this might be one of my favourite videos of all time. straight to the point, great idea, great execution, accessible, cheap and most importantly: the angry way you do the most regular tasks. made my day, will definitely build for my shop!
@@davidcurtis5398 it is only logical to pull air through the filter and not push air through the filter.Imagine when the filter is full of dust but the fan continues to blow air in the filter,isn't the fan going to churn the dust that was collected in the filter ,back into the surroundings again ?
I just completed the purchase and assembly of the air filter and fan. The casters were mounted to the base using your suggestion. I used 80mm magnets I bought from Harbor Freight to attach them to the metal bottom. Works great! Thank you!
This looks perfect, I’m a self employed renovation/finish carpenter. This will be a great addition to keeping my customers home nearly dust free. I’ll still set up a cut room with zip poles and floor protection but having one or two of these going will really set their minds at ease. Thanks for sharing!
@@coffeeman9475 How will it do that? The filter he is using is just short of a HEPA filter. I would think that it would capture almost all of the dust that hits it.
The fan must reverse the direction of rotation in order to do that. You know it doesn't do it by itself. I'll be happy to waste my time on this project.
Super idea. I like this far more than the 4 filter and box fan rig I put together. Only thing I would have done different is just self tap screw the wheels to the bottom of the filter and maybe a dab of silicone on the inside.
Great job! Next would be to add a "General, Dyer, or Amazon Chinese "u-tube" water column pressure drop monitor to tell when to change the filter. Not the diy one bc simplicity is key and those dry out.... great for home furnace viewers too as theirs hardly any concise videos on them and NONE with qnd accurate PM1 METER!! Kudos for getting quality and such a simple and efficient build!
Awesome design! A minor correction: with respect to the Dylos DC1100 Pro, that number on the left is actually particles greater than .5 microns. (The number on the right is particles greater than 2.5 microns. There is some overlap between the left and right measurement particle sizes, yes).
Saw almost this exact set up by Jet at my local Woodcraft store, (JET AFS-850), for $699 and it only pushes 850CMF. I will definitely be ordering your solution for my shop. Great video BTW, I will be subscribing and watching your content. Thank you!
I think the fan blade on the fan in this video is NOT meant for sucking,but blowing. A fan blade that sucks in has to be extremely close to the frame or very little suction happens. This suction fan would be many times the cost of a blower, I estimate.
Thanks Cameron - yes I considered it. I went this way for a couple of reasons, 1. I wanted the dust on the inside rather than the outside to avoid accidentally bumping the filter when it’s off and knocking off all the dust. 2. I wanted to avoid a large blast of air directed into the ceiling. 3. The fan controls would then be inside the filter requiring a remote control start (like a dust collector remote)
Hi Matt, Thank you for posting this extremely helpful and innovative video. I have a question. Do you find that particulates eccesively accumulate and the inside bottom of the filter, limiting its effectiveness, or perhaps requiring frequent cleaning? Would it be useful to cut out a hole on the bottom of the filter and add a bucket underneath via a Gamma Seal Lid? Portability can still be achieved by resting the bottom outer lip of the filter on a small wooden frame, with a circle cut to accommodate the suspended bucket, and with wheels on the bottom. The bucket would just be suspended inside the frame and over the wood base. If it had a little clear plastic window, one could see the collection amount and be prompted to cleaning. I ordered the Wynn filter you suggested along with the CAT fan. I now just have to order the Gamma Seal Lid and bucket. I think this entire set up is outstanding, and should be in every shop. In addition to this, I will still of course have my table saw, band saw, and mitre saw attached to my powerful shop vacs for the larger particulates. Thanks again.
Since the fan is so easy to detach, I just take the filter outside (with the fan off) and blow it out with a leaf blower every few weeks - it’s very simple to clean. From what I’ve seen, most of the dust goes into the filter rather than settling at the bottom, so I’m not sure a gamma seal would do much (maybe?). I have a gamma seal bucket on my actual dust collector filter and it works great 👍🏻
I have a similar setup but my fan is pulling air through the filter. This keeps the fan cleaner as the air that pass through the fan has already gone through the filter.
@@mmcc_woodshop6288 i have a dual hose portable AC unit...im wondering if i can make a filter using merv 13 paper and foam to put inside the intake hose? ..im in an area effected by wildfires. Do you think il strain the AC motor too much? Thanks for your honest opinion.
It depends on how often it’s used. These filters are meant to go on dust collectors - they would see way more dust from an actual collector than from this setup
So, 6 months in, how would you say its working out? Noticeably cleaner air in your shop? Thanks for posting this video. Still on the fence between building a square filter box vs just strapping a fan to one of these pleated cylinder filters.
I’m happy with it thus far 👍🏻 I usually only have it on when I’m doing something that creates dust I can’t control - router, sander, router plane, etc. While it doesn’t circulate the entire room, I think it does a great job at localized filtration
The filters can be cleaned and don’t need to be replaced. It depends on how much you use it but it’s probably reasonable to clean it once a month or so
Forgot to mention, my local hardware store sells disposable MERV 12 square filters for $34 - each. This makes the cost of your idea seem more sensible when you consider the reusability / cleanability feature and that you get HEPA quality @ MERV 15.
I love the simplicity of this but there is a method that everyone overlooks and is even simpler. As you have a dust collector already with the filter, just add a speed controller to it and run it at a lower speed when not in use. Also for cleaning the filter, just blow the outside with air while still attached to the bag beneath, allow to settle and no more removal of it required. 😂😂😂
I’m not sure if they’ll actually need replaced. I clean the filter out with a leaf blower outside every 2-3ish weeks and they seem to function as good as new. My actual dust collector filter gets WAY more dust in it passing from the cyclone - I clean it the same way and have had no issues whatsoever
@@mmcc_woodshop6288 If that's the case, this is a clear winner over the furnace filters. With the exception that the direction of airflow cannot be reversed and the fan placed so as to blow the air upwards.
I just built your filtration system, works great but reading several comments about reversing the air flow I would like to try to do that. One big problem, if I turn the fan over there is no way to access the on/off speed switch. does anybody have an answer to this? ( I guess I could turn to switch on before flipping it over and use the plug to turn it on and off )
You would likely have to get a remote (like a dust collector remote), and attach the to the fan cord - leave the fan switch ‘on’ at all times, and then toggle the remote on/off when needed. The cord would have to be sandwiched between the fan and gasket, I’m not sure if that would cause any issues.
Several viewers have ordered this filter (I can see from my product linking insights) amzn.to/3QhjmQt It's cheaper than the Wynn, I assume it works similarly but I have no firsthand experience other than the Wynn filter.
I’ve built a few of these. In my opinion they’re not worth it unless you duct the intake or exhaust at least 10-20ft from the filter or they just keep recycling the filtered air right back through the intake. You can have 5 of these running in a dusty room all day and still find dust everywhere in between them.
Thanks for the input 👍🏻 I agree that it won’t circulate the entire room. I move mine around close to where I’m working when using the router, sander, miter saw, etc.. it seems to do a good job of capturing local dust close to where it is 👍🏻
I just ordered this set up. The cost of not having to replace furnace filters seems like a long term benefit. Also the merv 15 rating of the filter is beneficial to my lungs!! I also like how mobile and streamline the unit is. Thanks for the video and inspiration.
Would you not have to replace these filters as well? I could see the canister filters lasting longer than the furnace filters, but eventually they need replacement no? And could you blow off the furnace filters in the same way, or they're too thin to clean?
Built one out of same components and measured throughput with an anemometer. The throughput of my build was 1200 cfm making the air swap on my 5700 cu ft shop volume once every 4.75 minutes or 12.6 swaps per hour. Perfect!
Not so fast. Most of these will recycle much of the air around it only so it's much less efficient. Likely only 10%. To make it much more efficient you have have the inlet on the other side of the room. To make this happen you can use some type of hosing that will let you redirect air over a larger distance. The further away the more effective it will be. Well, maybe about 1/2 to 3/4 of the room size between the inlet and outlet.
I thought about flipping the fan as others suggest. Thinking about it, I like it as shown for a couple of reasons. It doesn't pull dust off the floor, that's what vacuums and clean sweeps are for. The dust is inside, keeping it from falling on the floor when it gets knocked around, and is easier to clean out with compressed air. If I was going to flip the fan, I'd probably want to mount it up off the floor.
Thanks! I have been looking through 3 different videos to locate your thoughts! I see the biggest pros are 1) dust is on the inside 2) easier to spray out with an air gun (if that makes sense for your filters)!
Filters are supposed to have layers with bigger "holes" on the outside for bigger particules, and smaller and smaller to catch the remaining ones as you go deeper, to prevent clogging it too fast. Having the fan pull clean filtered air would help it live longer too. But this way is way more convenient and if you clean it frequently it won't clog anyway ... the fan's motor might fail a bit earlier but not a huge financial loss either ... Even with my beliefs going strongly against it😄I'd probably build it the same way if I had to.
I needed this video about 5 years ago when I built my woodshop. Great video, no excessive talking, straight to the instruction and good pace of speech to action. Can't stand slow talking who drag out their videos to make them 15 minutes or longer.
Suggestion: Reverse the airflow to collect dust by drawing it first into the outside of the filter (greater available surface area) then push the air into your filter to clean it. I like your ingenuity!
@@mmcc_woodshop6288 You're pulling dust into the fan itself, though, which will reduce the efficiency of the blades and make life harder for the motor. It'll also run at least a little hotter this way. You might consider other ways to avoid a big blast of air in an unwanted place. If you blow out your expensive fan in six months, you might be disappointed.
This filter is designed to flow from the inside-out. The Nanofiber layer is on the inside. These are not the same as typical outside-in industrial filters. (All industrial Nanofiber filters are directional and will fail if used in the reverse direction.)@@RandomAxeOfKindness
@@mmcc_woodshop6288 Pro Tip: a fitted bedsheet placed inside like a bag inside the cannister filter barely reduces air flow and makes cleaning it extra easy as well as prolonging the life of the filter. Even with the current commieland inflation you can get a twin fitted sheet for like $12 off amazon or you can get 2 pack of fitted hospital bed sheets for around $22. We came up with this idea after using old filters like this that we cleaned with an air compressor and 90% rubbing alcohol because they were still mostly good but regulations had maintenance throwing them out and we wanted the already old air filters to last longer. We noticed that even using a blower or air compressor it got progressively harder to get the dust out of the filter requiring a flathead screw driver run between the slats sometimes to break it loose. Just don't let it get too full or it can get annoying trying to work the bag back out (grandpa had his as also part of his dust collection since we had so many.).
Great idea, and AWESOME video! I like the narration, simple, straightforward step-by-step, step-by-step, and just getting right into things! Thanks for this!
Very cool design and I am also searching for a better solution than the over-priced, under-performing shop air cleaners. Did you consider a pre-filter to keep the dust out of the fan motor and to reduce the cleaning intervals on your final filter?
Thanks Randall! I didn’t do anything with a pre filter.. the housing on the motor is closed on this fan, so I wasn’t too worried about that aspect. The canister filter is very easy to clean with a leaf blower, so no concerns there either, at least in my opinion
Great idea. I like the portability, and durability. It might seem a bit expensive at first, until I considered that the cylinder filter is reusable / cleanable. Reminds me of the extra up front cost of a K&N air filter. A cost that is recovered over time by not needing to replace disposable filters. Thanks for this great idea.
Cool idea. And thanks for including the shot of the readings on your Dylos particle detector to demonstrate that the setup is actually effective. That validates your idea for your viewers.
Thanks so much for making this video. I kept seeing all of this complicated builds and dreading having to make some contraption with a bunch of leaks. This is way work the money for the filter. I have the same filter on my Harbor freight dust collector so it looks like I will be buying another.
Turning my fan other way. Dog hair and dander are heck on motors. My grandfather used something like this in his wood shop in the 70s. When he remodeled their house every year he brought them in the room he was working on. My grand had OCD about dust. She deep cleaned 18 hours a day. You would never of known my grand had just moved the kitchen to the other side of the house. Now he even made /ceiling lights/fans that looked like car carburetors. Took box fan and put 4 filters in a box shape for dog hair in the basement walkout area. I really enjoyed this video. And I smiled at the blower. Again reminded me of my grandfather having to use one before bringing wood inside. I've never seen a wood shop as clean as his since. Lol
Nicely done dude. I have a similar set up for my dust collection. Just take the filter off once a month or so and blow it out with a blower. I love it. Dust in my shop may not be perfect, but visibly better than before and I can run it with the door closed.
That would definitely work, honestly I was being lazy and didn’t want to build a filter housing and thought that this would be simpler. I don’t think small dust particular should have any effect on the fan
But to his point it can be flipped the opposite way. The way @MMCC_Woodshop put it together it works well for collection near the location of the fan. Flipped around to blow upwards and pull air through is better for dust collection in the shop for general air cleaning. However, it will blow some dust around in that process. Just my opinion
This is one of my favorite air filtration videos I have seen. I love how simple it is, and I love how affective it appears to be. It would be great for my garage. Thanks for sharing.
Great post! I'm going to make the same thing. One thought - if you use three rollers on the bottom in place of four, there would never be an issue with uneven surfaces. Cheers!
Thanks! That’s a great point, I was honestly trying to come up with something as fast as possible with the wheels, it definitely could be improved. Thanks for the input 👍🏻
I love how politely you respond to all the redundant and/or obnoxious comments. Too bad no one has thought to suggest reversing the fan, or bothered to read your responses about why you chose not to.
Thanks for mentioning that!! I agree, there have been several comments - reversing the output/input would work, but that’s not what my goal of this setup is. I guess I should’ve explained my intentions better in the video. Anyway thanks for you input and for watching! Maybe the fan blade could be reversed, but I honestly don’t have much interest in trying to take it apart 👍🏻
@@mmcc_woodshop6288I believe they said that filter was ONE WAY ONLY: "This filter is designed to flow from the inside-out. The Nanofiber layer is on the inside. These are not the same as typical outside-in industrial filters. (All industrial Nanofiber filters are directional and will fail if used in the reverse direction.)" Otherwise, a nice idea! ;)
Absolutely brilliant! I've built a few of the inexpensive multi filter boxes (just taped together without any frame) with Lasko fans which worked well to keep household dust down. I keep one on each floor and run them for a few hours when out of the house. Unfortunately, the trades guys who recently renovated my house loved the idea as well, using them to manage the construction & drywall sanding dust. Since it's time to rebuild them, I think I'll give your design a try. I like the idea of filtering the air to MRV15 vs the typical MRV8-11 I've been using.
My only concern is the surface area of the filter versus the CFM of the fan. You didn’t comment on this in your video, but if the surface of the filter is too small for the amount of air being pushed through it you can prematurely destroy the filter, and/or burn out the motor in the fan itself. I have a Wynn Filter, I plan on reaching out to them to discuss this and see what they think. Otherwise I think it might be prudent to select one of their filters that is open on the bottom and add some way of cleaning the dust out of the box. Otherwise you’ve definitely inspired me to look further into this.
Hey Troy, good point. From what I understand, there’s a ratio (air-to-cloth) of the cfm to surface area of the filters. I haven’t yet found any reliable information on what an acceptable ratio is. I’m going to do a follow up video answering some other questions as well, but I’m going to calculate the true CFM and find out what the air-to-cloth ratio with this setup is. I’m guessing that 4000cfm is drastically overrated. Thus far, at least, I’ve had no issues/problems at all with the fan. I had the fan running for ~2-3hrs continuously earlier this week while doing some heavy router planing and the fan ran fine the entire time. If you did speak with Wynn, it would be great to hear if they were able to prove you any useful information
Probably not too big a worry as the fan doesn't actually push 4000 CFM. The 3D Handyman tested fans for a dust collection system and discovered manufactures exaggerate their CFM by quite a bit. The real world CFM he found for that fan was 1440.
@@mmcc_woodshop6288 I suspect if you contact Wynn Environmental that they’d help you with it. I mean you’re helping to promote their products, and they’re generally pretty knowledge and helpful guys there at Wynn. The other thing that would be nice is a discussion about noise levels. I know shops are noisy in general. But frankly I generally feel like something like an air filter could be made more quiet and doesn’t need to add a lot to that noise. I suspect a simple box lined with acoustical batt material and then you could put a two stage air filter on the intake in to filter out the bulk of the material. Maybe use a washable filter at the very front kind of thing.
Built this bastard 5 months ago. Amazing creation. I have a full gym in the basement and can't believe how well this works. I've noticed dust upstairs has also decreased significantly. I keep it on most of the time and just burnt up the fan. Just ordered a new one. Definitely worth it. Thank you for the video! Brilliant design!
Glad to hear that it worked well but bummed to hear that the fan ended up burning out! I wouldn’t recommend keeping them on over a few hours at a time, hope the setup continues to work well 👍🏻
Well isn’t that just the bees knees…I picked up an air cleaner a while ago on sale at the large online retail giant. It’s one of the kind they use after fires/renovations/asbestos abatement/floods in a house to clean the air and remove mold, etc. It moves a crazy amount of air and cleans the air to some crazy pure level, but it’s heavy, cumbersome, and the filters are expensive. I got some merv filter material and made my own, BUT YOURS is WAY more practical, especially for a wood shop. I didn’t read all the comments, but I’m sure many have weighed in with “expert” opinions. Dust protection is a multi-layer process starting with collection at the machine, then “free” air in the shop to keep the shop and machines clean, and then (for me anyway) still culminating with a respirator to keep my lungs clean. Only criticism is that at 4:23 in the vid you have your hand holding the block for the wheel down range from your chisel. DAMHIKT, but that can lead to the emergency room… Nice air cleaner though
Nice design. But dust collection guru Bill Pentz…..made a similar design but found that pulling air through the filters and putting an 90 degree elbow on top blowing the exhaust away from the filter made it much more effective. It keeps the air in room stirred up instead of re-cleaning the same air next to the fan over and over again. He used an in duct type fan and put a duct elbow on top of it.
high surface area of filter = lower velocity airflow = greater filter efficiency, use a cheap energy efficient fan on low speed for long duration to get maximum filtration. All of these YT filter videos are trying to use filters for purposes that are best suited for exhaust fans. VOCs are not particulate they are gases!
Filters are typically made for air to travel one direction. I would assume the direction set up in this video is the best use. There are filters made for air to flow the other direction for the setup you’re proposing. Mitch Alm did one a while back.
Thank you. 2 things 1 - I called the filter mfg’er and they told me the CAT fan was loud. I guess it's all perspective, but it's not loud. At 71 db its not as loud as my wet/dry vac or any power tool. 2 - with a MERV 15 filter, even when the fan is on high it does kick back some dust in the air. So it's not perfect.
Thank you so much for this video. This is EXACTLY why I love RU-vid. I do a bit of hobbyist powder coating. I simply don't have the space in my garage to have a full time dedicated booth to spray in. I was think into researching folding type spray booths, etc. when it occurred to me that what I really needed was a localized dust collector type setup that I could just put next to where I have the part(s) hanging to spray powder on, then I could also move it around and use it when I am doing sanding, etc. About the same time I happened onto this video... genius! Fan and filter ordered!
@@mmcc_woodshop6288 eager to get it going. Guess I’m spoiled by Amazon prime. Ordered that Wynn filter on Wednesday and still haven’t gotten a shipping email.
Great design. I'm looking around to build something myself. Hey, have you ever been told that you sound like Cam from blacktail studios? I think you do 😊
I did the same thing here, but instead ceiling mounted it and put it in a air pull configuration. I definitely can see the catapiller fan struggling to pull air "through the filter" so you may need to have something more powerful.
The simplicity of this looks awesome, but I don’t have the floor space in my shop. Do you think this is viable as a ceiling solution? Would those clips hold the filter in a horizontal orientation if I found a way to strap/mount the fan to the ceiling?
Great Job! The only change I would make is to put the filter on the INPUT side of the fan. That way you push filtered air through the fan to prevent dirt and dust particles from exposing the fan motor with micro debris.
Down side to that is the dust builds up on the outside of the filter, and gets knocked off every time it gets bumped. also keep in mind, if this fan was just being used as a fan in the shop it would be exposed to the same particulate.
Very cool video. I was about to build one of those boxes with 8 furnace filters but a kind stranger directed me towards this design and I love the look and simplicity. I already have the Cat fan and the furnace filters are still returnable, so time to get on it! Do you feel like the cost of your filter will be less than the disposable ones over time? Thanks for the great video.
Thanks! It depends on how often the furnace filters would need changed. Simply being able to detach the canister vs tear apart the furnace filter device is worth the cost IMO
This is what I love about RU-vid! What an awesome idea.! I just ordered the parts to make one of these. Excellent solution to fine dust extraction without all the time spent on building boxes and changing filters. Thanks for sharing your idea with the rest of us!
What if a person used a charcoal filter, almost the same as your dust filter but a cannabis charcoal filter has a hepa filter sock as well, fan and filter all build in when you get it?
I could literally kiss you. I bought this fan months ago but have been putting off building the enclosure that everyone else has on RU-vid because it looked like a whole project in itself. Your solution is so so very much cleaner. Thank you!
@@mmcc_woodshop6288 already done! Worked like a champ. I went a bit of a different route on the base / casters though. HD sells pre-cut round boards that were an exact fit for the bottom of the filter. I grabbed one of those, put 4 casters on the bottom and flush mounted 4 round magnets on the top. Boom, problem solved. Love it. Again, thank you so much.
Personally, I don’t ever see it needing replaced. This is the same style canister filter on my dust collector and my dust collector sees 100x more dust than this ever will. These canisters are designed to be cleaned and reused 👍🏻
This is the best idea for a shop filter that I've seen yet. It's simple, yet looks sleek and doesn't require construction of a frame. It looks like a commercial air cleaner. Thanks for sharing this idea!
I liked the design so I copied it; the only difference is that I made a round base with magnets, and I bought the mustard yellow Caterpillar fan. I noticed that there is a bit of blowback out the top of a fan, regardless of the speed setting. To all of those talking about reversing the fan direction, the filter is reinforced on the outside, so he has the fan direction correct. By blowing into the filter, the reinforcing keeps the filter from blowing out.
Good points and thanks for the input Joel! I didn’t notice the blowback until others mentioned it, but I do agree that it’s there. I’m not certain, but I would imagine any blowback would recirculate (like a loop) right back into the ‘inward’ suction. With the set up as is, I would imagine the suspended dust would gravitate toward the ‘pull/in’ stream of air and bypass the blowback. Regardless the setup still appears to draw in a lot of air - I wish there was a way to see the actual air currents!
Maybe adding another filter to the chain will solve the issue. I’ve found that each filter move 1550 CFM, for a 4000 CFM fan maybe 3 or 4 filters in chain will be the optimum.
Love this design. I built a frame version. Thought of the cannister filter but you have to go through a lot of MErv14 filters to break even on a $270 cannister filter. How long do you expect it to last?
Thanks! I’m not sure if the filter will ever wear out.. you can take the fan off and clean the filter out with a leaf blower so it should last several years, hopefully anyway
Agree on the direction, but the nice thing about this design is the dust stays inside and it is easy to move the unit outside and blow off vs. it caking on the outside where it can easily fall off on the floor when moved. You could cut the bottom out and mount a simple shop pail to collect stuff (knocked off between uses). I really like its simplicity.
@@SAWimp1 it's a lot easier to get it everywhere when it isn't contained, too. What you are discussing is a relatively small difference in filtering efficiency.
You should take the switch off the back of the fan and turn around the fan so it sucks the air from the outside of the filter to it's inside. The logic is the surface area outside the filter is a larger dust input than the surface area of the fan. You will gain 360° dust collection as well.
I understand the desire to suck the air through the filter but these filters are designed for a dust collector and they blow the air through the filter trapping dirt on the inside so I think he has it right. Think of the air flow arrows on a furnace filter, the direction the air travels can matter. and as he showed it keeps the dirt inside so it can be cleaned, not sure how that would work if the dirt was on the outside of the cannister. just a thought.
@@garydrawson7709 You really don't want abrasive dirt coming at your fan motor which is another important consideration for reversing the fan direction. It would keep the fan and it's motor cleaner and operating longer although it is easier to clean the filter like you mentioned. If going for a room air purifier I would reverse the fan and the other benefit is negative pressure would help keep the fan and filter together for less chances of a leak between fan & filter.
Interesting points here from everyone! So the fan motor is a sealed motor on the back side, so the dust shouldn’t reach the internal components (the way I understand it anyway). I’m not certain, but I believe the canister filter is meant to have the air flow from the inside to the outside, not in reverse, so I’m not sure if it would work with the fan reversed - HVAC filter panels would likely be more appropriate in this situation. Also, I mainly made this for ‘spot’ filtering near where I’m working at the time. My shop is a moderate size with a high ceiling, and technically I don’t think the fan will pull air from ~20 ft away, even at 4000 cfm. So far, my experience with using this the way it is near where I’m working has been excellent. I’m sure there are plenty of variations that this could be set up but I’m very happy with the performance of it so far.
air flow is determined by reinforcements, the more a filter loads up with particulate the more air pressure it must resist. It is cheaper and easier to reinforce for only one direction of air flow, almost all air filters are designed for one way airflow...
Seems like the filter is being used backwards. Shouldn’t the fan be pulling the air through the filter and out through the blades, as opposed to pulling the dusty through the blades into the filter?
@@mmcc_woodshop6288 Interesting, that would keep the dust from accumulating on the outside. The fan motor, I would image, would have to be sealed to prevent clogging. Anyway, good video.
This is great. I set it up and it seems to get a lot more air flow pulling the air through the filter. I'm also thinking of adding a pre-filter to the outside to catch bigger particles and extend the life of the expensive filter. This is how the jet air cleaner works.
I like this idea too. I was thinking maybe have it pulling debris through the filter to save the motor bearings from all the dust. The only issue is the dust that's captured is now on the outside of the filter. Hmmm. Not sure. I do like the ability to blow the dust out of the filter from the outside. Both designs have their plusses and minuses.
This is FANTASTIC, LOL BUT EXCELLENT IVE BEEN USING A 1950 SEARS HOMART AIR COOLER, B-4 A/C IN HOMES IT MOVE 200 CFM, I PUT MERV 12 HVAC FILTERS,2 IN A V SHAPE, IN A CARD BORD BOD & USE A LOT, ALOT OF TAPE 0YOU MUST HAVE IT TOTALLY SEALED ITS GREAT FOR ALL TRADES THAT CREATE DUST DURING RENOVATION S I CUSTOMERS HOMES ITS UNBELIEVABLE BELIEVEABLE JUST HOW GREAT IT WORKS TOHE MOTOR IS A 1/4 HP & ONLY DRAWS 4 AMPS BUT DOES TAKE UP A LOT OF ROOM SO I'LL BE BUILDING 2 OF YOURS GREAT VIEDO, GREAT IDEA PERIOD!!, THOMAS PAYNE, MASTERBUILDERS, THANK YOU!!
I don’t think it would ever need replaced personally, these filters are designed for dust collectors and to be cleaned and reused. The filter I have on my actual dust collector sees substantially more dust than this and it still works perfectly after being cleaned 👍🏻
Quick, simple, effective, and you end up with something that looks like it came out of a factory, not a scrapwood cobble-up. What's not to like! Sadly for me, I don't need a filter... I was surfing for dust separators to add to my shop vac, and your video looked to good not to watch. Really well produced and interesting, thanks.
@@mmcc_woodshop6288 : Ironically, yesterday I found a cheap 4 gallon stockpot which is the correct depth, and identical diameter to the shop-vac bin I want to extend. I decided to try this approach after watching your video, so indirectly you have helped me a whole heap! Thanks. 👍 😃
Here’s the link… from what I recall if you buy the filter it comes with the clips - I’m not 100% certain on that but am just going off memory. wynnenv.com/products-page/woodworking-filter-pricing/fgl-l-4/
How efficient and simple your design is! Thanks so much for coming up with it and making this video and thanks for leaving out the typical annoying music. Have you determined the maximum fan speed that can be used? And best speed to have it running to clean the air while you’re working around the shop? I just ordered everything to make this and decided to go one step easier by using 15mm round magnets from Findmag. They come with a countersunk screw hole so I’ll just drill a shallow hole in the caster block instead of chiseling and gluing. The Wynn MERV 15 filter ended up being about $300 after shipping and I tried looking at cheaper filters. After some research to see what a MERV rating even is (Minimum Efficiency Reporting Value) , it seems that a minimum of MERV 13 should be more than adequate for shop dust since that rating is good for hospitals. After looking for a cheaper MERV 13 that would fit the fan I decided to quit dicking around and just get the Wynn you used. You had it figured it out, it works with the fan, and they sell it for woodworking dust collection plus they say that it’s good for 100’s of cleaning cycles! Several people commenting seem to think this will work better if the fan is sucking air through the filter instead of blowing into it as in your design. I will point out that Folks who want to do that will need to use a different filter. In Wynn’s description of the 35C222NANO Cartridge Kit is printed: “This filter is designed to flow from the inside-out. The Nanofiber layer is on the inside. These are not the same as typical outside-in industrial filters. (All industrial Nanofiber filters are directional and will fail if used in the reverse direction.)” Looking forward to breathing cleaner air!
Thanks for the comment Kent, I’m not 100% sure on specifics - I just turn it on either speed 3 or 4 for maybe 10-15 minutes while I’m cutting in the area. These filters are meant for dust collections which will see a ton more dust than this orientation, unless it’s heavily heavily heavily used, I doubt it would ever need replaced (it’ll need cleaned for sure). And I agree 100% on the orientation, although I can see why others would try it reversed. Personally this is the way I would want it for what I was trying to achieve.
Thanks! Yes, I have a similar filter on my main duster collector. This video is to create a local filter that sucks in all the dust that my dust port misses on the tool connections (my miter saw is terrible with dust collection).
