Dyson humidification air purifiers are tested beyond the industry standard.

We test our humidifying air cleaners in an 81 m³ room with nine sensors that continuously measure air quality. Some other manufacturers use a small 28.5 m³ room with only a sensor and a fan to increase circulation.

Captures contaminants with advanced HEPA filtration

The carbon filter captures gases such as benzene, and the HEPA H13 filter captures 99.95% of contaminants as small as 0.1 micron.2

2 Filtration efficiency tested at 0.1 micron (EN1822, ISO29463).

Only the latest Dyson air cleaners are fully insulated to the HEPA H13 standard 3

It is not only the fully insulated filter in the HEPA H13 standard, but the entire humidifying air cleaner that prevents pollutants from leaking back into the air3. That is, what goes in stays inside.

3 Dyson's product filtration efficiency in MPPS has reached 99.95% H13 HEPA as defined by EN1822 compared to other air cleaners according to market data [March 2020]. Product filtration efficiency tests were conducted in a chamber specified in ASTM F3150 in IBR US, in Max mode, using DEHS oil particles according to EN1822.

Eliminates potentially harmful particles

Dyson Ultraviolet Cleaning technology exposes every drop of water to powerful λ275nm UV light. This kills 99.9% of particles in the water. Then, the cleaned water is evaporated by the biostatic 3D air pore and the humidified air is projected into the whole room. 5
