The EASIEST DIY Air Filter of All Time || Build Your Own Air Filter || Woodworking Filtration System

Thanks for the idea and sharing. I've been back and forth on the box with multiple HVAC filters or buying a brand name shop filter, but I didn't want to design and make a box, and the brand names don't filter as well as a MERV 15 filter will. I've give this a try, this will be my first shop air filter anyway. I'm also going to add an inline blower to my shop window to turn on and blow dust out into the woods on days I don't care about AC.

You think it would work better with a centrifugal type blower? I'm thinking so as in you would get more CFM as a centrifugal blower is designed to work under pressure while a regular blade style fan is not meant to be used under suction and loose efficiency quickly.

Genius.

Turning my fan other way. Dog hair and dander are heck on motors. My grandfather used something like this in his wood shop in the 70s. When he remodeled their house every year he brought them in the room he was working on. My grand had OCD about dust. She deep cleaned 18 hours a day. You would never of known my grand had just moved the kitchen to the other side of the house.
Now he even made /ceiling lights/fans that looked like car carburetors. Took box fan and put 4 filters in a box shape for dog hair in the basement walkout area.
I really enjoyed this video. And I smiled at the blower. Again reminded me of my grandfather having to use one before bringing wood inside. I've never seen a wood shop as clean as his since. Lol

Does anyone know of a good UK alternative to Wynn?

Nice, but that seems really expensive when you add up the cost of the filter and fan. A box fan with a furnace filter taped on works just fine. This is too fancy.

Yeah buddy! A little pricey but you get what you pay for. I bet it worked as well If not better than the 1000 dollar unit

It would be cool to have the duel open-ended version of the filter and attach a bucket on one end to catch the dust. Make it last a little longer between clean outs

So n w that you have this a while, how is it working?

Hi Matt, I have a quick question: For a basement workshop with 8 foot ceilings, would you recommend the Wynn/Cat Combo, the JET AFS-1000B, a ceiling hanging dust collector connected to a Wynn Merv 15, a Harbor Freight 2HP with the Wynn Merv 15 filter? My main goal is to filter ambient air. I have shop vacs already attached to my bandsaw, table saw, and mitre saw. Please give me your opinion when you get a chance.

i built a filter basically exactly the same as this but i found there was too much back pressure from the filter and that the fan couldnt push all of its airflow through

I created my own after watching your video. I’m planning to use mine in the house 24 7. I was considering using the lowest fan speed setting because of the blow back and I didn’t want it to overheat. Am I being overly conservative? Anyone have any experience running it 24 7?

Hi Matt, Thank you for posting this extremely helpful and innovative video. I have a question. Do you find that particulates eccesively accumulate and the inside bottom of the filter, limiting its effectiveness, or perhaps requiring frequent cleaning? Would it be useful to cut out a hole on the bottom of the filter and add a bucket underneath via a Gamma Seal Lid? Portability can still be achieved by resting the bottom outer lip of the filter on a small wooden frame, with a circle cut to accommodate the suspended bucket, and with wheels on the bottom. The bucket would just be suspended inside the frame and over the wood base. If it had a little clear plastic window, one could see the collection amount and be prompted to cleaning. I ordered the Wynn filter you suggested along with the CAT fan. I now just have to order the Gamma Seal Lid and bucket. I think this entire set up is outstanding, and should be in every shop. In addition to this, I will still of course have my table saw, band saw, and mitre saw attached to my powerful shop vacs for the larger particulates. Thanks again.

Which model Wynn filter did you use? There are a lot of merv 15 filters on their side categorized across everything from woodworking filters and ambient filters

Great Idea! Simple, effective, not time consuming to construct. Perfect for me and my shop! Thanks!

looks reliable

Great video! My wife had 5 dogs that keep our house covered in dirt/dust, so we have to dust all the freaking time just to keep our house decent and I’m not a clean freak. I’m wondering if a few of these scattered though the house running on timers for when we’re gone would cut down on the constant dusting we’re doing. I know there’s air filtration systems available, but most of them are greatly overpriced and suck.

Finally a simpler mousetrap! 1 fan, 1 filter, and easily serviced. Question: I plan on hanging mine overhead/horizontal...should I double up on the hose-clamps? There will also be a simple belt/hammock support at the filter's end. Thanks!

I just completed the purchase and assembly of the air filter and fan. The casters were mounted to the base using your suggestion. I used 80mm magnets I bought from Harbor Freight to attach them to the metal bottom. Works great! Thank you!

What if you have a 9×12 wood shop. Mine is tiny, and the doors are usually open. Of course, it's summer though.

Good job like $400 bucks on the low end looking for something to purify my home air from pollutants 800sqft

200sqhow long does that filter last and would it be better to just buy a bag of charcoal and make a filter with just the charcoal minus the pre built filter ?

easy to make and use is not the problem, big issue here is that it is extreemly inefective, this would let you just feel safe and encourag you to rust the filter is enough, also it should pull the air trough the filter and not into it, aside that the filter is merv 15 which is way worse then even an HEPA E10 filter on the MERV scale HEPA E10 is a MERV 17 aside from that you would be better off just leaving the door open and using the FAN / BLOWER on its own to blow the dus away from you and it would just be way more efectively and keep your air "CLEANer", SO ALL IN ALL ITS A BIG WASTE OF MONEY

All parts have been ordered. Where do you suggest the unit be placed in a garage...a corner or next to the sawdust-producing tool? Again, thanks for the great idea.

common sense simple nice

In a word: Genius. Thank you so much.

How loud is it? in db?

I was going to tape an air filter to a box fan, but might try this.

I'm not sure of the micron rating but I did something similar with semi truck filters.

You’ll clog the filter fast if you blow dust into it… but if you draw air through it, you can wrap the canister with a foam or fabric pre-filter wrap to catch the coarse particles and leave the fines to the merv-15. It’ll cost a lot less to vacuum or replace the foam a couple times than the merv-15. If you want to suck a lot more air through it, use a two fan stack, run at medium speed instead of high, more air, less noise, for not much more electricity.

I built something similar with 20”x30” 3M furnace filters, packaging tape, some cardboard and common 20” box fans to deal with man cave dust and all too frequent wildfire smoke. I double layer the filter panels, 3M 2800 on the inside, and a coarser “odor control” 1200 (charcoal impregnated) on the outside, which only being taped together as one are easy to cut off the outer ones and replace when they get too dirty or dusty to look at.
My first iteration used four merv-12 panels, one fan, it’s least expensive but still taken three years (non-smoker living alone) and quite a bit of fire smoke for me to want/need to replace them.

Thanks for your video ... sorrry in Italy I can't find your filter and the fan but I'm looking for similar objects .... here bye

You're telling me that this filter is also reusable? I am definitely doing this

Have you checked how many decibels it is on high?

Oh , my god. I thought the title said DIY Air Fryer. I instaclicked 😂😂😂😂

Dude, the Comparetto is such a simple design! I am not sure how you claim to want to do something faster? You might spend some time in the beginning that you are making a specific type of filtration system for woodworking, then what I say below would make sense. Still, though, you should shout out Comparetto! We just want to DIY.

What do you mean by frame and housing? The original is only with duct tape! No frame!

You are the one that supercharged it! Special fan? Special hardware? Wheels?! I mean, cool setup!! It's just not "fast" like you said at the beginning of the video. XD

I'm just saying that the original Comparetto Cube is duct tape and a cheap ass fan. Which you can make for under $100, whereas yours is 3-5x that. And if one would plan a little they could use whatever filter their home system does in an effort to not buy different types (if that is a possibility with the system's filters). My Comparetto Cube uses the same filters my house does!

The Comparetto Cube can really help people that might not have any options financially to spend $300+ on an awesome system. With air quality on the decline due to climate change and forest fires, the Comparetto Cube can actually save lives for under $100. I'd pay credit to Comparetto if I were you.

And you have a partial meter thingy?! Cool! I'd like to see a comparison between the Original Comparetto design and yours rather than look at magnetic wheels TBH. I'd increase the Comparetto design's filter thickness to 2" or 4" for a little more longevity for the money). Take the readings with your fancy tool! :) :)

Do you think the flow direction matters? I understand that many would want to have a fan blowing out on a cool day, though I am wondering if mount the fan to blow INTO the cube so the fan isn't blowing papers or whatever is hanging out. You could have it at full speed and not cause any air disturbance.

Perfect for drywall work during sanding.

Very well thought out. Thanks for sharing!

Simple, efficient, elegant.

You need to void getting the larger particles in your filter. Maybe a wireframe on top with a bag inside a bag?

Too save some money, google semi air filter. It’s like $50 instead of 250…

Granted youll need to do a bit of leg work and find the right size

Reverse the fan and place the whole unit in a garbage can .Most air filters are made to pull air in from the outside.Your filter may be different for your extraction unit . BUT a great idea..

This would have been awesome to have during the smoke storms here in New York.

I needed this video about 5 years ago when I built my woodshop. Great video, no excessive talking, straight to the instruction and good pace of speech to action. Can't stand slow talking who drag out their videos to make them 15 minutes or longer.

I love the idea. But what's the reusability of the filter? If I'm reading this all right they're about $225-$270.

Built this bastard 5 months ago. Amazing creation. I have a full gym in the basement and can't believe how well this works. I've noticed dust upstairs has also decreased significantly. I keep it on most of the time and just burnt up the fan. Just ordered a new one. Definitely worth it. Thank you for the video! Brilliant design!

Amazing build and great recommendation! With the air quality issues right now I’m biting the bullet and building two of these. I wonder if you soon get a bunch of view traffic and there’s a run on these supplies.
