Thanks Patrick! Glad the video was helpful! 👍🏻

Thanks for watching! I absolutely love this filter so far and have actually gotten a second one 👍🏻

You're wasting your time,the fan will blow whatever dust that's collected in the filter back into the air again.

@@coffeeman9475 Why don't you make a video and show us. I don't believe what I can not see...

@@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 agree, those were my thoughts as well!

Thanks for watching and the feedback!

Thanks Christopher!

Simplicity was the idea behind it! 👍🏻

Thanks for watching! 👍🏻

Sounds like a perfect set up! Thanks for watching and for the feedback 👍🏻

Don't waste your time,the fan will blow whatever dust that's collected in the filter back into the air again.

@@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.

@@coffeeman9475 You just need to clean the filter regularily so the air flows through the filter.

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.

Thanks for watching!

Nice! The simpler the better, thanks for sharing 👍🏻

You’re welcome and thanks for the feedback!

Thanks! 👍🏻

Thanks Rodney! You'll get quite a bit better filtration with a MERV 15 opposed to the 11. Best of luck incorporating this into your setup!

Thanks! I’m really happy with my setup 👍🏻

@@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.).

Thanks Nick!

Sweet, thanks for watching and the feedback!

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.

Awesome, thanks for the feedback and good luck with your setup using it!

@@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.

Thanks David!

The great thing about the fan he uses in his is that it has a sealed motor. The debris won't get inside.

Thanks for the input and feedback! 👍🏻

If you turn the fan around the dust will accumulate outside the filter Isn't the whole idea to trap the dust?

Thanks!

@@mmcc_woodshop6288how often you have to replace the filter?

That was the goal with it 👍🏻

Sounds awesome! This setup works great in my experience, I’ve actually gotten a second one since this video 👍🏻

Thanks Sean! The EGO leaf blower is 10/10 👍🏻

Thanks Greg! The plywood style box is exactly what I was trying to avoid.. very happy with the performance of this setup so far 👍🏻

Nice, glad it worked out for you! 👍🏻

Thanks Peter!

Thanks Jeff, exactly what I was going for. These filters are incredibly easy to clean out with a leaf blower/air compressor/etc

These filters are really reusable? You don't have to replace these? I'm thinking about what to use in my basement to clear out possible mold.

I’ll have to check that video out!

Thanks JP!

Thanks for watching! 👍🏻

That should work fine to circulate the entire room air. Im trying to avoid a blast of outward air from the fan in this setup 👍🏻

@@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.

@@mmcc_woodshop6288 6 months later -- have you noticed any negative impact on the fan's performance using it to pull debris through the fan?

My fan lasted 5 months but it was running constantly. Definitely makes a difference.

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

You nailed it with this comment.. those reasons mentioned were a huge factor in why I set it up this way

That only happens if you really bang it around. They are designed to trap the dust. Moving it aroudn will not dislodge the dust.

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.

Can you make a carbon one for Vocs?

Thanks Mark!

Thanks, exactly what I was going for!

Exactly what I was going for with the design! Thanks for watching 👍🏻

Thanks David, exactly what I’m going for with this setup 👍🏻

The smallest particles, which are most dangerous for your lungs, will stay suspended in the air for a very long time.

@@percyfaith11 Have been working in wood for over 60 years and still don't have much in the way of dust masks... A lot of this crap is so overblown...

Nice! I actually bought a pack of furnace filters to use and sent them back after I thought of this 😆

@@mmcc_woodshop6288 I just bought a set of 8 MERV14 furnace filters today and that was before I watched this. Now I'm wondering what to do. Lol

Send them back or keep both and see what you think works better 🤷🏻‍♂️ I had the same idea with the furnace style filters but this didn’t require me to build anything 👍🏻

It really is a health hazard. I feel like the higher rated canister filters should be a requirement for dust collectors. Thanks for watching and your input!

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.

Thanks! This fan has an enclosed motor, so my understanding is that dust shouldn't be too much of a concern (hopefully!).

The motor is enclosed, which is why it's the preferred motor for this build.

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! ;)

Thanks Dean!

Thanks for watching!

Nice! I’ve definitely considered making a few more and mounting them up in the ceiling/walls

Haha, thanks! Glad it was helpful, good luck with it!

@@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.

Thanks! It was a quick and simple solution 👍🏻

Thanks man! Thanks what I was going for!

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

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 👍🏻

It couldn’t be any easier! Thanks for watching!

Thanks for the feedback Bob, good luck with your setup 👍🏻

My lungs are worth the price!

Thanks! Great call and enjoy the clean air!

Thanks J!

That’s a great idea.. I was actually trying to avoid stirring up air and keep it localized, I definitely see that perspective though 👍🏻

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!

@@mmcc_woodshop6288 You will need to use a filter designed for pulling air through vs pushing .

I'd also add a sock to the outside of the filter, makes the filters last much longer

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.

😂😂 If I ever come up with a DIY air fryer I’ll definitely make a video on it!

@@mmcc_woodshop6288 it's only for cleaning the shop air?

Technically the same principle, so if you were to add a beefy electrical heater inside of this filter you'd have your air fryer!

Thanks for the feedback!

Haha nice! Thanks for watching and good luck with the upgrade!

Thanks for watching and for the feedback!

Thanks Stan! I’m really happy with it so far, a pre filter may definitely help!

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.

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

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.

Great video, great concept. I like it a lot

You’re welcome and thanks for watching!

Thanks! Simple was the idea!

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.

Pretty sure this is a sealed fan motor. I’ve seen it used on other dust filter videos and I believe they said they chose it because it is sealed.

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...

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

I think the Catepillar fan has a sealed motor. And those pleated filters for dust collectors are meant for the air to go from inside-out.

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

Thanks John! 👍🏻

Thanks Tom, exactly what I was going for 👍🏻

Good point, didn’t think of that!

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.

@@csimet its a lot easier to clean the outside of the filter than the inside

@@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.

Are they? It's the same filter used on his dust collector where air is pushed through from the inside 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!

I also get blowback with this exact same design. Too much back pressure from the Merv15 filter? Overall this is a very effective and simple design.

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.

Thanks for the feedback. I’m if really kicking up dust, I’ve noticed it all the way up around my lights, so I see the rational of a filter on the ceiling. Trapping the dust at the source (what I’m trying to do with this video) makes more sense than to capture it after it’s airborne 👍🏻
