Based on the most excellent review from Nate Adams, I purchased a FooBot last week. So far its been a blast to play with.
The set up was a bit finicky, but its off and running. The first few days, I had the unit in my kitchen and the general air quality was great. VOC's < 100 PPB, Particulates under 12 ug/M3 and CO2 averaging around 450 PPM. Of course the back door was open most of the time.
Then I took it to the bedroom. Around bedtime (10 PM), the picture changed a bit. CO2 elevate to 500-600 PPM, particulates are off the screen at 130-150 uG/M3. Can't put my finger on it. We do run a ceiling fan over the bed, so perhaps that's linked. Still don't know the source, although I've been told that I snore.
We start the day around 5:45. While my lovely wife (of 40+ years) gets ready for work, I fix the coffee and the oatmeal downstairs. She's upstairs in master bath farding et al. (Look it up, its not what you think)
CO2 jumps to 1500-2000 PPM and particulates stay high. The data log shows exactly when the hairspray comes out. VOC's over 600 PPB. So I have laid down the law, all hairspray must be applied outdoors. Her response, "sure."
My biggest confusion is the high particulates at night while snoring and secondly, high CO2 when she's getting ready for work. I looked at the ingredients in the hairspray and its got 8 or 10 chemicals I cannot pronounce, but no mention of CO2.
