Dyson Purifier Big+Quiet Formaldehyde BP04

Dyson Purifier Big and Quiet Formaldehyde BP04

This is Dyson's most powerful and advanced air purifier yet, specifically engineered to purify large, open-plan spaces (up to {100m}^2) quietly and effectively. The Purifier Big+Quiet Formaldehyde (BP04) features a groundbreaking 3-stage, fully-sealed HEPA {H13}-grade filtration system that captures 99.95\% of ultra-fine particles. Its exclusive Selective Catalytic Oxidisation (SCO) filter continuously and permanently destroys harmful formaldehyde, while the K-Carbon filter absorbs {3x} more {NO}_2 (a common urban pollutant) than standard carbon filters. With unique Cone Aerodynamics projecting purified air over {10} meters, this machine ensures uniform purification throughout the largest spaces.

The common color is a two-tone finish.
