Dyson Purifier Big+Quiet Formaldehyde BP04 (Prussian Blue/Gold) – Advanced Air Purification for Large Spaces

The Dyson Purifier Big+Quiet Formaldehyde BP04 is engineered to provide powerful and efficient air purification while operating at reduced noise levels. Designed for large spaces, this advanced air purifier effectively removes airborne pollutants, allergens, and harmful gases, including formaldehyde, nitrogen dioxide (NO₂), and carbon dioxide (CO₂). Its innovative three-stage filtration system, which includes a HEPA H13-grade filter, K-Carbon filter, and Selective Catalytic Oxidization technology, ensures a cleaner and healthier indoor environment. The purifier also delivers over 21 gallons of purified air per second, maintaining optimal air quality while offering a cooling effect when needed.

With real-time air quality monitoring and an array of integrated sensors, the Dyson Purifier Big+Quiet BP04 continuously analyzes air conditions and adjusts its purification settings accordingly. The solid-state formaldehyde sensor is designed for lifetime precision, detecting particles 500 times smaller than 0.1 microns. A dedicated NO₂ sensor identifies pollutants from sources such as cooking fumes, car exhaust, and gas appliances, while the CO₂ sensor alerts users when ventilation is required. These features, combined with app connectivity via MyDyson™, enable remote control, scheduling, and air quality tracking for enhanced convenience and efficiency.

Key Features:

• Advanced Filtration System – HEPA H13-grade filter, K-Carbon filter, and Selective Catalytic Oxidization work together to capture 99.97% of microscopic particles, remove harmful gases, and eliminate formaldehyde.
• Ultra-Quiet Operation – Acoustically engineered for reduced noise output, operating 50% quieter even at full power. The Night Mode function provides silent purification while ensuring undisturbed sleep.
• High Airflow Projection – Capable of delivering purified air across large spaces with an adjustable oscillation angle of up to 50 degrees. The Breeze Mode mimics the sensation of fresh outdoor air.
• Real-Time Air Quality Monitoring – Integrated sensors detect and analyze pollutants, including NO₂, CO₂, particulate matter (PM), and formaldehyde, adjusting purification settings automatically.
• Long-Lasting HEPA Filter – The durable HEPA H13-grade filter provides up to 11 years of efficient performance with a simple one-click replacement mechanism.
