Awair had a $100 coupon going on Amazon recently, I think there was quite a bit of trouble when the company (or part of it) invested too heavily in a crypto project that went sideways. Not sure what the status is there (see Twitter).

That aside, I LOVED the Awair. There's a great story by DHH online on how his entire family got into somewhat serious health trouble due to heavy VOC exposure, and the Awair basically revealed all of it (I think it was an interview on YouTube).

Just be aware that the cheaper devices use cheap sensors to estimate certain measurements and aren't as reliable. There's some on Ali Express you can buy and wire up yourself (or use HomeAssistant with it). I prefered the Awair due to its neat look.
