Nice video, I’ve always found these interesting and I’m thinking about buying a few for my house. It’s an extra layer of precaution that’s probably worth the cost. I’m always on people about washing their hands, It’s simple and effective yet people don’t do it most of the time.
I have 4 Honeywell Hepa filters in my house do to pets and my wife allergies. The Honeywell one are really nice and work very well, the Hepa filters last a year and the pre-filter last 2-3 months depending on the dogs shedding. Im not worried about a virus, but a happy wife keeps me out a trouble just little bit longer.
