DIY Shop Air Filter (from a furnace blower) 

That jig saw is a beast. I was just thinking about doing something like this and wanted to watch someone else think through the process first, thanks for posting your project. I am thinking about asking some local hvac contractors if they could save a blower from a used furnace they are throwing away, or the whole furnace so I can cut the blower assembly out myself. We will see how that goes.

Cool! I was just commenting about my lack of air filtration.

Nice project.

I don't have oddball parts like a blower hanging around, but what I did for a bench top air cleaner was use one of those cheap box fans, and then tape a 20"x20" furnace filter on the "inlet" side. Works great when placed close to my projects as I'm sanding. Vacuum the filter a few times, then eventually replace it. Cheap, easy, and I'm going to make a few more to just hang from the ceiling.

This project just sucks...then it blows... like you weren't expecting someone to post like that in the comments... lol Nice project. It beats my square box fan with two filters wire tied to it. Thanks for the video, Jeff! Thumbs up for sure.

Nice job!

Nice build Jeff. I particularly like the corner door to access the filter. Trying to pinch the end of a dirty filter by the end through a thin slot is a pain. Because the filter is so close to the circular intake port, I wonder if you find the filter loading up more over the circular opening? A larger space between the filter and the smaller port might allow the air to be pulled better through the larger surface of the filter.

I had thought about this myself, looks really good

Hi. Just discovered your channel. Just the kind of stuff I LOVE to watch because I also LOVE to fix things myself. Aso, I love the deleted scenes at the end, it will make me laugh in the future when working on my projects and something funny happens rather than going like ''rrrr***&$"&''... LoL. I also have 2 young kids myself (single daddy here), so every time I'm watching a video and I hear or see a young kid showing up , it always put a big smile on my face:):):) !!! New subscriber here for sure!!! When I discover a channel like yours, I always feel like a kid walking in a candy store :). Tks.

Just got one .... i have a green "ground" wire along with the white / black wires ... should i struip the end and bolt it into the metal housing of the fan ? (safe)

Great work

Oh, yeah, I can understand the feeling of mismatched colors as well as other things that most people think nothing about.

Very good job bro

Great video. How did you mount it when complete?

good video Jeff. I have been following along on Instagram with this build and was curious how it was going to turn out. Great job and you have inspired me to do a very similar build.

Great idea great video thanks for posting this. I would think it works so good you will be changing the filter regularly. Might have been better with a readily available (read as cheap) filter.

Nicely done looks great!!

I think that is the largest jigsaw I've ever seen.

Hi Jeff 👏👏👏👏

Sir can u tell abt this blower specifications

Nice job well done I started to laugh you reminded me the way I am myself with the on and off switch cover I'm the same way great job. question can you please tell me what kind of Jigsaw you use the brand and the model number please thank you keep up the good work I enjoy your videos

Where would I be able to find an old furnace blower like the one in your video? All the ones I see online are “too nice/new”... and expensive 😬

Cool! Looks a little bit like a microwave oven :-)

Lol the RU-vid caption generator thinks your grinder sounds like music.
