What should I do at home during haze?

Keep windows and doors closed when PM2.5 is above 55 µg/m³, run a HEPA purifier or air-conditioning on recirculate, and avoid frying, incense and candles.

What is PM2.5 and why does it matter?

PM2.5 is airborne particles smaller than 2.5 micrometres, measured in micrograms per cubic metre (µg/m³). They are small enough to be breathed deep into the lungs, and wildfire smoke is rich in them.

Pets in haze: walks, play and indoor air

Above 55 µg/m³ shorten walks and avoid intense play outdoors; above 150 limit outdoor time to toilet breaks. Pets breathe the same air, and small or flat-faced animals may be more sensitive.
