Indoor air quality is sometimes worse than the air quality outdoors, however,

we now stay indoors more than ever before!

Monitor the level of carbon dioxide, temperature, as well as humidity 24/7 in real-time!

LED shows you the air quality right after a wave in front of the device.

You can now define your own comfortable environ-ment using

an easily managing app and the Merrylot Air Quality CO2 monitor!
