This is Jay Bates idea, not mine. His blog about it is here: https://jayscustomcreations.com/2016/05/mobile-air-cleaner-cart/I added a few personal touches though. I put the switch down low to be operated by a foot, and so it could be flush mounted. I also found a male 3-prong power adapter so I could just use a whole extension cord without chopping the end off of it. Then I added a reel of sorts to easily store the cord when it needs to be moved around. And lastly a piece of expanded metal sheet to keep curious hands out of the blower fins. Otherwise it's pretty much just Jay's design.Gotta say, thee things really move the air, even on medium or low!I was originally going to make one of these for my shop. I had the filters ready to go and a blower from my old furnace that was just replaced this summer. But I felt since my wife is a teacher and her school is reopening in-person right now, that they could use it more. Further, she's a music teacher and any kind of instruments or singing is inherently higher risk due to the pandemic. They intend to keep making music as safely as possible. So for all these reasons I decided they could use them more than me. I'm instructing them to never run when people are around to avoid making air currents that could increase transmission, and to only run them if they have a period of 1hr or more to be sure it can actually filter the air as opposed to just stirring things up. So between classes if a room is vacant for the hour, or overnight.I had enough filters for 2 so I did some sleuthing and found another furnace blower for free and just built 2. No idea if these will help, but if it helps even one kid or teacher or custodian I'll be happy. With my use recommendations it certainly won't hurt anything.Stay safe everyone! Here's a few more pics of the build.
