What matters most in an air purifier for allergies?
Filtration quality, realistic room coverage, and a purifier you will actually run consistently are usually more important than extra smart features.
Is a bigger purifier always better for allergies?
Not always. Matching purifier size to the room where symptoms are worst is often more useful than simply buying the largest model.
