Breathe cleaner air with the Honeywell Allergen Plus AQSense™ HEPA Air Purifier, an effective choice among HEPA air purifiers for bedrooms, living rooms, and more to support home comfort for homeowners and pet owners. This compact air purifier features a 360° 3-in-1 HEPA filtration system that provides effective air purification and indoor air quality improvement by helping capture up to 99.97% of microscopic allergens such as dust, pollen, pet dander, and smoke, including wildfire smoke. The carbon filter helps reduce odors from pets, cooking, and household products, and also adsorbs VOC fumes, while the vacuumable pre-filter traps larger particles like hair and lint. Equipped with AQSense™ Auto Mode, it uses a built-in air quality sensor to monitor and adjust fan speed automatically. The color-coded air quality indicator displays air quality. Ideal as a nursery or bedroom air purifier, Sleep Mode ensures ultra-quiet operation with dimmable lights for a peaceful nighttime rest. AHAM certified, this tabletop air purifier circulates and filters room air 4.8x per hour in rooms up to 110 sq. ft. and 1x per hour in 530 sq. ft. rooms. With three cleaning levels, timer settings, and a filter change indicator, it's easy to maintain a cleaner, fresher home.
