Having a shop in the basement means I could use the floor joist cavities, so I boxed in a section directly above my main work area (table saw, assembly/sanding table, etc.) about 50x15", created a simple frame to hold a few MERV 13 HVAC filters and used a 8" 450 CFM HVAC duct booster fan mounted to one end and a 8" HVAC pipe to send the clean air to the other side of the shop. Along with an Amazon smart switch, my Alexa air monitor turns it on and off based in the particulate matter is reads. Works like a champ and can clean my shop air in about 15-20 minutes. Easy to vacuum when it builds up and remove the filters to blow them out or replace as needed.
Just started setting up a shop in my basement, and dust collection/noise is a major focus, dust being number 1. I have a 12" negative air fan direct vented to the outside and three shop vacs, one for attaching to the larger saws, a smaller one for attaching to smaller tools and a third for general cleanup and to use on a tool, if needed. This setup really isn't too bad for a start, while still using a P100 filter mask. My next step was to install a Wen filter box...then I read what you have done with your space and this seems like it would be much superior. I have the same exposed structure situation to make use of what you described and even have two booster fans on hand that I haven't installed in two longer runs of a ducted heat pump system, which also use furnace filters. It was meant to be hahaha Thank you for the insight!
FYI the fan laid horazontal like that is bad as the bearings arent designed for that and can be a fire risk. I would build it so the fan was still virtical like its designed to be. Look up box fan fires.
I have an old furnace blower that I built a plywood box around, with a space in the back for a filter. It moves far more air than any of the options you showed.
Best build would be a down draft table for sanding work on. Pegboard surface can accept pins as stops. Screen/cloth at angle below to catch large dust. Slot for quality filter in front of fan, sitting upright under your table aimed at your lower body to keep you cool. Transom or duct fan should have better cfms.
TIP: Lasko and Pelonis make box fans with high CFM and low noise. I built a box like yours for my computer cabinet which contains a dozen servers & networking gear, total cost $40 with a Lasko 20" fan, 1 hour build time. Mine is longer & shallower (the key is Total Surface Area) and it's mounted at the bottom of my cabinet so it draws cooler air off the concrete floor which helps with cooling. My servers aren't even in enclosed cases because they're only exposed to filtered air.
Some good points here. I have a ceiling mounted Jet unit. Have always seen lots of debate about using air filtration systems like this and honestly have never come to a good conclusion myself. Some say that when running the ceiling mounted units *while* you are in the shop, you're just pulling the dust through your breathing area. So some say only run them after you leave. Others say run them the whole time you're in the shop. Obviously running them while you're making the dust prevents the surfaces from becoming dusty, but dust on surfaces isn't dangerous until it becomes airborne. Wondering where you stand on this debate?
Damn buddy ! When you are cutting on that table saw or building that air filter box you are quick ! On my jobsite I've never seen anyone move that fast. 😀👍
Bladed fans will draw more Amp as their air flow is blocked off. A squirrel cage fan is what you'd want to use when their is going to be any back pressure, as they will not draw high amperage when the air way is blocked.
Hey man, i was about to do this - I have the tape and the filter... However I noticed my box fan has a the power cord right in the middle of the back of the fan. Should I A. Proceed and make a hole in the filter to fit the cord? B. Put the filter in the front of the fan or C. Get a new fan to do this with??
Using a furnace filter on a box fan does do a great job of cleaning the dust particles out of the air in your shop........IF..........you're using the right filter. The average run of the mill furnace filter isn't really capable of collecting fine sawdust. If you want this to work properly, you need to use MERV13 rated furnace filters. Yes, they cost quite a bit more than common filters, Amazon has the best price I have been able to find, and if you buy a box filters, they cost even less. Don't think you can get away with running a MERV 13 filter in your furnace, unless it is rated for that filter. My 80% efficient furnace would live a pretty short life if I tried using those filters. Even buying MERV 13 filters, you're still at a very small fraction of the price of one of those, commercially made "air cleaners".
Makes me wonder if something like this could be built as a portable "kitchen exhaust" system (aka smoke catcher).. It might work, but... not as effective??? I would imagine smoke particles are much smaller than dust? Here is more expensive but quicker to build system ua-cam.com/video/rOecQZZR5kA/v-deo.html
I made a three stage one with 3 box fans and three levels of filters. Made a huge difference in air quality.
That sounds pretty slick!

Shear genius! I’m going to make this system in my basement. Thanks

Thank you. The honesty of this video in under 2 minutes earned a sub.

You convinced me, to just put a double door in the back of my garage, and just roll out my power cutting tools outdoors when cutting stuff.

What if you run both filter set ups at the same time!?

Just found your sight and super impressed-subscribed! Thanks a bunch!
Awesome to hear! Thank u🍻
Nice garage 👍🏼
Did you expand your shop? or put up a new shop building? It looks bigger than your garage from earlier videos...
Serious upgrade in the shop, dude.

I’m AI😂🍻

Woah, when did he get a new shop?
Just did a big move, the new shop was a nice bonus!
@@TheFunnyCarpenter shop tour soon please and thank you.
thank you!
I see you linked Merv 11 filters, would anything above 11 provide better filtration for this purpose? They seem to get really expensive after 11 ha.
I think Marv 11 is a sweet spot, or even the Merv 8 filters I used in the video.
@@TheFunnyCarpenter Thanks for the info! & everything else you do. You're a cool dude 👊
How long do the filters last?
Is there any advantage to adding a filter to the back of the free standing fan as well as the front?
Great Video!
Thanks buddy🍻
Thanks.
👍👍👍Thank you.
Awesome tips ! Thanks !

I think you could probably make it work, just by running the cord along the fan and out through the corner and then just seal it up with the tape.
Dude, make a decision and go with it.
@@TheFunnyCarpenter Awesome will do, thanks!

New shop?
I’ve made it out of the garage!

Anyone have a link to the best build video?
⭐⭐⭐⭐⭐
Thanks
But if you grow your mustache super bushy over the lips and fluffed up in front of your nose, you have a filter already
Hard to beat a merv 13 moustache😂

yah i never liked that i spent $300 on an air cleaner that's basically just a furnace filter and a centrifugal fan in an overpriced metal box
Hee haw chee chaw
Forget this "partner" crap it's wife (female) or husband (male).
Meh, there’s different reasons people call people partners. All in all it’s good term in my opinion.
Is there nowhere we can go to escape right/left culture wars? Give a rest, fella.
@@TheFunnyCarpenter Agreed.....
Instead of three stages, I have three stooges
