This DIY shop dust filter is a must have! Is your woodworking space full of dust making it hard to breathe? Make this air filter and purifier for under $40! There's even a link down below for FREE PLANS!
We’ve been working in this garage space for a few months now and it’s awesome! The one problem we are having is that no matter how much we pay attention to connecting all of our tools to the shop vac, it still gets SUPER dusty in our shop! You might not notice it while you are working, but if you leave to go to the restroom and then come back, it’s really really bad and you’ll start coughing if you don’t have a respirator on. We needed a cheap way to clean and filter all the air in our shop to make it a lot easier to breathe.
We did a little research and found that we need to get an air filtration unit. No problem! Well, that was until we saw the price. Check these out to see what we mean
Unit 1 ~ $150
Unit 2 ~ $350
Unit 3 ~ $700
We simply can’t justify spending that money at this time, so we looked around and found some DIY versions that have super super good reviews. Now you can make one simply by duct taping a filter to a box fan, but we wanted something a little appealing to the eye!
We saw a video from Franklin Woodworks that was exactly what we wanted. Now we built directly from his plans, so these are NOT our original plans but we still wanted to make a video to help illustrate how we built it! Full credit for the plans and associate cutlist go to Franklin Woodworks.

@@slickcatricky7694 Rick, seriously, most use an air nozzle from compressor air line. However Worksafe in Canada, similar to OSHA in the US don’t like that because they feel you could blow an air bubble thru a cut in the skin and get into bloodline. Bad Carma. Considering options, I’d still use compressed air but use a regulator to reduce volume and a nozzle that sprays a wider pattern than a tight stream. Ask if you have more questions. I do FA in construction.

[@beeepizzle]

Pro tip… Just use some masking tape to tape the filters to both sides of the normal box fan, and just be sure that the airflow arrows are pointing in the right direction. That’s the easier version of this!🤓

Since the motor isn't meant to be a filter fan they burn out after a while a lot quicker than if it was just pushing air.

That seems like a lot of trouble with a weak fan motor. Taping filters to both sides will be rough on the little fan and it won’t last long but…..

[@VarikM]

Great idea and nice looking. Suggestion from the HVAC standpoint. Better to stack the filters both on the uptake side of the air flow with the cheap filter on top of the hepa. This does two things, of equal importance. One , having both filters on the inlet side keeps the fan motor and blades nice and clean. Two, a fan motor is happier pulling against negative pressure. Somewhat counterintuitively perhaps but it has to work harder when pushing against an obstruction, in this case the filter. I built mine with a salvaged squirrel cage fan (2000 cu ft/min). Paired this with a 2" pleated on top of a 4" 90% filter. Covered the fan on the outlet side with wire screen (1/4" squares). Noisy but moves a huge amount of air and will pull the dust out of your hand.

[@18deadmonkeys]

I just stack a Vortex extraction fan on an activated charcoal can filter wrapped in a fabric pre-filter. Gets rid of odors too. Bish bash bosh, Robert is your mother's brother.

[@ginoasci2876]

could you please show this on youtube and pin it here so we can see what you’re talking about…. thanks

[@nunya3163]

Good points. Also, if using a cheap box fan like this, you would want to put a shroud on it. Without the shroud to minimize recirculation, the fan will be inefficient.

[@latenttweet]

The filter distance to fan will effect more vs pull or push IMO due to stall area. You can look up stall curve on fan graphs if they have them. These cheap box fans barely have any flow and do not perform very well as a compressor type fan. All I do is bungee cord a 20x20 hepa to the back. I have like five like that. I pulled mold and meldew smell out of grandmas house with these. For the shop hepa doesn’t make sense it’s just a waste of money cause so many other contaminants in the air. But if you’re painting or burning plastic or something really smelly then maybe but a 20x20 hepa is like $15-30 range alone. I also use this setup a lot for paint booth exhaust. Keep in mind they are not explosion proof fans so maybe another reason to filter from the intake.

[@dougjones4987]

I did the same yrs ago

[@IzziedeD]

looks like a fun build. I did the short cut version, i bought the $15 lasko box fan, and a 20" home depot fpr10 (~merv 12) filter. popped the back off, slapped the filter on, replaced the back plastic over the filter & sunk 1 1/2" sheetmetal screws back into the original holes. works amazing around the house for clearing smoke after burning dinner, sucking up the particulate, dust and allergens on high pollen days or when dusting, folding towels or bedding

[@rickdaddy]

This is the correct way haha

[@davidjames1063]

Yet you didn't triple the size/ weight, nor did you reduce air flow 90% as this clown just did ! You got the same effect BRILLIANTLY.

[@blazetownsend8785]

Couple of things. First, good concept build and I don't want that lost in criticism. Second, you should install the fiberglass filters as a prefilter to the MERV rated filter. (It is not a HEPA Filter but will save your lungs none the less.) By using those cheaper filters first means that they remove the larger particles before it hits the higher rated MERV filter. This will allow for longer life of the higher rated MERV filter. The fan should be the last thing in the series as it will extend the life of the fan being at the back of the filtration. The Ring you made for the fan should be as close the the fan blades as you can afford or it will loose pressure to push air through, creating turbulent air instead of pull force. Turbulent air is great for cooling, but not forcing air through a filter. I hope this helps you or anyone else wanting to make these awesome filter boxes!

[@arleneportsmouth1263]

[@leemontgomery72]

Did the same thing but with tape. Works perfectly, this just seems like a waste of materials and time because the fan comes in its very own pre-made box.

[@joecontreras5068]

@@leemontgomery72 I was thinking the same thing. Did lumber suddenly get real cheap ? If you’re going to waste money on lumber then waste some more and hire a carpenter ...

[@ernestbeckley]

I did something very similar to this. A couple of lessons learned. First, the board with the circular opening. It is there to prevent leakage around the fan blade. The air will take the path of least resistance, which means the air is happy to circulate inside the box and never leave. Also, the blade needs to be inside the circular opening, for maximum effect. Second, don't both with MERV 7 or greater filters. The harder it is to push air through the filter, the less likely the air will move. The fan blades are pretty thin and weak. They are not designed to move air through a restrictive surface. If you add too much restriction, the blades will literally flatten out a bit, which reduces the airflow. That being said, this can work as long as you don't expect too much from it. I started by using masking tape to attach a 20x20 filter to the back of a box fan. Nothing fancy, but in a matter of two months, the filter was disgustingly dirty. Success! If you're looking for a quick and inelegant solution, just tape the filter to the back of the fan. Not only does this filter the air, it keeps the fan blades clean.

[@middleoftheinternet]

I agree, I would also be interested to know if the increased load on the fan could cause a significant increase in power consumption and potential cause the fan or wiring to short out. Probably not with enough airflow through it, but I would want to keep an eye on it especially if the environment heats up significantly in the summer.

[@MrCbell57]

@@middleoftheinternetthe fan restriction if any only causes the fan to pick up less air. These fans only live what air is available. So anything blocking the air flow will merely cause less air to be moved. As long as it gets enough air to keep the motor cool any variance will have some reduced effect. How much depends on the restriction.

Thanks for the filter box idea, square fans fit great in a window blowing out for a negative pressure when it’s not too cold outside. We crack open a window on the other side of the room just like in the kitchen when the fan is on over the stove and pull in some fresh. MDF has a lot of glue and fine dust when cutting = mask,,,mixing a bag of cement = mask,,, blowing off brakes or engine related= mask and glasses and gloves. Cement dust is a slow killer so in 20 to 30 years by the time you are in your 50s it effects your heart and lungs. The silicates are so small they never come out. Cutting tile or cement blocks or countertops. Shop vac if you can and up wind if outside with water. With the box, if the exhaust side is blowing up the dust from the floor the air quality might not be as clean as you hope for so putting it on a shelf in front of a window to exhaust outside might do the trick. I’ve done this for dry wall sanding and it makes the job easier for sure. My friends dad had a triple bypass from cement in his fifties and another friend has a bad heart from cement and construction dust doing Renovation. I hope you don’t mind my comments for your channel and thanks for the video

[@rapa2464]

Great DIY option! Regarding fan placement: Some rooms/environments have prevailing air current movements either due to thermal exchange patterns or poor construction(air leakage)/exterior air movement, etc. If you fill the room with smoke(think smudge stick, or a put a smoking friend inside) the movement of the smoke will indicate the native air movement(if there is any). Then you can place your fan to take advantage of prevailing currents(as opposed to working against them). If you have a convection or baseboard heater on one wall, the hot air will rise up that wall and across the ceiling before dropping down the opposing wall as it cools, taking fine particulate with it. If you place your filter fan in this path you may be able to increase it's air scrubbing capacity by taking advantage of the thermal/particualte flow. Follow the smoke pattern...

[@williampolfus6975]

I made a coupe of simple filters out of two different box fans a couple of years ago by just attaching a filter to them, but in both fans, a thermal overload protection in the fans caused them to shut down after running a while. The restricted airflow caused the fan motors to work harder and overheat. I had to add wood blocks as spacers between the fan and filter, so the fan could pull in some air around the filter and not have to work as hard and overheat and shut down. They worked okay after that, but weren't as efficient filtering the air.

[@SpencleyDesignCo]

I’ve had mine up and running for well over a year without any issues

[@rodc4334]

If you do that you are mostly just having air go around the filter - the air will mostly take the path of least resistance. Completely defeats the purpose. Maybe try another fan, I have done the with a couple of cheap fans over the years no problem.

I’m glad someone got my poor attempt at a joke! Thanks so much for stopping by and supporting my tiny channel and helping it grow! I really appreciate it!

[@JamesRichards]

@@SpencleyDesignCo Comedy gold. ;)

[@joeblough70]

Rocket scientist?

[@SpencleyDesignCo]

I think a rocket surgeon would be more helpful 😜

[@davearonow65]

That was funny.

[@josevelez5047]

Amazing idea! Blessings!

[@SpencleyDesignCo]

Glad you enjoyed the video, Jose!

[@billiebowling7755]

Looks good and has good seal

[@SpencleyDesignCo]

Thanks so much for checking out the video! I appreciate the support!

[@r.w.customworks8432]

Great build my man that’s gonna help a lot of people get a good affordable filter 🤙

[@SpencleyDesignCo]

Thanks for your support! We are shocked with how well it works

[@theoakiemaker6599]

Looks awesome. Gonna be making one soon. Any reason why you took the fan apart and not just out the fan inside the box?

[@SpencleyDesignCo]

Great question! I really just did it to minimize the weight as you would need extra material to make a slightly larger box. Definitely no harm done in leaving the fan intact

[@theoakiemaker6599]

Spencley Design Co. ok thanks for the answer. I desperately need one so I will probably be modifying your plans a little. Thanks again. Now to check out the rest of your videos 😁

[@SpencleyDesignCo]

I appreciate the support!!!!

[@theoakiemaker6599]

Spencley Design Co. no problem

[@daves2624]

In a busy wood shop that hepa filter would plug up in a few minutes and even the original plastic grate that you reinstalled to the box will also clog up... you need to 'exhaust' the dust.

[@DonziGT230]

The cheap, lightweight, compact, 5 minute version is the filters taped directly to the box fan.

[@fabulouspinkmk10]

Young man I just subscribed...the project was brilliant, but best of all you created something obtainable, that benefits most of the population that lives on a budget. We appreciate your way of thinking, because bottom line it works💪

[@SpencleyDesignCo]

I appreciate the support, Sandra! I’m glad to hear you enjoyed the project 😀

[@JAM-zb2vh]

That was nice I enjoyed it thank you and god bless you and all of your family.

[@SpencleyDesignCo]

Thank you very much! I appreciate you taking the time to support my channel!

[@shofarsogood7504]

Takes “ box fan” to a new literal level. I like this design.

[@michaelhenderson5098]

I made a simple frame for the filter for a 20 inch fan 12 years ago. :)

[@Paul-ou1rx]

I did something similar with the same box fan. I used large rubberbands and weather striping for a tight seal with filters front and back. Not a shop filter but it keeps dust & pollen down.

[@rodc4334]

I did that many years ago using elastic. Worked well. When the elastic got too old I just switched to wide blue painter's tape. Easy to remove, seals completely and easily.

[@darrenhileman1787]

Great video - great idea! Thank you for sharing.

[@allkindsofoutdooractivities]

Nice build!

[@leer3286]

I just taped a filter to the inlet of the fan 🤷🏼‍♂️. It worked well, cheap and easy.

[@OmniKingz]

Great job awesome bulid I love watching DIY projects god bless you brother

[@jerryrussell278]

Just found you, and dude this looks just as awesome as it does easy to build. Nice work and a great idea!

[@DeltaPhoenixHawk]

That's a smart way of doing it. I might have to try that.

[@jeffreyallen6091]

I made one. The box fan doesn't have enough static pressure to pass air thru a super cheap filter let alone a fancy hepa. Just hold a filter against it and you will understand.

[@andywyatt701]

NICE BUILD !!!!

[@SpencleyDesignCo]

Thank you, Andy! I truly appreciate you checking out the video. The channel is pretty small, but every single view makes a huge impact. I can’t thank you enough for your support

[@flyty2134]

❤ I really enjoy your videos you focus on common sense not spending a whole lot of money that’s a nice change I thank you for sharing this knowledge good job thanks again God bless you and yours

[@prayalways]

Loved it!!! Wow!!!!

[@alonzoquinones8976]

Man, this is a great idea. Gonna build one soon. ✅ Nice job big dawg

[@Thomas-kl5mo]

It looks Great and also looks as if you can clean it as well.

[@johneken2056]

20" square filters will attach directly to the fan box with bent aluminum tabs. Online filters all the way to MERV 13 in various thicknesses are available.

[@charleskiplinger9904]

Nice project. Why not throw four small casters on it so you can move it around the shop as needed.

[@curban0520]

Nice! If I build this , the only change i might make is combining the mdf shroud and frame and making it slide in like the filters.

[@SpencleyDesignCo]

That sounds like a really neat idea!

[@mythoughts1................1]

this video is a great tutorial for cleaner air in any room.

[@tylergillmani5567]

Will be making in the future. My pretty pink lungs deserve it.

[@automotivedyi1984]

Wonderful idea

[@chrisp.76]

Love your show! This my second time watching this one. Will be making one soon!

[@SpencleyDesignCo]

Thanks for watching! I truly appreciate the support!

[@bffentertainment7848]

Wow great job!

[@roomwithaview4195]

Thank you, that was really cool

[@dbworxmedia]

my understanding is that the fan motor is probably not made to handle the resistance that the filters will cause. will it not wear out sooner?

[@bprevost54]

Cool idea & instructions

[@SpencleyDesignCo]

Thanks for checking out the video!

[@lucasthesilliest]

now that is definitely a box fan if ive ever seen one

[@nealwright5630]

Great idea!

[@ToddAndelin]

good design!
