Which AC should I buy if outdoor pollution is a concern?

Prioritize a model with PM1.0 filtration specifically (the finer grade — 13 of 78 models have it) over PM2.5, since it captures smaller particles. Beyond filtration, remember an AC filters air only as a byproduct of cooling, not continuously — if pollution is a serious daily concern, pair it with a dedicated air purifier rather than relying on AC filtration alone.

This is genuinely a case where the AC alone probably isn't enough on its own — see our page on AC vs air purifier for the real distinction. Picking the finer PM1.0 filter over PM2.5 where both are otherwise similar is a real, meaningful upgrade for pollution specifically, not just a marketing distinction between the two ratings.
