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.

I mean you wore a mask, but the dust will be all over you after so you can still ingest that once you take off the mask. Please answer. Super important for me to know.

@@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 Год назад

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!🤓

@VarikM Год назад

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.

@nunya3163 Год назад

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 Год назад

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 Год назад

@IzziedeD Год назад

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

@davidjames1063 Год назад

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 Год назад

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!

@rapa2464 3 года назад

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...

@ernestbeckley Год назад

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 Год назад

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 Год назад

@@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.

@renaissanceman8564 Год назад

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

And when it gets clogged to throw it away and cut a new .

@57WillysCJ 3 года назад

Nicely done. The circle piece added acts like a funnel to pull air through. It is the same application as the fan shroud on your vehicle. Without a shroud the fan pulls a column of air the size of the blade surface area.

Suggest s clarification - the shroud on exit side of fan keeps backflow from happening arond the perimeter.

And air flow increased per my fanflow measuring kit (duct blaster)

@williampolfus6975 2 года назад

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.

What if you made the box just slightly larger so you could have slid in the entire fan between slots without disassembling? Also, I’d buy a second fan and keep it so when the first one fails, you know all the parts from the second one are exactly the same.

Eric, I'm impressed, from 130 subs two years ago to almost 55K today. I guess I'll throw my hat into the ring too. I won't be able to use much of what you build as I will be living in a motorhome soon but I do like what you do and I pick up some good tips in almost every video. Keep the good stuff coming.

@johneken2056 Год назад

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.

@DeltaPhoenixHawk Год назад

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

@philgoulding5219 3 года назад

Another great video Eric! Thanks for a great idea. Even with 2 small cyclone/shop vac combos to keep saw dust down, too much still comes off into the air in my small shop. I am definitely going to build this. Keep up the great work! We’ll be watching!

Wow, thank you for taking the time to explain everything, so often the people making these projects forget most of us are total novices ...this looked something I'd try for my Caravan...subscribed and can't wait for yr next project

@chucklucas8747 Год назад

I just used two way tape an taped the filter to the back of my box fan the high density filter does work well this way

@robertlorimer843 Год назад

I've got a strong 30" shop fan I did this with just a couple of nights ago. I spray painted a shelf and since it's really cold here in Illinois right now, I had no good way of venting the garage without losing my heat. I put 1 filter on the front and one on the back, then turned the fan on high. Sat it a couple feet from my shelf. Worked way better than I when hoped it would. I could visually see it immediately pulling the overspray away from the shelf to the fan. There was virtually zero spray paint dust on my garage floor. Not bad for 2 filters from home depot for less than 5 bucks.

@Thomas-kl5mo Год назад

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

@theoakiemaker6599 4 года назад

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 4 года назад

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 4 года назад

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 😁

Thanks Chad! It’s the perfect way to keep that $20 HEPA filter on the front lasting longer!

@AlflixMcVideo Год назад

I like watching you work. I would personally simplify the idea to allow the fan to be exchanged as easily as the filters. That would save time and particulates during your build.

@michaelmartin8036 Год назад

Really hadn't thought much about how to get rid of all the dust, so this looks like a good way to help! FYI - I'm retired and just now getting my shop ready (aka 1/2 of the garage). I'm doing the "start off small and work my way up" mindset. You have to take baby steps before you can walk.

@fraserturner112 Год назад

I just bungee filters to whatever fan I have laying around and they work great at knocking the dust down when I do demo

@michealnelsonauthor Год назад

“Im not a geologist, so I’m baffled.” Great way to blow 2 jokes past the people… lol.

@daves2624 Год назад

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.

@llapmsp Год назад

Very nice idea and build. I think you said it best, something is better than nothing. Thanks for sharing

@jeffreyfroehle6414 Год назад

Just finished building this. Works great.

@limpeacock573 Год назад

One word of caution. If you do any spray finishes in the same shop space, don't use this rig as a way to vent fumes. The fan motor isn't rated for use with flammable materials. If it causes a fire, your insurance will not cover the damage. That was one of the first questions our insurance agent asked when we decided to go with a new policy for the shop. If you spray with water based finishes then you don't have a problem.

@tonymiller8152 Год назад

Yep tape works wonders to hold filters on the metal no need to waist wood

@dbworxmedia Год назад

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?

@Wastelandman7000 Год назад

Nice project! Would work for home filtering too. Well done.

@karencowan3458 Год назад

Awesome job guys !!!!!

@DonziGT230 Год назад

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

@jamesbrady2156 Год назад

When I first started I taped a filter to a box fan similar to the one you dismantled . I put a quality filter on the out going air and a cheep one on the intake. I still use it when I spray paint from a spray can to catch the overspray. Mine is much less work to "build" and probably works the same as yours. I have more expensive permanent units , as well now , but I still use my box fan for particular jobs.

@jbonkerz Год назад

I did the same thing recently as well. 20x20 pleated filter will stick to the back of that box fan by suction pressure (same one i use) while it is running.

@dfcbman 3 года назад

Thank you for this video. We all need a dust filter. I should have been using this years ago.

@SpencleyDesignCo 3 года назад

You’re welcome, Frank! It’s a simple solution, but it works pretty well for the price 😀

@GiSWiG Год назад

I have way more experience in building computers than wood working so here's a computer geek's take. The reason you need the round frame is for static pressure to force air more efficiently through the filter otherwise you will have air turbulence and less efficient filtration. Same principle when using liquid cooling in a PC; you want higher static pressure to blow through the radiator(s) to cool the liquid coolant. Of course, you see round frames for fans on ACs, car radiators, etc. I would recommend using a fan with a circular frame around it, use the circular frame inside the box, and fill in any gaps in the corners. You should also have at least one filter panel as close to the front of the fan as possible. The force of the air will keep it out of the fan blade. A panel too close to the back could suck in the filter and heat from the motor on the backside could be a fire hazard. Fan blade angle is also important. The greater the angle, the more air pressure. Really, a shop fan with a flat round metal frame would be perfect but they can cost more. Window/box fans are designed for breeze.

@georgewelker853 Год назад

The baffle prevents air from “recirculating around the blades” and pushes the air like a pump

@isaac198428 Год назад

A cool idea in theory but in reality, looks like the *fan would need to be set on HIGH* to work as expected since the *airflow is restricted* and the fan blades aren’t *designed* for such such a housing if you need efficiency especially at it’s *LOWest setting* . Like some people pointed out, the fan is supposed to be inside of the circular frame to help direct air not behind/before the fan. Sure the filters will trap some dirt but also increase the electricity bill due to the higher resistance. You had a good idea but they also build air conditioners/filtration fans for your specific purpose which are more efficient.

@delwoodkelp8590 Год назад

For those not operating a shop.... Just buy the box fan and a HEPA rated filter. No need to do anything except turn the fan on and place the filter on the intake side of the fan. Air pressure (vacuum) will keep the filter up against the fan when in use. Don't even need a clasp or screws OR EXPENSIVE Duct tape!!! Filters over 90% of the fan thru put. Use in California during fire season. Effortless to install... and super cheap. Will filter a room in no time as long as you don't leave windows open.

@michaelhenderson5098 Год назад

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

Geologist are the best when it comes to aerodynamics! Cool project, simple and effective. I suggest painting the mdf, otherwise it degrades quickly.

@SpencleyDesignCo 3 года назад

Thanks for checking out the video, Elias! Geologists are highly skilled! I thought about finishing the MDF, but I’ve had it up in the shop for over a year and it still looks brand new. Maybe I got some super special MDF??? 🤷‍♂️🤷‍♂️

@Paul-ou1rx Год назад

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 Год назад

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.

@flyingash 3 года назад

I use duck tape and a filter to the back of the box fan and have used my method for 2 decades with no issues

@SpencleyDesignCo 3 года назад

Yup, that’s definitely a great option! I was just looking to make something a little more polished.

@flyingash 3 года назад

@alonzoquinones8976 Год назад

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

@tlak 10 месяцев назад

Like others said, and mine is even simpler, take a 20x20 filter and let the fan suction hold it to the back of the fan. While it appears clean in the house the filter turns dirty after a month or so. And I don't know about the cirle thing if the box fan doesn't have it, but I could see that it would increase the pressure.

@jameslester4474 Год назад

Orrrrrr, You could do What I did, and not spend all day re-engineering a filter box, and just go to the local hardware store and buy the green filter material you use in your furnace that is large enough to cover the Box fan , put some Velcro on the box fan inlet side and the Green filter material will stick to it, allowing you to put the piece on and run the Fan on high. When you are done, pull the filter material off the velcro, take it outside blow it off with a leaf blower, or to get it real clean, wash it off with your garden hose. Then when done, tamp off the water let it dry and stick it back to the Velcro. I made two, so one would dry while I used the other. Very little dust in the air in my small single garage sized shop. And it all cost less than 30 dollars.

@tylergillmani5567 Год назад

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

@billiebowling7755 3 года назад

Good idea I have did this with my box fan simply by putting the filter on the back side of the fan with a couple pieces of duct tape

@SpencleyDesignCo 3 года назад

Yeah that would definitely work! I just wanted to make something that was a little more finished 😀

@Intarsia82 Год назад

I have 3 in my shop, just as you describe. I locate them next to my scroll saws and my sanding station. They are easily portable and take up little bench space. Simply remove the tape to replace filters.

@damikco1 Год назад

Nice! Personally i just duct tape a hepa filter to the rear of a box fan for a fast project to reduce dust.

@stephendawg1 Год назад

or… 4- 2”x 24” filters duct taped together into a partial box, close the back of the box with scrap paneling (plywood, thick cardboard, whatever is free) lay the box fan on the side opposite the paneling with the wind blowing away from the box, duct tape it to the filters. I’ve been using mine for over a year. I leave it on the floor, plywood side down, fan blowing up and some distance away from the source of my dust. I will occasionally shop vac my filters with a right angle brush attachment to pull off the worst of the dust and debris. Handy to move around my little shop, cheap and easy to store. Coarse dust/chips falls to the floor for sweeping, fine dust recirculates until the air current brings it around to the 4 filters and pulls it into the media. I’ll let it run for about an hour after a dusty project so it can scrub the air a little more.
