Air quality in Cabanatuan City right now
Right now the modelled US Air Quality Index for Cabanatuan City, Central Luzon, Philippines is 106, which falls in the "Unhealthy for Sensitive Groups" band (up to 150). People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Cabanatuan City, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 56 µg/m³ in the next 24 hours while NASA satellites detected 3 fire hotspots within 300 km in the last day (nearest about 207 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 106, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
