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 you have a large open home and need something you can move between rooms without it driving you crazy with noise, the ProX is the pick — Reddit and WIRED both land on it for the same reasons.
