You truly are a man of the people. Kudos to you for sharing the science of air filtration from knowing the filtration rate, the static pressure, and understanding CADR, and not only explaining and demonstrating has got me wanting to know more. I notice I'm not the first 300 comments on this video but I figured I would comment anyway as I believe you doing a giveaway is so wholesome. I look forward to buying one when I can save up the money. My son is allergic to almost everything and suffers daily from ezcema and allergies. I feel this is the most affordable answer especially the one with the charcoal to filter out the house. Thanks Sir for sharing.

Honestly, I cannot tell you how happy this video makes me! As a self proclaimed filter nerd, it makes me feel so validated that someone cares as much as I do. Your work here is invaluable! The 3M 2800 filters have been my go to for years, and I love the idea of using them in a HEPA filter configuration. As someone who bought a IQAir last year, I have been disappointed in it. It filters great, but the bearings in the fan have started to go. I am dreading having to send it back. I would love to be entered in the contest so I could try out one of your marvelous filter boxes instead. Thank you for all of your hard work. This information is the best I have ever seen put together in one place!

@dsluo 2 месяца назад

Tangentially related, but have you considered looking into DIY approaches on the dust separation side of things? One of the projects I have on the backburner is reverse engineering the Harvey G700 cyclonic dust separator - using a dust collector fan, short lengths of 8 inch PVC pipe from Amazon, and 3D printed adapters, fittings, and fins to replicate the functionality of a $2500 machine. I'd love to see your take on it.

@The3DHandyman 2 месяца назад

I very much like that idea and I have something in mind. Just need time to test it out. Maybe later this summer if all goes well. Thanks for the comment!

@andyporter3640 2 месяца назад

@johnhufnagel Месяц назад

The switch to plastic/aluminum (especially in black) and the forthcoming prefilters (also in black) is going to make me buy one or more of these kits. They're looking clean enough to go in a room and NOT piss off the wife. :D Now if only it were possible for the filters to be black themselves, then the whole thing just disappears basically.

@The3DHandyman Месяц назад

Happy to hear you like the color combo! I think it's pretty slick myself. If you use black duct tape to apply some black sheer mesh/fabric to the outside of the filter as a pre-filter, the whole thing does turn black. It's pretty straight forward but I'll be doing a video on that in the next two weeks or so.

@ThaneACovert 2 месяца назад

I appreciate all the testing and the graphs! I'm just upset I found your channel after building a CR box with 4 3m 20x25 filters, a lasko box fan, and packing tape plugged into a smart switch. Thanks to your channel, I have recommended these filters for family and friends currently battling seasonal allergies. My plan is to build a quad filter setup into a more cost effective and better performing side table similar to Ikea's starkvind table with replaceable 3m filters and maybe a UV-C light inside.

@The3DHandyman 2 месяца назад

Sounds like a great use for that Ikea table. People also make 3D printer enclosures out of that table, I believe. I have head a lot of comments about the UVC lights. Be careful to completely shield the light, UV-C is some nasty stuff! Thanks for the comment!

Great video. The battle with dust is a constant struggle in my shop. I have a couple different DIY filters in the shop now; always looking to improve the efficiency and ease of maintenance. I’m looking forward to seeing your plans for woodworkers to use. I appreciate the information on the impact of air turbulence in the shop. It is a good time (weather and shop temperature) to turn off my fan to test whether it has been hindering or helping the dust control effort.

@brandonwright4314 2 месяца назад

Man, I can't wait to see the results of the cartridge filter test. I purchased one of the Cat fans for the powder coating spray booth I'm building based on your recommendation and it'll be pulling through some similar cartridge filters. I _should_ be using an industrial tube axial fan but the Cat is a far cry from the $1500 alternative. Even running three Cat's will be significantly cheaper. Hope it'll do the job.

@The3DHandyman 2 месяца назад

Spray booths are a challenging build! They have a lot of needs. I did have success with the cartridge filters and the CAT fan in the upwards "pull config" more so than the downwards "push config". That said, I had even more success with the 12" inline fan that handles static pressure better. Also, ducted filtration rocks. It's a bit like a budget downdraft paint booth. I'll cover all the details on the cartridge filters in the upcoming video and I already have a video out on ducted filtration if you haven't seen that one yet. Thanks for the comment!

@PeterWoolstonMusic 2 месяца назад

It’s so good to see you publishing again - great stuff! I followed your guidance & got the CAT fan and I’m looking forward to your next video about woodworking filters so I can finally go with one of them or import the disposable filters from the USA… either way your work and the v3 is awesome! I went to purchase your new kit but it will cost me almost NZ$800 as the shipping alone is NZ$403 … so I think I’ll have to download the plans & DIY even though I want to buy it to support you … unless you somehow select me for the giveaway CAT fan model & I only need to pay shipping 😜

@The3DHandyman 2 месяца назад

That quite the shipping bill! I one shipped a vacuum former to Japan for 700USD. It could be worse!? haha. Yeah the pans will suffice, unless you win the drawing, of course. I'll have the Canister Filter video out in about 2 weeks. That one will be easy to make and they work great too. If you want "The Claw" attachment, I'm sure it is cost a fraction of that NZ$403 to get it there. Thanks for the comment and sorry for the long wait!

I’ve been searching for some proven solutions for my small garage shop that don’t break the bank and might afford me the opportunity to make use of the open rafter space. I could absolutely envision mounting a model B type system on a pair of rafters with the fan intake protruding down into the workspace. Excited to see more of your research!

I see a lot of stupid people advocating for pull direction in most youtube videos with Diy box fans. suction power is so limited. even strongest vacuum cleaner available needs it close enough to suck a dust. imagine a box fan not intended for static pressure or suction.

@@The3DHandyman Yeah, not a problem. And I do have a few q's. I'm curious about the footprint and throughput of the Model E and that smaller inline Model B-ish version with the 30x14 filters. I've got a under utilized 20x20x40 corner that perfect for such a beast. I'm guessing that info is incoming in a future video. Also, have you tested filtering any harsh 3D printing filaments through the carbon filters with good results?

@The3DHandyman 2 месяца назад

The footprint of the Model-B is about 3 inches wider than the filter, so the 14" filter model would be about a 17" square. I'll need to add dimensions to the listings. Forgot about doing that again, haha. The smallest Model-E is an 18" wide, but because it is circular you can turn it to vacuum it and it wont get any wider than 18". The 14" B will be 24" diagonally, so if you want to put a prefilter on it and vacuum it, it takes up a lot more space if you need to turn it. I will be doing some resin printing tests when I get a chance. So far, all I have tested the carbon filter with is FDM printing. I suspect it will work well but I don't know about the longevity of the carbon when I hit it with that resin stink. Hopefully that video will be out in about 2 months or so 🤞 Thanks for all the comments, Albert!

I've been doing a lot of research on box fans vs HEPA filters and it seems to me from the data I have seen across the Internet. In most scenarios these quad filters do more work at cleaning the air then HEPA filters with regards to allergens and other ultra fine or large particulates simply because they have more passes at cleaning air and more volume. CADR seems to be a better metric for determining how much filtration a fan can do and MERV 13-16 seems to be the sweet spot because of high airflow. Thank you for making the elegant and functional fans more accessible. They look very excellent quality and would love to try one out in the shop!

I really appreciate your attention to, and explanation of, the details about each of these fans and filters. This is exactly what I'm looking for as I research ideas on how to improve the dust reduction in my shop. Thanks!

What an exciting drop in my subscription feed! Looking forward to the future videos. Might be time to graduate from my air king and 4inch Nordic pure filter

@The3DHandyman 2 месяца назад

The air king and a 4" filter is a fine choice, but the quad filters are the next level. Thanks for watching and the comment!

Hi 👋 I was just watching your video about diy air filter and was hoping maybe I would be one of the 300 comments? 🎉 at any rate I really appreciated your video and can't wait to do some due to all the yuck in our air it's terrible! Thanks so much

@The3DHandyman Месяц назад

You are one of the first 300! My comments don't count and there are a lot of those in the mix. Thanks for watching!

@comrade33dawn 2 месяца назад

Love your videos. They're informative and instructional and the research is well done. Looking forward to the next videos. Here's to cleaner air!

Thanks for watching, comrade!

@chadcarrington1218 2 месяца назад

Thank you for all your work and testing. Having all this data to view on your website is very helpful. It's a lot more complicated than just sticking a fan on a filter!

@The3DHandyman 2 месяца назад

I'll have even more data up there later this week and even more some day after that. Thanks for watching and commenting!

@volvotango8363 2 месяца назад

Great job on this even more in depth analysis! Would love to see some future designs and sourcing for even higher MERV numbers.

@abzz132u 2 месяца назад

So glad to see the upgrade and changes to the kit. I’ll definitely get in touch when I get back to StL in the next month or so! Save some of that AK shipping.

@The3DHandyman 2 месяца назад

Thank you! Fine idea. Good to hear from you again

@neilbaltes3469 2 месяца назад

Outstanding!! Information that brings health home economically!! Life happens and I've not had a chance to build one. Things are slowing down and love the idea of purchase. Thank you so much for your videos and ingenuity.

@The3DHandyman 2 месяца назад

Thanks for watching and considering a purchase! Happy to hear things are slowing down a bit, life can happen a bit too hard at times. I appreciate the comment!

@Lyoishi 2 месяца назад

@The3DHandyman 2 месяца назад

It is a quest that one day may be completed satisfactorily. We can only hope.

@thaught9475 2 месяца назад

I've been following your channel for a while and seen various iterations of your projects, and i gotta say that i really appreciate your designs and willingness to make this information and your designs available to your viewers. I picked up some filters this last weekend and I'm looking forward to making your Caterpillar drum fan model soon. Could always use more filters for my shop, so I'm looking forward to your giveaway as well. You've earned my subscription.

@The3DHandyman 2 месяца назад

Awesome. Thanks for subscribing! I should have the plans available on the website later this week

@AySz88 2 месяца назад

Wow, this had to take so much meticulous work, and is being offered so generously. It's not too hard to find, but don't forget to link to your own website!

@The3DHandyman 2 месяца назад

Thank you! I just replied to another comment saying the same thing. I need to update the website with data from this new series, but that may take me a week or so.

@tylerhuttosmith 2 месяца назад

I agree with everyone else in saying your videos have been instrumental in going about this DIY! I’m working on a modified ceiling mounted version using the Cat fan. Can’t thank you enough! Also bought the 3d printed parts and they’re perfect.

@The3DHandyman 2 месяца назад

Happy to hear the parts worked just right! Thanks for the comment, Tyler.

@mrribbot9673 Месяц назад

This video was recommended to me after watching a video from the Healthy Home Guide. Thank you for putting this video together, tons of great info here... done in a clean, professional way. With the anticipation of fire season again this year - living in BC, this is very helpful

@The3DHandyman Месяц назад

I think the final script for this was version 5 or something like that. Happy to hear that it got the job done. Thanks for the comment!

@DadOmega 2 месяца назад

Great information. I have a box fan filter in just about every room of my home. Hanging from the ceiling is a great idea.

@The3DHandyman 2 месяца назад

The box fan filter is the DIY standard. Excellent choice

@PeterCharlesworth 8 дней назад

So awesome - great data. Would love to see some of your thoughts based on testing quieter computer fan builds for use on night stand or in office

@Kiwiphotog01 2 месяца назад

Great information, thank you very much. I'm building one unit for the home and one for my photography studio, helping keep the gear clean and free from dust on the CCDs which is really important. Thanks and looking forward to the next video

@The3DHandyman 2 месяца назад

That's a great use for these. I bought my Sony that I shot this video with used and the sensor was filthy. Got to keep them things clean!

@PowerNk1 2 месяца назад

Amazing video! Much respect. I need to put one of these with a charcoal filter next to my 4x8 foot uv printer!

@The3DHandyman 2 месяца назад

Thank you! Actually, I have talked with someone that has a UV printer. They called it a "stinker". That says a lot, haha. One of the 12" charcoal canisters should help with the funk.

@WillPierceMN 2 месяца назад

I would love to see a video specific to your 3D printer room and what mode to use.

@The3DHandyman 2 месяца назад

I plan to talk about that a lot in my upcoming video on VOCs. Hopefully not more than 1-2 months out on that 🤞

@SpiderWaffle 6 дней назад

It's great to see the scientific research and data on this. I always wanted to see this but could never find anything of much significance and didn't have the means to do much significance myself. Finally the void is being filled and it's of major significance and benefit to the world.

@frantyk 2 месяца назад

Awesome design work, and love the level of detail you've put into the testing. I've been holding off on building one of these due to space constraints in my garage shop, but that will be changing soon, so I am super excited to see that you've continued improving these designs. My current setup (shop-vac with cyclone for most tools, dust extractor for sanding, and ceiling mounted air filter) does an okay job...but there's still TONS of fine dust everywhere the next day when it all settles out of the air. Definitely think the Cat drum fan kit is going to be on my shop upgrade list here really soon, unless of course the testing on the canister filters pushes things in that direction.

@The3DHandyman 2 месяца назад

Thank you! I will get into the same level of detail with the canister filters designs. Spoiler alert... I like canisters for ducted filtration much better than Axial fans. Axial fans and large disposable filters are a much better combination. If you cant go with a ducted design, the Cat fan and some 20x30in filters are the most efficient option by far.

@MrRustyjackson 2 месяца назад

That is over the top crazy interesting. I love the testing and data you share. I built a previous version of one of your filters but now I see I should pull the air down and out which is opposite of how I did it.

@The3DHandyman 2 месяца назад

It works in both ways. In some cases the up method works better. The concept deserves a video to itself and it will get one some day soon.

@SAdeimosSA 2 месяца назад

Looking forward to the woodworking filter discussion. I will probably build an inline fan version with venting.

@The3DHandyman 2 месяца назад

Nice. I hope to have that out in 2-3 weeks

@jreitman2007 Месяц назад

am beyond impressed by this video. so much engineering, backed by data, etc. Super stoked to buy a kit, but i'd really love to have one of the give-away units.

@The3DHandyman Месяц назад

You will be in the drawing when the comments reach the threshold. My comments don't count and there are a lot of them... Thanks for watching!

@dennisseemann571 2 месяца назад

Excellent Engineering! I am on the verge of making one for my garage woodshop when I came across you video, many of the ideas I had reguarding the build will now have to be reconsidered based on your work, will take a look at your etsy shop and see if its a better idea just to purchace a premade one or get some of your plans and proceed from there. Thanks again for your willingness to share all your hard work.

@The3DHandyman 2 месяца назад

Thanks for watching and considering a purchase! I should have the plans up on my website later this week if you decide to go that direction

@victoriage 2 месяца назад

@user-sq9ip4lv5e 2 месяца назад

Thank you for your insight, I was trying to find something to remove the pet hair/dust bunnies and I think this is exactly what I need!

@The3DHandyman 2 месяца назад

These work great for just that sort of thing! A lot of people have commented on how much they help with allergies

@herbveitenhans3285 Месяц назад

I just found your channel. Thank you for compiling all of the data. I also 3D print in my home and want to reduce the Voc’s even from PLA. I’ll start by building the caterpillar fan and then make a small one for the 3D printer room.

@The3DHandyman Месяц назад

Awesome. Happy to send a little inspiration your way. I hope to have my video on VOCs out this summer. PLA does have a bit of a sweet smell that isn't foul, but probably isn't too good for us.

@AlbertoBarrera1 2 месяца назад

Once again great work on your video, I recently bought an AC Infinity Cloudlift S12 also on Healthy Home Guide's advice, so it's great to see you using it in one of your designs as well. I also took advantage of the recent Costco deal on the 3M MERV 14 filters, getting 4 4packs for $35 each pretax, so here's to hoping that they run that sale again 🤞

@The3DHandyman 2 месяца назад

For sure! The MERV 14s were $44 here for 4, but that's still a great deal. I also like the black trim on the filters. Classy looking. Forgot to check today if they still had those. The had MERV 13s last year. I think a lot of the cost of the filter is just in shipping. The Cloudlift is a great fan all around. Really impressed with AC Infinity's product lineup all around. Thanks for watching and commenting!

@JS-ts9xo 2 месяца назад

I made the cat fan filter for my garage wood shop and it works wonders. Don’t even need the when air filters on the ceiling.

@frijoli9579 2 месяца назад

Awesome work man! Looking at the B with the CAT fan, and the Wall fan version for the house. Really interested in the wood working fans for my new shop.

@The3DHandyman 2 месяца назад

Awesome! Happy to hear you like the new designs. Let me know if you have any questions at all

@WesleyKennedy 2 месяца назад

Amazing work! I really appreciate what you are doing for the community. Have you looked at the 20" DeWalt 5000cfm fan for around the same cost at the caterpillar?

@The3DHandyman 2 месяца назад

I have not, yet. A few people have mentioned this one though. Personally I do like the enclosed motors so that the fan can more safely run pointed into the filter box. If I'm looking at the right fan, it doesn't seem to sport one of those. It is probably more powerful than the CAT fan though which would be nice. Thanks for the comment!

@davegilliam7729 2 месяца назад

I really enjoy this series and the model B design looks sharp! Curious if you’ve done any testing using a centrifugal fan, like one from a furnace? Thanks for all the work and info you’ve shared!

@The3DHandyman 2 месяца назад

Glad you are enjoying the videos! I hope to do a video on a centrifugal fan later this summer if all goes well. I got a second hand furnace blower over a year ago but haven't had the time to mess with it just yet. The one real down side I see to them is that they pull a lot of power compared to inline fans and axial fans. They are designed for high static pressure environments though, so that makes them well suited for his sort of application.

@brianfolding40 7 дней назад

I'm so thankful that I found your channel! Can you recommend the best option for my man cave? I frequently have friends over for darts and sometimes there's smoke and I don't want the odors drifting upstairs. I'm sure that smoke/odors are hard to control or eliminate but it seems like your designs would work a lot better than most of the brands of "purifiers" on the market.
