Key Features That Stand Out

• Compact, Stylish & Energy Efficient: With a sleek tabletop design, this HEPA air purifier is perfect for small spaces like dorm rooms, apartments, and offices. It’s also ENERGY STAR certified, meaning it operates with low energy consumption, saving you money on electricity bills.
• Whisper Quiet for Bedrooms & Nurseries: The dedicated Sleep Mode operates at an impressively low 20.81 dBA, featuring dimmable lights and reduced sound. This makes it an ideal small air purifier for bedrooms, ensuring undisturbed rest and relaxation.
• Powerful HEPA 3-in-1 Filtration System: This air purifier employs a robust 360° filtration system. It includes a True HEPA filter that captures up to 99.97% of microscopic allergens, such as dust, pollen, and pet dander. An activated carbon filter effectively combats odors and VOCs, while a pre-filter captures larger particles like pet hair.
• Certified Performance You Can Trust: The AHAM Verifide performance ensures this mini air purifier circulates and filters room air efficiently. It can filter room air up to 4.8 times per hour in 110 sq. ft. rooms and once per hour in rooms up to 530 sq. ft.
