DIY corsi-rosenthal boxes are cheaper than commercial air purifiers and easy to assemble with duct tape. (Color/patterns with duct tape add some fun looks.)

High static pressure PC fan boxes are more expensive but quieter, fit more unobtrusively in rooms, and with lights ... look cool.

#CO2 reading of 534 ppm* in my #Brooklyn apartment this AM—one adult (me) and two cats. One window cracked open -2 inches. Not bad!

Note: reading was taken after I’d been rushing around doing household chores (i.e. vacuuming, washing dishes) for 30 minutes, so I suspect I would’ve gotten a lower reading if I’d been sentient.

*Accuracy of CO2 monitor estimated +/- 50 ppm

The past week, #NYC #MTA buses have been consistently packed with maskless people, including many small children with wet coughs. Truly an unfortunate time to have no other options besides public transit 😖
