1830 for my 2-car garage shop and it works great. They make a more robust version (SHOP FOX W169) also.

Both have three speeds and have built-in timers as well, so that’ll save you some effort. For $179 bucks, it’d be hard to build one for much less and they do go on sale from time to time. I think I paid $139 for mine.

Look at the Wen air cleaner. It’s a great little unit, for about 1/2 the price of a Jet or Delta. You can grab it off Amazon. It’s also where to buy the pre-filters, too. Has a nifty remote controls 3 different fan settings along with a timer. I just found one for a little over 100 bucks….can’t go wrong, there.

It’s not going to clean up your shop, entirely…..but it will help with the fine dust, which is the dangerous stuff.

+1 for the WEN. Had mine given as a gift couple years ago. Works great. Do stock up on filters so you have them when you need them.

Here it is mounted in shop.

I built my own DIY air filtration unit, using an old squirrel cage blower from on old furnace. It works great and catches all the tiny dust that my DC misses..

Yup, another recommendation for the WEN (pretty much the same as the Grizzly and ShopFox versions, with different paint). I have the Grizzly, but got mine when it was on sale for $125. It’s surprisingly quiet, works quite nicely, and the pre-filters can be blown out several times with a compressor (using low PSI). I’ve examined my secondary/washable filter several times, and have yet to need to clean it out.

I was just watching a bunch of Youtube videos of builds on this subject. Matthias Wandel seems to be the one to review and copy/modify his designs. But he did build the impeller and housings as well. I do have an old motor from an electric lawn mower that I have been trying to decide what to build with and this seemed like it might be the project.

If anyone has tried this and has any good advice from their attempt I am all ears.

cheers

This EJWOX 3 Speed Remote Controlled Air Filtration System 400 CFM looks like the same unit as the WEN for less money.

Yes try the Wen! They have them reconditioned on their website for $100 and free shipping. I just got mine the other day and it’s very nice.

I’m for making it. Here’s mine.

http://lumberjocks.com/projects/15760

I have 2 air cleaners in my basement. 1 at the ceiling and this one down low. This one now as a radial arm saw on it.

I also use a box fan with a furnace filter taped on when I’m making a lot of dust.

If you can source a fan from an old furnace, building one is incredibly cheap and they are effective. I like them (shop built) better than the commercial units. I left my last shop built in the shop building some years ago, but I’ve now got another furnace blower and intend to build the next one. The shop in between had a commercial unit…I left that behind as well…no regrets.

Store bought aren’t very expensive, so I wouldn’t make one unless you would enjoy making it as a project.

One point besides the price to consider when comparing the commercial units (disclaimer: I used a home brew set up for years and now have the Jet). You cannot filter air unless you move the air. The lowest speed on the Jet and similar units moves more CFM of air than the highest speed on the Wen. Comments about the Wen being quiet and the secondary filter not needing cleaning give me some concerns that it is really not doing the job very well. I vac off the primary filter on my Jet occasionally, and check the main filter bags. The latter have not required a thorough cleaning yet, but the bags are clearly discolored with the fine dust they have captured.

I would be inclined to agree with you, K-man….but the size of the shop is relevant here, too. Also how much it’s being used. He’s a hobbyist, with a one-car garage. The Jet is kind of overkill.

But, I would certainly go with a commercial model, anyday over the home-brew version. I’d use the furnace motor and make a good sanding table.

I just finished this one, squirrel cage with 4 speed motor,12 intake filters and 1 out.
I have only had it going for a couple of weeks and used it maybe 4 times and the filters are noticably capturing dust.
It moves tons of air and seems to work well.
I have nothing against commercial ones other than the price of the filters.

My DIY (in post #4), has two speeds and moves air at 1,100CFM and 1,320CFM (measured). And that is through a 4-stack of filters (FPR 2, 5, 7, & 10). More than enough to create a circulation of air around my 24’x30’ shop. Nothing wrong with commercial units other than the price/performance ratio, IMO.
