What Is PM2.5?
Tiny particles, real health effects
PM2.5 refers to particles smaller than 2.5 micrometers — about 30 times thinner than a human hair. They come from vehicle exhaust, generators, burning waste, and cooking fires, and they're small enough to enter the bloodstream through the lungs. The table below shows what each range means in plain terms.
0–12
µg/m³
Good
Air quality is satisfactory. No health guidance needed.
13–35
µg/m³
Moderate
Sensitive groups (children, elderly, asthma) may notice mild effects.
36–55
µg/m³
Unhealthy for Sensitive Groups
Reduce prolonged outdoor exertion for children, elderly, and those with respiratory conditions.
56+
µg/m³
Unhealthy
Everyone may experience health effects. Limit outdoor activity where possible.
Why it matters here: Respiratory illness linked to air pollution is one of the leading reasons families in Monrovia's dense neighborhoods visit clinics. Knowing today's reading helps you decide whether to keep children indoors, run errands earlier in the day, or use a mask near high-traffic roads.
