Have you (or a reviewer) compared their device with a traceable & calibrated device? I’m curious about how accurate it is.
Small thing:
“requiring high-filtration masks” is a broken link.
I don’t have anything calibrated; this device supposedly calibrates itself to outside air ppm?
Fixed link!
Have you measured “outside air” with it?
Yes: stays pretty close to 400
That’s good evidence to have!
