Definitely seen these studies. I think they are from a few years back though, so the relevance might be in question. I don't think the newer versions of laseregg, netatmo, awair, or any of the other leading brands are on there. What I love about that study (and find funny) are the A-F ratings. If you look at the averages... both foobot and awair have the same grades (2 As, 2 Bs, and a D), yet one of them gets an A and other gets a C.
For everything non-Radon, I'd trust Awair (http://getawair.com) honestly. I feel like I'm shilling for them at this point. Outside of DHH's recommendation, I read somewhere that their sensors are certified (plus their 2nd Edition does PM2.5 and CO2, unlike the foobot one). I've looked into smart things, but I'm not concerned about Radon, so wasn't going to pay the extra $75.
It took me a while, but I eventually ended up getting a indoor air quality monitor. I'm in California, and when the fires happened, I expected my brand new condo building to have decent filtration. According to my Awair monitor (http://getawair.com)... my indoor PM2.5 (Fine Dust) went up to 150 ugm3. 150! We definitely had a chat with the building after that.
But yeah, cooking, cleaning, air fresheners... all of them negatively affect my home air quality. Just need to ventilate at the right times. After the DHH video about this topic, I pulled the trigger and got the monitor, which fortunately also tracks CO2 and chemical (VOCs).
I'm glad to see 2 topics about air quality trending today. I had to finally register to get in on the one topic I actually know about.
