It's one of those things quite interesting to see the difference in response from one consumer to another. I can't stand the washer/dryer notifications and finally turned them off a few weeks ago. Especially when I'm on the road half the time, why should I care my wife did 8 loads of laundry in a day? When I'm home, the chime is enough to hear from the other room anyway and the notification on the phone usually just backlogs and gives me a load of red badges I need to clear at the end and beginning of every day for notifications I didn't even get because the phone wasn't with me and I changed the laundry anyway.

For an air purifier, I feel like I'd probably want to see outcome-level statistics convincing me it actually matters to lifespan, healthspan, quality of life, something, anything at all, to know and adjust minute-by-minute the exact air quality going through a purifier, or for that matter what the purifier is able to detect even reflects the quality of air elsewhere in a house with a whole lot of air volume not going through that purifier very regularly.
