Our take
When expert lab testing and real-world allergy use cases align on the same product, pay attention — the Blueair 311i Max is CNET's #1 pick for good reason and handles pollen especially well.
If the Coway is sold out or you want something with a bit more airflow punch, the Winix 5500-2 is what Reddit's allergy sufferers actually swear by — and that real-world track record matters.
