I slapped together this panel true CRBox style next to my bed, a 200mm fan and a 10x10 filter, with chopsticks for a riser between them and black washy tape. It’s silent and been running maybe 1.5 months. Check how nasty the filter is! So glad that’s not in my lungs!

New #CRBox vs one made Jan 2022.
Is it time to change the filters on your #CorsiRosenthalBox? Try the tissue test. The art room at my kid’s school has clay spinning wheels so I anticipated they’d need a more frequent filter change. With the fan on level 3 it still can’t grab the tissue. Changing filters today.

Inspired by @JimRosenthal4's recent post, I wanted to build a CRbox for my car (temps ↘️ in MN so 🚘 🪟 closed). 15-min build w/ two 12x12x1 Merv13 filters + AC Infinity S7 airplate (5V USB) + 12" self-stick tile (for stability). Total ~ $60, ~104 CFM.
