I’ve been soaking in all sorts of great advice here, I want to try and contribute something that may be new to y’all.
I read an article a while ago about an engineer who came up with a cheap way for people in China to purify the air in their homes. A box fan with a furnace filter taped to it.
I’ve been running these two for a while, I’ve probably changed the filters 4 or 5 times. This last time was the longest I’d ever gone. So long I forgot what color they were supposed to be. These are definitely helping with the dust in the garage (shop). While I think it’s best to still wear a mask, or use something that actually vents, I think these are still a benefit. Especially with how cheap you can set them up for.
*Edit, I haven’t googled this setup in while, there’s a lot of info on it now. I plan on cleaning up my configuration, but I’m still working on my garage remodel for all the big stuff I need to find a way to store.
