About a month ago, I bought a box fan and an HVAC filter, and set it up next to the #catbox in my apartment. Just one filter taped to the intake side of the fan—nothing fancy like the Corsi-Rosenthal box.

It's super effective! 🎉 The shortness of breath I was suffering from is gone.

#Cat #litter #dust is bad news, people! You need to either vent it outside or filter it like this. Your lungs will thank you!
