Which particulate detector do you use?

[@williamriven]

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).

[@mygamertag2010X]

Agreed. Definitely worth reuploading a revised video that doesn't include referring to f/m as cf/m when using the tester.

[@chaseweeks2708]

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.

[@aloha13randonnn]

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

[@chaseweeks2708]

@@aloha13randonnn an indicator of change, yes, but not an indicator of value.

[@therick0996]

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

[@The3DHandyman]

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!

[@glennryzebol4472]

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!

[@passy707]

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.

[@Lamefoureyes]

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.

[@GardenreetLighting]

Your video was both informative and entertaining! 👍 I loved watching the project come together, and I learned so much along the way.

[@Scottsideways]

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

[@chaseweeks2708]

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.

[@ronlovell5374]

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.

[@davec8141]

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.

[@1320crusier]

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.

[@patdrumm3770]

Yeah but then you end up discharging heat or cold air and costing more in HVAC

[@craftedworkshop]

@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.

[@Stillworks]

Love this. Very clever design buddy.

[@jay-in-az]

Like your video style. Excellent narrative

[@Braddy_Daddy]

Definitely making this!

[@JustinBsDentureJourney]

Really cool project for a fair price. Really enjoyed the vid. Well done as always

[@ronobst4810]

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.

[@Gazman299]

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.

[@jesseelovaas]

Awesome idea!

[@chasesmith7620]

You should use your t track system for clamping your pocket joints.

[@jimrosson6702]

Great idea Thanks for sharing

[@marymigliore3396]

Great video !! TAKE CARE !!!!!

[@subramaniamchandrasekar1397]

Others: Why are you coughing? You: Battery low.

[@rangerbaynworkshop]

Hahaha! 😂 It's pretty cool the fan has a corded option too.

[@SpaceShrimp]

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)

[@MinorLG]

This was the big issue with me. I wanted him to raise that anometer at least a foot and a half off the fan

[@GlassImpressions]

Love it!

[@joesmucker8012]

Milwaukie fan and a Dewalt battery - Priceless. Whats the run time with the battery?

[@sabregunner1]

i dont see the link for the battery adapter. is it missing?

[@MCsCreations]

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! 🖖😊

[@andyknappenberger7512]

How could you possibly be ok with only 1 filter with its corrugations oriented 90° from the others.

[@craftedworkshop]

Wanted to see if anyone commented on it 😂

[@M_Fitz]

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.

[@iamspeare]

Any plans to make the prefilters reusable or at least easily switchable? Probably easy to blow out outside

[@jmert_5859]

@ 13:45 Wouldn't the A/C filters affect the CFM?

[@Trainwreck1123]

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.

[@sisyphushappyband]

I had this thought, too.

[@chaseweeks2708]

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.

[@mitchellsimoens]

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 KZbinr :D

[@jesperhedegaard-ulstrup6994]

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

[@mariushegli]

I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.

[@The1stKukuDrifter]

You don’t have a circle cutter for you palm router?

[@kgdmen]

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.

[@sawdust85222]

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.

[@GillySqueeze]

The 3D Handyman made it

[@craftedworkshop]

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.

[@IlfStoyanov]

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.

[@tereg5]

Appreciate videos that highlight safety measures in woodworking. Thank you for showing us how you’re prioritizing air quality. When KZbinrs care about safety it’s easier for DIYers to care about safety.

Im not sure about air ditection Every single time you will move it , the dust on filters will get on the floor

[@apollo3604]

7 x 8 = 56. Not 58. Im planning a similar cart soon.

[@se7515]

you may live to regret that thumbnail. Any of those Perkins boys good with Photoshop?

[@andyheilmann1656]

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!

[@leifhietala8074]

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.

[@jondurr]

P65, Avoid breathing altogether!

[@tptwk]

Drag around cords??? Your'e in a shop.

[@craftedworkshop]

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.

[@TheJttv]

Surface dust is sadly semi unavoidable. Its too heavy to float around for long and get filtered by all but the strongest of filters.

[@saljablo2767]

Well this is an air filter which focuses on the particulates in the air so you don’t breath it in. The heavy surface stuff can stay where it is as long as it isn’t in your lungs.

[@VanlifeReality]

3,299$ for a battery. Nope

[@petrann280]

Thanks for showing the build for the 21inch fan

[@saljablo2767]

You could’ve at least mentioned whose idea it was in your comment.

[@craftedworkshop]

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.
