DM-69 Air Quality Monitor 8 In 1 for CO2, PM2.5, PM10, TVOC, HCHO, AQI, Temp and Humidity
Spring Sales 2023
This has nice form factor. The screen is very easy to read. It looks nice whether it is sitting in your living room or in an out-of-the-way area.
I did have a power supply problem, but the seller reached out to me and quickly resolved my issue. (I'm very impressed with their service and support!) One important point is that it turns off after 11 hours in order to save battery power. Even if you have it plugged in to a power supply all the time.
I got this mostly to check the dust / particulates in the air since my spouse is very sensitive to dust. I'm very pleased with this company and this air quality monitor.
