https://www.aliexpress.com/item/32887570197.html $90 PM2.5/ HCHO/TVOC CO2 I have this exact model and it works very well. I keep my apartment window openly constantly whenever I'm home now (though my place is pretty small). I live in a 60m2 cheap apartment and if I keep the place closed, CO2 levels will exceed 800ppm in about two hours just from one person breathing. |
