Disclaimer: this is not my design! This is the brilliant brain child of Jim Rosenthal and Richard Corsi, who distributed plans across the interwebs shortly after it became apparent that SARS-CoV-2 was an airborne pathogen. I merely fabricated this box of COVID Christmas cheer to minimize the viral load in our house. After valiantly avoiding COVID-19 all the way until Christmas of 2023, my lovely wife got tagged during (we think) a dental cleaning. She went hardcore Plague Mary as soon as she felt symptoms, masking all day long except to eat and drink, sleeping in a different room. The full deal.

And we ran this bad boy 24 hours a day. Here you see it in our humble utility room. It was too loud to bring out into the main house, but we only have about 1200 square feet, and NOBODY ELSE got sick. They only cost about $100 and maybe an hour of time to build. It’s not a big ask of money or time. So if you find yourself in a similar situation, and want to avoid a house full of sick people, bash one of these together and encourage your infectious loved one to mask as much as they can bear.
