About this item

• LARGE COVERAGE: The top-performing Levoit Core 400S Smart Air Purifier can purify large rooms, such as bedrooms, living rooms, kitchens, and basements. Purify a 403 ft² room 5x per hour and a 1980 ft² room 1x per hour
• 3-STAGE FILTRATION: Filtration includes an Efficient MiddleFilter, which traps pollen, dust, and pet dander, and an Efficient Activated Carbon Filter that helps neutralize odors, cooking and wildfire smoke, and VOCs
• WHISPER-LEVEL QUIET: Keep the Core 400S running throughout the night, as Sleep Mode uses the lowest fan speed (24dB) to create a sleep-friendly space that's as quiet as falling leave
• COMBAT ALLERGIES AND ASTHMA: Powerful air purification during allergy and wildfire seasons helps capture allergens that cause sneezing, congestion, breathing difficulties, and other symptoms
• VIEW AIR QUALITY: The laser dust sensor scans the surrounding air for airborne particles, continuously updating the PM2.5 display and creating graphs in the VeSync app so you can see how your air quality has improved
• TRUSTWORTHY AND SAFE: The Core 400S is Energy Star, FCC certified, ETL listed, German Design Award (2021) and iF Design Award (2021). Only use Levoit replacement filters for best results and product performance. AirSight Plus Technology uses a high-sensitivity laser dust sensor to scan your air for allergens. Then, if selected, Auto Mode will adjust the fan speed for you, so you never have to guess what your air needs.
