Air quality

Measure air quality in your own environment.

Indoors

Too high air humidity can cause mold. If the humidity is too low, you will get a dry throat and you may have to cough more often. Exhaled air contains CO2. Too much CO2 in the air is unhealthy. Know the conditions of your indoor climate for a better quality of health .
Outdoors

What is the quality of the air in your area outdoors? Is there much or little particulate matter in the air? We all want healthy fresh air. With a particulate matter sensor you know where you stand.
