Product Description

A closer look at Dyson Purifier Big+Quiet Formaldehyde BP04 shows why it fits large-room air purification with formaldehyde destruction and long-range airflow. The connectivity is MyDyson app, while the filtration is HEPA H13, K-Carbon and catalytic formaldehyde filtration. The first feature adds remote monitoring and control from a phone; the second targets particles, gases and formaldehyde through separate stages. The catalytic formaldehyde filter is the defining BP04 feature because it continuously destroys formaldehyde rather than relying only on a finite adsorption layer.

Why We Chose It

• Useful on BP04: 99.97% down to 0.1 micron particle capture; this clarifies who the model suits best.
• BP04 benefit: HEPA H13, K-Carbon and catalytic formaldehyde filtration; this helps size the unit for its room.
• Over 32 ft air projection. For BP04, this makes the specification more useful.
