    Nice use of combining filtration and shop tool. Just curious where do you park cars?



  2. William Joseph on February 28, 2022 at 10:59 pm

    Now I know what to do with that extra blower motor. Thanks

    Nice build! I’m gathering info to build this kind of device. I’m worried that the air being blown from the box will generate turbulence and make dust fly around even more… How is your experience up to now on this?



  4. Byrkster on February 28, 2022 at 11:01 pm

    So its been a while, is there an updated video? How is it working?



  5. joeychgo on February 28, 2022 at 11:02 pm

    How about an update?



  6. Robert on February 28, 2022 at 11:10 pm

    Smart design!! 👍Very clean, economical and efficient. Thanks for sharing.

    I like how you used a square to keep your jigsaw straight.



  8. Leon Zantvoort on February 28, 2022 at 11:16 pm

    Nice thing you’re doing there. Good for your health too. But watch out. Wood that you can use is not scrap. It’s just expensive material you don’t just throw it away.

    I’m going to build one of these! I have a small shop that needs more filtration and another flat area to put my new benchtop planer! Great idea Subbed!



  10. Jeffrey Wang on February 28, 2022 at 11:18 pm

    Simple and proper design.



  11. im rwoz on February 28, 2022 at 11:18 pm

    Thanks, now all I need is a blower motor !



  12. Joshua Stewart on February 28, 2022 at 11:19 pm

    If I can’t find a blower, would one of those air movers (like mold removal teams use) work for this? Having a hard time finding a fan for less than retail…



  13. Aztec Arts on February 28, 2022 at 11:21 pm

    What’s the gap between the inside sides and the fan / casing ? Is this "restriction" or it does not affect the fans since you have filters that offer wind / air "resistance"



  14. BigPhat HairyDheel on February 28, 2022 at 11:22 pm

    OH FFS GET TO THE POINT



  15. Vine Len on February 28, 2022 at 11:22 pm

    Your need to change your draw pulls to spoked Bs. You’ll find they will improve the look and atmosphere in the shop. You’ll be much happier. Go B’s!



  16. HRTsAFyre on February 28, 2022 at 11:24 pm

    Very clever and useful. Nice build.



  17. Chau083 on February 28, 2022 at 11:24 pm

    @jaybates how has this design preformed over the past few years? Are you still using it? Is it effective? Would you make any changes? I have an old rigid cieling mount that doesn’t work that well and filters are discontinued and its begging to be replaced.



  18. ilive4livemusic on February 28, 2022 at 11:24 pm

    Super helpful. I found this through a comment on Izzy Swan’s video on box fan vs air filtration. This gives me a great idea on how to turn dead space from a shop cart into usable air filtration and shop cart.



  19. Ronald Evans on February 28, 2022 at 11:24 pm

    Yo you need to patent that man that is so neat thanks for sharing. I want to make me a air purifier out of a box fan and some filters like you did thanks again keep on creating….



  20. Mark Koons on February 28, 2022 at 11:25 pm

    You did well to design around a blower that can be regulated down from its maximum capacity. For a larger shop I built 2 units using attic vent fans. They’re unbearably noisy but, boy, do they filter some air in a hurry. They were hung from the ceiling when I had a mezzanine for access but now I’d like to use them as roll-arounds. Overkill. Be advised, fellow woodworkers.



  21. Wisconsin Bush on February 28, 2022 at 11:27 pm

    Since you bought 6 filters from Amazon, 4 filters is over kill and you have 2 extra filters. You could eliminate the front filter and make that a solid plywood piece that way you have 3 extra filters for next filter change.



  22. Tristan Wegner on February 28, 2022 at 11:28 pm

    5:50 that is a cool effect with you commenting on yourself doing the work.



  23. George Liang on February 28, 2022 at 11:28 pm

    you do not need Merv 13, filter will be loaded up too quick. Merv 7or 8 plated filter is good enough. Shop is not hospital. Thank you for the design!



  24. Claude Bieniek on February 28, 2022 at 11:29 pm

    This is the 2nd video I’ve seen for air filtration with dewalt planer on top. Neither one has chip collection, what’s up with that?



  25. john meye on February 28, 2022 at 11:30 pm

    Beautiful, great idea, think I’ll build me one!



  26. thegreatmoa on February 28, 2022 at 11:31 pm

    Love the effect at 6:00. Nicely done! You’re lucky to be able to have a shop assistant that’s (hopefully) always on the same page 😁



  27. JeyJey on February 28, 2022 at 11:31 pm

    Nice camera trick. The first video I’ve seen do it.



  28. PuJo-JoJo on February 28, 2022 at 11:33 pm

    Jay, do you happen to know the CFM rating on the unit your unit?



  29. Steve Mid TN T-Trak / Chicago & SouthEastern MRR on February 28, 2022 at 11:36 pm

    Currently I only have a 1 box fan with a Filter. However in the future I will build a cart version.



  30. TubeHammel on February 28, 2022 at 11:41 pm

    Got a free blower motor from my furnace installer and am ready to go! Thanks for this video, Jay!



  31. William Scavone on February 28, 2022 at 11:43 pm

    Nice design. I just scavenged one of 3 blowers that I have available and I love this design. My intent is to be able to run some ductwork from it so I can exhaust the air out the garage window. Do you have any thoughts on how to avoid sucking all the cold air in from outside and exhausting all my "warm" air from inside the shop? I live in New England and with winter coming I’d love to be able to run this in the winter. My shop is uninsulated and unheated, so I’m not losing $ but will be losing some of the benefit of having the garage door closed.



  32. Saul Castillo on February 28, 2022 at 11:43 pm

    💪👌👏



  33. SuperZmeister on February 28, 2022 at 11:43 pm

    I now have a plan for my own filter system, thanks to you for explaining the details.



  34. Pete C on February 28, 2022 at 11:44 pm

    Mobile air filtration – while a cool idea – drawing all the shop air to where you are is counter-intuitive. You’re pulling all the dust near to where you’re working. Mine is planned for being on the wall nearby the shop dust collector system. Any leaks are drawn away from me and clean(er) air comes my way.



  35. Dale Boyer on February 28, 2022 at 11:44 pm

    Now that you’ve had this for a couple of years, I’m wondering what your feelings are about it. Are you happy with it? What would you change about it? How do you feel about just one speed? Does it do the job you expected it to do, or was it a waste of time? The reason I ask is that I just replaced the HVAC in my house and so I now have a (4-speed) blower sitting unused, in my garage. I’m planning to make one of these (thank you for the inspiration), but wanted to touch base with you about it first. Thanks!



  36. lintelle on February 28, 2022 at 11:46 pm

    lemme guess: you live in Cincinnati??



  37. Robert Rynes on February 28, 2022 at 11:46 pm

    Great video!! Any idea as to the CFMs of the fan when wired for the low speed?



  38. Piperalpha81 on February 28, 2022 at 11:46 pm

    Great idea. I’m going to build one



  39. Aztec Airbrush on February 28, 2022 at 11:50 pm

    Just got one of these … (larger) with an external, top-mount / belt-driven version …
    I tested it, in open-air, and after 5 minutes or so, it stopped. I was sure i burnt the motor, BUT, after reading the data, it says "thermally protected" soooooooo my thought was that wen it reaches a certain temperature, it switches off (logic)

    10 minutes later, i heard a small "click" in the motor …. so i decided to re-plug it and start it again … as expected, it ran ok, but i stopped it manually.

    Question : If i build an enclosure (box) for mine with reduced intake area, will that PREVENT it from stopping randomly, as i would believe, the motor would be working less hard with more restriction applied to the wheel inside ?

    Sorry for the long "question".



  40. Bill of all Trades on February 28, 2022 at 11:50 pm

    That’s awesome, great design!



  41. Eric Newport on February 28, 2022 at 11:50 pm

    Looking to build this. I like the design.

    Question: does anyone think sitting the fan on it’s side, so the intake faces up, would hurt the fan. I would support the case of the fan so the motor didn’t sit directly on the base. Thoughts?



  42. Trevor M. on February 28, 2022 at 11:50 pm

    Great build.



  43. Bryan Kopesky on February 28, 2022 at 11:53 pm

    Been thinking about a better fan than a 20" box fan. Thinking I can find a used furnace fan easily and build one of these beauties! Thank you!



  44. Leonard Austin on February 28, 2022 at 11:54 pm

    Built something similar, ThANK YOU for inspiring!!!



  45. Charlie Odom on February 28, 2022 at 11:54 pm

    This is super cool! My only concern is something poking right through the filter. I would have to put some type of guard over the filter to keep me from sending a piece of lumber right into the motor!



  46. Enrique gudiño on February 28, 2022 at 11:54 pm

    all dust is cathcjed in filters,good idea



  47. K C on February 28, 2022 at 11:55 pm

    Hi, The DIY box air filter is fine with me. Could you help me get 1 unit and a few extra filters to fight dusts and other allergens? I am gonna pay for the costs and shipping. Can’t shop online at the moment. Thanks for your help



  48. MadPedalBoards on February 28, 2022 at 11:56 pm

    If you find the motor is getting overly hot, INCREASE restriction. These need a certain amount of static pressure to work efficiently. Nice work.



  49. Rex Cowan on February 28, 2022 at 11:56 pm

    Your video was exactly what I needed. I was overthinking how I was going to make my air cleaner. Thanks for a well done article.



  50. Hasmukh V Patel on February 28, 2022 at 11:58 pm

    what size did you cut from 2×4 leg ? is 1"x"1 ????
