Editor's Pick: If seasonal allergies make your nose uncomfortable, placing one in your bedroom can really help. Its built-in sensor checks air quality 60 times per minute, and the fan speed automatically increases when indoor smoke or cooking smells get strong. The sleep mode is quiet and won't disturb your rest at night. Ideal for bedrooms, offices, or basement rooms.
