HOW TO READ YOUR AIR QUALITY MONITOR
Happi’s air quality monitor measures the level of PM2.5 present in your air. PM2.5
stands for Particulate Matter 2.5, or tiny particles that are ≤2.5 microns in width.
Studies have shown that exposure to high levels of PM2.5 can cause respiratory
problems in addition to aggravating existing health issues.
