The Dyson Purifier Big+Quiet Formaldehyde is engineered to purify the air in large, open indoor environments with unmatched quietness and efficiency. It combines advanced filtration technologies with innovative airflow mechanics to ensure clean air reaches every corner of a room—up to 100m² in size. Unlike traditional purifiers, it features Cone Aerodynamics that project air up to 10 meters without the use of disruptive, high-speed fans, making it ideal for noise-sensitive spaces like bedrooms, living rooms, offices, and studios.
This model constantly monitors the air quality, detecting ultrafine particles and gases including formaldehyde, and automatically adjusts purification performance accordingly. The integrated LCD screen and app connectivity provide real-time feedback on indoor air quality, temperature, and humidity. Its high-efficiency HEPA H13 filtration system is sealed to capture allergens, pollutants, and viruses, while Dyson’s Selective Catalytic Oxidation (SCO) technology breaks down formaldehyde into water and CO₂—permanently and without needing filter replacement. The result is a purifier that’s not only powerful and intelligent but also low-maintenance and whisper-quiet during operation, blending seamlessly into both home and professional settings.
