Dyson Purifier Big+Quiet Formaldehyde BP04 (Prussian Blue/Gold)

The Dyson Purifier Big+Quiet Formaldehyde BP04 is Dyson’s largest, quietest, and most powerful air purification system, engineered specifically for large living rooms, open-concept residences, and expansive professional spaces. Utilizing energy-efficient cone aerodynamics, it delivers long-range projection that propels purified air over 10 meters (32 feet), circulating over 80 liters of air per second while remaining acoustically engineered to operate 50% quieter in Night mode than standard Dyson purifiers.

Filtration is managed through a fully sealed, 3-stage filtration assembly:

• HEPA H13-Grade Filter: Captures 99.97% of microscopic particles down to 0.1 microns, trapping ultrafine wildfire smoke, allergens, pet dander, mold spores, bacteria, and viruses. Engineered with substantial media density, it delivers an extended lifespan of up to 11 years.

• Potassium Carbonate-Enriched K-Carbon Filter: Adsorbs 3 times more nitrogen dioxide ($\text{NO}_2$) compared to standard carbon filters, while neutralizing odors, vehicle exhaust emissions, and volatile organic compounds (VOCs).

• Selective Catalytic Oxidization (SCO) Filter: Traps and permanently breaks down formaldehyde molecules into water and $\text{CO}_2$ at a molecular level without ever needing replacement.

Equipped with a suite of environmental sensors, the machine continuously monitors fine particulate matter, chemical gases, and room ventilation requirements. The integrated $\text{CO}_2$ sensor alerts users when carbon dioxide levels reach 1,500 ppm or higher, prompting room ventilation for optimal focus and well-being. Airflow can be directed at 0°, 25°, or 50° angles, or switched to Breeze Mode to mimic natural outdoor breezes. Through the MyDyson™ app, users can access live environmental reports, set scheduling, and control the purifier remotely or via compatible voice assistants.

Key Features

• Long-Range Airflow Projection: Propels clean air over 10 meters, delivering over 80 L/s of purified air throughout large spaces.

• Acoustically Engineered Quiet Operation: Operates with minimal noise, featuring a Night mode engineered to be 50% quieter.

• Dedicated $\text{CO}_2$ Sensing: Alerts when carbon dioxide levels rise above safe thresholds to prompt natural ventilation.

• Triple-Capacity $\text{NO}_2$ Capture: K-Carbon filter captures 3x more nitrogen dioxide gas than standard Dyson carbon filters.

• Continuous Formaldehyde Destruction: Permanent catalytic filter breaks down formaldehyde into water and $\text{CO}_2$ without replacement.

• Up to 11-Year HEPA Filter: High-capacity HEPA H13 filter traps 99.97% of pollutants down to 0.1 microns for up to 11 years.

• Adjustable Projection Angles: Customize airflow direction between 0°, 25°, and 50°, or activate Breeze Mode for variable airflow.

• Fully Sealed Machine Construction: Prevents dirty air bypass to ensure captured particulates remain sealed inside.

• MyDyson™ App & Voice Control: Manage schedules, track pollutant history, and control with Amazon Alexa, Google Assistant, or Siri.

• Curved Magnetic Remote: Securely docks on top of the purifier for quick manual control.
