Dyson Purifier Big+Quiet Formaldehyde BP04

Description

• Powerful Large-Room Air Purification: The Dyson Purifier Big+Quiet Formaldehyde BP04 is engineered to purify large indoor spaces while maintaining exceptionally quiet operation. Using Dyson’s advanced airflow projection technology, it distributes purified air over 32 feet (10 meters), helping circulate cleaner air throughout spacious living rooms, bedrooms, offices, and open-plan environments.

• Advanced HEPA H13 Filtration System: Featuring a fully sealed three-stage filtration system, the BP04 combines a HEPA H13-grade filter, K-Carbon filter, and permanent catalytic filter. The system captures 99.97% of airborne particles as small as 0.3 microns, including fine dust, pollen, and other allergens, while also helping remove airborne gases and unpleasant odors.

• Permanent Formaldehyde Destruction & Enhanced NO₂ Removal: Equipped with Dyson’s specialized solid-state formaldehyde sensor and Selective Catalytic Oxidization technology, the BP04 continuously detects and destroys formaldehyde molecules. Its advanced K-Carbon filter is designed to capture three times more nitrogen dioxide (NO₂) than Dyson’s standard activated carbon filter under specified testing conditions, making it especially useful for homes exposed to urban air pollution.

• Intelligent Air Quality Monitoring with CO₂ Detection: Built-in sensors continuously monitor airborne particles, gases, formaldehyde, and carbon dioxide levels. The integrated CO₂ sensor alerts users when indoor carbon dioxide concentrations become elevated, while Auto Mode automatically adjusts purification performance according to detected air quality. Real-time information is available through the onboard LCD display and MyDyson app.

• Ultra-Quiet Performance & Adjustable Airflow: Designed with Dyson’s innovative noise-reduction technology, the BP04 delivers powerful purification with reduced operating noise. Choose from 10 airflow speed settings and three airflow projection angles of 0°, 25°, and 50°. Night Mode and Sleep Timer functions provide additional convenience for comfortable everyday operation.

• Smart App Control & Long-Lasting Filters: Connect the purifier to the MyDyson app to monitor indoor air quality, adjust operating settings, create schedules, and receive filter maintenance notifications. Compatible voice services and the included magnetic remote control provide convenient operation. The HEPA filter is designed to last up to five years, while the K-Carbon filter is recommended for replacement approximately every two years under specified usage conditions.

Important Notes: The BP04 is an air purifier with a fan cooling function, not an air conditioner or humidifier. Its CO₂ sensor monitors and reports elevated carbon dioxide levels but does not actively remove CO₂ or replace proper ventilation. Filtration performance, noise levels, and filter lifespan are based on manufacturer-specified testing and usage conditions. Actual results may vary depending on room size, indoor pollution levels, airflow settings, and maintenance.
