I’ve never heard of personal Air Quality Detectors. Are they for both indoor and outdoor use? I would love to have such a device on a wristband and be able to constantly know if what I’m breathing isn’t poisonous.
There are some truly personal and portable monitors but the trade off is simplified report—almost Green, Orange, Red—or just one measurement, maybe just PM2.5. Others, as price goes up add in lots of other monitoring. I’ve focused on only particulate matter for the moment. Try a search on Amazon and see the near overwhelming selection of devices.
