Which particulate detector do you use?
Where's the link to the dewalt battery adapter? Thanks!
The biggest issue I see with your rating is that you are measuring are speed, rather than what is being moved (1100 ft/min is not the same as 1100 cubic feet/min, as you need to multiply airspeed by the swept area of the fans).
Agreed. Definitely worth reuploading a revised video that doesn't include referring to f/m as cf/m when using the tester.
Eh, even if you adjust the reading for swept area you'd also have to adjust for the different air speeds across that swept area to get closer and closer to a precise number. In the end, it doesn't matter much since he was looking more for a ratio than a precise reading. An interesting test, though, would've been 5 minutes of fog machine followed by running each of the different air filter machines to see how long they take to bring the PPM back down to baseline, apples to apples.
Doesnt matter since the inlet/outlet surface area is fixed, so in this case flow speed at the outlet is a proper indicator of change
@@aloha13randonnn an indicator of change, yes, but not an indicator of value.
@@chaseweeks2708but in situations like this where it would be really difficult for a layman to ACTUALLY work out the value, sometime change is a good enough indicator to tell us whether or not something or worth doing.
13:40 1,181 ft/min is 13.4mph. Milwaukee rates it at 13.5mph per the spec sheet you showed. So right in line
It's a beast! Happy to see that the kit worked well for your design. Because I sent you a few extra clips for the larger filters, I've updated the kit on Etsy with an option for 56 clips. Thanks for the mention!
Build a version that takes 4" thick filters or 5" (4+1). Higher initial expense, but will last way longer without restricting air flow. On mine, I use a 1" MERV 8 in front of the 4" HEPA filters to catch the big stuff.
Only ever need to change the pre-filters. Everyone needs something like this in addition to a dust sucker.
I'd be interested to see a video after 6 months of so of use with a cost break down. How much to the filters cost? How often do you need to replace them? Cost analysis between commercially available air filters vs the DIY ones. What costs more over the long haul with the cost of replacing filter etc. This video was awesome by the way. Thanks for sharing!
just an idea what if you used that same fabric and made a sleeve for the whole box. cut a rectangle on the ends you can use Velcro that way you could take it off and wash it.
This is very similar to a Corsi-Rosenthal Box (not sure which came first) which can be used to filter the air when people are congregating indoors. They've been really helpful in schools or businesses where the building's ventilation system can't keep up with crowds etc. and folks are at risk of getting sick from air-spread diseases.
Very cheap to make; you just need some tape, cardboard, four filters like you've shown here, and a box fan. Lots of free designs and templates available online.
Definitely making this!
I've done something very similar to this in the past, but the large fans didn't last. The unavoidable fine dust that gets by or through the filters wreaks havoc on the fan motors. I got tired of replacing them, so I got my hands on old 3 speed furnace blower assembly, It's a little noisier but still going strong, and the CFM's are fantastic for my needs, even on the lowest speed.
Your video was both informative and entertaining! 👍 I loved watching the project come together, and I learned so much along the way.
A small improvement I might suggest is in place of clips to hold the filters in, and installing mesh prefilter on each one, is you could potentially build a door for each side that has the mesh preinstalled and serves the function of holding the filters in. It's more work but it saves work down the road of installing the mesh every time you replace the filter. You could theoretically have the prefilter be permanent. overall great build
The anemometer you have measures in feet/min. That's how far the air travels over the course of one minute. To get cubic feet/min you need to multiply the value you get by the area of the fan's exhaust (which the anemometer can't possibly know). If it's 18 inches in diameter, that'll be 1.77 square feet, multiplied by 1181 ft/min gives 2007.7 cubic feet per minute. Not quite the 3400 claimed in the specs, but they might be fudging that number by including air that gets pulled around the outside of the fan and so on.
Yea, I definitely did my math wrong but still underperforming!
Awesome idea!
Really cool project for a fair price. Really enjoyed the vid. Well done as always
One way commercial shops cut dust down is by exhausting fine dust to the outside. So simply having something that can suck the shops volume out a few times per hour would be one of the best ways. Looks like your filter works very well too.
Yeah but then you end up discharging heat or cold air and costing more in HVAC
@patdrumm3770 yup, this isn’t something I could do if I wanted conditioned air in the shop. I’d also need some kind of makeup air with the volume of air being pushed out of the shop.
Great idea Thanks for sharing
Great video !! TAKE CARE !!!!!
At least you didn't use a Walmart-special square box fan that just recirculates dirty like so many others have done. Kudos for that.
Love this. Very clever design buddy.
That's clever. I like it. I would add a holder on the cart for that cute little spanner that's used for removing the filters. I'd forget where I had put it every time :-) Great content. Thank you.
cool project ! for your measurement, your CFM measure taken with the anemometer on the fan gives you a low number because you are sampling a really low surface area.. Taking your CFM a few feet above should give you a proper result instead of a localized one. (venturi effect plays a big role on fan efficiency)
This was the big issue with me. I wanted him to raise that anometer at least a foot and a half off the fan
Like your video style. Excellent narrative
15:00 I like the pre-filter idea I hope it works out well. Also when you take the tape off it probably won't come off the cardboard very well but if you cut around the edges or next time put a gaffers tape edge on the material and fold it around then tape it onto the filters you should be able to remove the material from the filters pretty easily and reuse it. The edging will give the material some edge strength and then the gaffers tape should release fairly well from itself.
Love it!
Make one that's like a giant bong, where instead of blowing through a filter the air instead bubbles through a bucket of water. And then all the dust will get trapped in the water and there's no filter to change or clean, just dirty water to dump and replace.
You should use your t track system for clamping your pocket joints.
13:13 Oh that's a KeyPoint sure a battery operated fan that's great, but forgot to mention that it's a corded option that's really cool. Because then when the battery dies you can plug it in ( maybe it'll even charge the battery? ) and then you can detach from the wall and move it around again.
Maybe I missed it in the video, but you have to do a calculation for CFM. Ft/min*area. Nice build, and great Idea to make it battery powered/portable.
While the air filter is excellent, it is a failure as a means of removing fine dust from the work area.
Air suction occurs from the floor level to the waist, dust from the machines is above the waist. This fan creates air movement by dispersing dust from machines. More effective would be a flexible hose with a funnel that can be moved as close as possible to the work area where the dust comes from.
@ 1:40 I’d argue that the average Milwaukee “fan” is much larger than 21” in diameter…😂
Then @ 3:59 your sponsored plug would give you a great chance to choose literally any number of corded fans in the marketplace that are likely far stronger and far cheaper for the cfm than the Milwaukee cordless one you chose. Just build a place on the bottom for your Yoshino battery pack to live and run the cord from the fan on top on down to the battery. Still stable and if anything probably more stable as the fan up top is lighter and the base is now quite heavy with the Yoshino.
Plug in overnight and you’re good to go.
Glad I haven't pulled the trigger on the 3D kit yet. Love the battery operated fan and that it works with his parts. Pretty sweet setup my cyber friend! Semi-pro tip for ya...cut off your anamometer lanyard; mine got sucked into the fan and broke. Oops.
Hah, good idea on the lanyard but I'm worried about the entire thing getting sucked into my dust collection hose when I test that in the future! The cordless fan is working great, loving this filter cart so far.
Milwaukie fan and a Dewalt battery - Priceless. Whats the run time with the battery?
Others: Why are you coughing?
You: Battery low.
Hahaha! 😂 It's pretty cool the fan has a corded option too.
Do you have a video showing how you did the pattern on the assembly table?
Awesome work, dude! It really turned out amazing! 😃
But, honestly, I don't even want to know why you have a fog machine... 😂
I want one as well! 😂
Stay safe there with your family! 🖖😊
Why not just build screens that sit on top of the filters? So 1 large screen per 4 sides. With 4 tabs to hold them in place to pop in and out. You could also make screens that hinge like a large door over both screens per side. So you open the screen, clean it off , replace the filters. Close and good to go. Quick & easy.
You kept calling it “cfpm” but what you were measuring was “fpm”. You need to convert it to CUBIC fpm. But either way, still shows a measure an airflow.
Look into deep filters, they cost more but will provide more surface area and more air flow
Will do!
You might have caused yourself a fair bit of extra work by adding the pre-filtters. Essentially you reduced the total surface area available to hold dust before the filter clogs up and restricts airflow significantly. Probably not an issue if you keep up with vacuuming them regularly but I know I would get tired of doing that very quickly.
I had this thought, too.
I mean, it's not terribly different than his existing dust collection system with the paddles inside the filter tubes that knock the dust off to extend the life of the filters. Besides, it's probably like 1 minute worth of work once a week. It's not that big of a deal.
You should make another set of 8 filters ahead of time and squirrel them away somewhere. When it's time to change them, if you have to do a bunch of work, you'll delay it - potentially impacting the air quality. Having a set on hand makes it much easier to just change them as needed.
Probably a good idea!
CFM isn’t enough of a measure, you need to account for volume, but more important for filter. You need to know your fans static air pressure, this fan is likely not strong enough to push efficient air though the filters
Appreciate videos that highlight safety measures in woodworking. Thank you for showing us how you’re prioritizing air quality. When UA-camrs care about safety it’s easier for DIYers to care about safety.
If the mesh catches the dust.. when you turn the fan off and roll the cart away.. what’s stopping the dust shaking off the mesh onto floor.? Like it does on a vibrating filter cleaner on a cyclone.
Nothing. best to keep these stationary.
Enjoyed the video - Thank you. I saw a Harvey Dust Collector in the background. Are you happy with it? Do you have details in any video or videos you're planning to do? Thank you. - Steve
Wonder instead of all the clips keeping the filters in and the pre-filter screening tapped onto the filters, you could make removable panels with some plywood and screening on it. You could use magnets or star knobs to attach the panels on and the screening could also keep filters in their spot. That'd also cover any screws holding the corners together. Use walnut instead of plywood like a real UA-camr :D
Any plans to make the prefilters reusable or at least easily switchable? Probably easy to blow out outside
that was awesome. I have been thinking about doing something like this. My shop is in the basement and too close to the HVAC for the house. I like the idea on the additional mesh too so you can vacuum it from the outside. I would be curious for a long term review on this? like after 1,2,4,8 weeks of use or until you replace the filters, how does your CFM drop or ability to get the particulate level down? Oh, and great idea on the battery adapter! I have all Dewalt stuff, but have been eyeing the Milwaukee cordless 18 guage brad nailer. Tool only is like $260, but with batter and charger its like $400. If for $10 bucks I can use my larger dewalt batteries, that would be awesome!
i dont see the link for the battery adapter. is it missing?
How could you possibly be ok with only 1 filter with its corrugations oriented 90° from the others.
Wanted to see if anyone commented on it 😂
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
i've seen a few of these on youtube, some had the fan blowing into the cart (dust is on the inside) instead of this version where it blows the air out of the cart (dust on the outside). curious if anyone has any reasons why one is better
👍🏾
👍👍👍👍
You don’t have a circle cutter for you palm router?
@ 13:45 Wouldn't the A/C filters affect the CFM?
I don't think you're getting maximum filtration with your design. I recall reading somewhere?? that your filter's fan needs to create a vortex type effect in your shop. This way you are forcing the air around as apposed to waiting for it to come back to the cleaner.
How are you gonna empty the dust? Loving the machine, just a question...
I’ll just vacuum off the pre-filter mesh and eventually change the filters.
Whoever claims that someone else made it, just remember that during the high time of the pandemic, people were making FFP3 (or N100 if you are American) filters for large rooms. It's not some novel design, even household airfilters are using the same design.
Also this particular design, when used in a shop, is a bit stupid, for viruses it's awesome, as they get trapped in the filter (either by brownian motion or electric charge of the fibers), but for the larger particles of dust that stay on top of the surface of the filter, once the fan is off, they will just fall off and become airborn again. You need a way to enclose the dust in, not leave it on the top of the airfilter. There is a reason why household machines have the filter enclosed in another box.
That 1181 ft/mn reading was airspeed, not volume. You want CFM, not ft/mn. You'll need to do a bit more math, or I think the BT-100 has a setting that will calculate CF/M for you, if you enter a couple of variables that you measure independently, first.
how must air do you get in the shop. If you not at must air in, as you will get out, it does not work
Possibly the most over engineered frame I've seen for this, I've seen similar products out of cardboard. That being said yours is awesome! And will definitely last way way longer!
Isn't the fan and the filters the wrong way? this is like bruming the whole room and then dumping the dust in the middle of the room again. Filters don't "hold" particles they prevent them pass through.
💪💪👏👏
7 x 8 = 56. Not 58.
Im planning a similar cart soon.
I bought your plans for the air filter and the only thing that I have received is a picture of it.
It says on the page description it will be delivered may 13th. Maybe you'll get it tomorrow.
Im not sure about air ditection
Every single time you will move it , the dust on filters will get on the floor
Great idea and great build!
I do have to wonder though: I just watched a woodworking project video on UA-cam and you didn't use Rubio Monocoat or Total Boat epoxy... It makes me wonder if you're even a REAL UA-cam woodworker.
lol, watch my most recent video, I used both of those 😂
@@craftedworkshop I just watched the video. Faith restored. 😎
Comperetto cube
The 3D Handyman made it
Yup, I mentioned this multiple times in the video. I designed my cart based on his design but mine is easier to build (IMO) and fits this larger fan and filters.
you may live to regret that thumbnail. Any of those Perkins boys good with Photoshop?
P65, Avoid breathing altogether!
Thanks for showing the build for the 21inch fan
You mean 3D Handyman, who I talked about multiple times in the video? His design was based on an existing air filter and I modified the design to be easier to build and work with this larger fan. I also linked to his Etsy store in the video description.
Pipe down
Where do I buy the filters?
@@craftedworkshopsome people don’t listen or even watch the video or else they would know this already
@@craftedworkshop ok, i'll watch again and if I'm mistaken of course I'll withdraw the comment with apologies
Drag around cords??? Your'e in a shop.
All of my camera gear (tripods, lights) are on casters making extension cords are annoying to roll over. My robovac also gets hung up on them. I try to minimize extension cords and use gaffer’s tape to hold down more permanent cords to reduce trip hazards. I did all of the electrical in the shop and have outlets all over so I can really cut down on cords lying across the floor.
Surface dust is sadly semi unavoidable. Its too heavy to float around for long and get filtered by all but the strongest of filters.
3,299$ for a battery. Nope
