PM2.5 frequently asked questions
What PM2.5 level is unhealthy?
Thailand's 2023 standard puts the 24-hour average limit at 37.5 µg/m³. Above that, sensitive groups — children, older people, and anyone with heart or lung conditions — should cut back on outdoor activity; above 75, everyone should avoid outdoor exercise and wear an N95 mask.
Why do nearby stations disagree?
PM2.5 depends on local traffic, burning and wind, so stations a few kilometres apart genuinely read differently. The nearest reading is a better basis for a decision than a provincial average.
How often is this updated?
The data comes from Air4Thai (Pollution Control Department), which reports hourly. We fetch the latest values on every visit and cache them for about 10 minutes.
