Breathe cleaner air with the Honeywell Allergen Plus AQSense™ HEPA Air Purifier, a powerful large room air purifier for bedrooms, living rooms, and other large, high-traffic spaces. Its 360° 4‑in‑1 HEPA filtration system captures up to 99.97% of microscopic allergens such as dust, pollen, pet dander, and smoke (including wildfire smoke), making it an ideal air purifier for homes with pets. An activated carbon filter helps reduce odors and VOCs, while the vacuumable pre‑filter traps larger particles like hair and lint. It also includes a fourth filtration layer for enhanced air‑cleaning, delivering an extra level of protection. AQSense™ Auto Mode uses a built‑in air quality sensor to monitor indoor air and automatically adjust fan speed. A color‑coded indicator gives real-time air quality updates. Designed for convenience, this Honeywell air purifier includes a one‑click LessMess™ filter‑change mechanism, a carry handle for easy portability, and ultra-quiet Sleep Mode for bedrooms. AHAM certified, it circulates and filters air up to 4.8 times per hour in rooms up to 354 sq. ft., making it a smart choice for home air purifiers. With four cleaning levels, timer settings, child lock, sleep mode, and a filter‑change indicator, it helps maintain a cleaner, fresher home every day. Disclaimers: * From the air that passes through the filter, 0.3 microns and larger. ** Based on 3rd party independent CADR testing for the smoke CADR value when operated at the highest level. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.
