Air pollution level in Manila is fairly low

Manila's air quality is actually pretty good overall
When you look at where how it ranks in air pollution (source: https://www.airvisual.com), it's actually cleaner than cities like Paris, Hong Kong, Singapore, Bangkok, Milan, Chiang Mai, Jakarta, etc.
It's comparable to Tokyo and Los Angeles, and slightly worse than Singapore
The cleanest months in the year are June and July, but the even the rest of the year aren't that bad
No need to bring masks or anything like that
The only times you need to worry about air pollution is if the haze from Indonesia drifts over during their burning season. Always a good idea to check realtime AQI (from sites like https://air-quality.com) before you visit
