Building the Best & CHEAPEST Air Filtration for Your Shop

I like how you kept it real on the size… that thing was big 🤣 nice video man

Offset clips…thanks for the tip!👍

I built something like this about 15 years ago for a small shop I had at the time. Space was a premium. I made mine double duty. It was a dust collector and also a cooler for my compressed air. The contraption was mounted over the air compressor with the fan pointing down. The box had a plywood bottom with a hole in it for the fan. The sides and top were simple squares made of 2x2's rather than plywood. The bottom was 22" square and the 2x2 squares were set in about 3/4" from the edge. Everything was just screwed together with drywall screws. I just used some packing tape, filter to filter, to hold the filters in place. When the fan is running the vacuum created sucks the filters to the frame anyway so no real need to get fancy with the holders. The compressed air cooler was 50 feet of 1/2" soft copper wrapped into a coil and suspended inside the box from the top. Short hoses connected it to compressor and the water separator/filter. The air being pulled through the filters cooled the copper coils so water in the compressed air would condense and run down into the water separator. The air then blew down over the air compressor to help cool it as well.

Explaining how the dato stack works was really good. Nobody does that. Thanks

Loved your honesty and audibles! I can se where we tend to do things in a similar fashion. Sometimes my ideas are only in my head and changed as I go along. I have to do one these for my basement!!

Thanks for sharing. A good build that needs to be done in mine. Quick thought. Take the wire cover off the fan and turn 180 so the Lasko emblem is upright. If it bothers you. Keep up the great work. Subscribed!

The Corsi-Rosenthal box filters are amazing. They're better than anything you can buy, under $1k! Well done!!!

I’m making one of these for sure … thanks for sharing!

Speed control would be nice for the times you apply finishes. So as not to disturb dust in the shop. I use the remotes that are sold at HD to control the on/off of Christmas lights. Great job.

you have so much space! . with a bit of work that place could be awesome!

Great project!

I was wondering how to make a diy filter so I keep searching stuff like this and youtube recommend this video I can now figure out how to make one like this thank!

And there she blows (c) You've made my day - thank you!

Great project!! Tip: A sliding beam compass is easy to make from a few scraps of 3/4" pine or hardwood for large circle layouts. Cut the beams to the preferred length at 3/4"th x 1 1/2"w x your preferred length. Can make several beams different lengths for a range of diameters. The sliding pencil and center point holders can be made from small blocks of wood 1"w x 2" h x 3/4"th with one side of the 3/4" thickness relieved 1/8" from the bottom up 1 1/2" to create a ledge for the blocks to slide along the beam. Drill a close-fitting hole for the pencil (wrap with thin tape for a snug fit) thru one block, 5/16" in from the outer edge, centered on the 1"width. Next, drill a close hole, 1/2"dp for the center pin in the other block located on the center of the bottom (5/8" width) leg. and glue in a sharpened finish nail/brad with the head clipped off. A small, 2" 'c' clamp for ea. block is used to hold them to the beam.

Love the video, love the effort and passion. I do wonder, how heavy is that thing, and I'd rather the filters slide into the interior of the casing, removing the need for those external brackets and improving the aesthetics.

Great video! I'd like to shrink the box a bit. What are your thoughts on airflow if I use 12x20 filters on the sides and bottom (and 20x20 on the back). Would reduce volume by at least 33%.

I designed and built something similar except: I mounted the fan on top, there's a slide on the bottom for a 20x20, and around the sides are four 14x20 filters. Works great.

Nice vid. For those who want to be as safe as possible but also have somewhat limited funds this looks like a great option. Two things.. 1) you mentioned the shop temp was like low forties when you were making this. Can you feel the cold air circulating now as well when it’s running? 2) wonder if this would be just as effective on a rolling cart making accessing the filters easier and making it possible to direct above mentioned air. I don I don’t have heat in my work area either. Subbed. Thanks

Great video! I just purchased the plans for this from Shop Hacks and came to realize, there weren't any videos on how to build it! So I did a quick search on YT and found you. I am a new subscriber and am looking forward to digging in to some of your videos. As a follow up, how are you liking the filter? Is it reducing that fine dust that is constantly wanting to settle on everything in the shop? Also, how long do you run it for? TIA

Like it, but, think you need a cheap pre filter going into the fan.... to protect the fan motor......
