Dyson PH3A
Air Purifier, White

Purification and Humidification

This machine purifies and hygienically humidifies a whole room, removing 99.9% of bacteria in the water with Dyson Ultraviolet Cleanse technology. It captures dust, allergens and bacteria, addressing both air pollution and dry air from central heating and air conditioning all year round.

Advanced Sensing and Real-Time Monitoring

Three sensors constantly monitor your air quality, with a unique algorithm that diagnoses pollutants at a molecular level. The machine automatically reacts to purify, maintain your target humidity and reports results in real time.

Two-Layer Filtration System

HEPA H13 and activated carbon filters work together to capture gases and 99.95% of pollutants as small as 0.1 microns. The whole purifier is fully sealed to HEPA H13 standard, ensuring what goes inside stays inside.

Air Multiplier Technology

Only Dyson purifiers feature Air Multiplier technology to purify and humidify the whole room. It generates powerful circulation, drawing pollutants from every corner into the filters and projecting purified, humidified air throughout the room.

Intelligent Humidification

The machine has in-built intelligence that automatically adds moisture to combat dry air. It optimises humidity levels by projecting an invisible stream of evaporated water with no mist.

Ultraviolet Cleanse Technology

Dyson Ultraviolet Cleanse technology exposes every drop of water to powerful 275nm UV light, killing 99.9% of bacteria in the water. Cleansed water is then evaporated by the biostatic 3D air mesh before hygienic, humidified air is projected throughout the room.

Deep Clean Cycle

The hassle-free Deep Clean cycle thoroughly eliminates limescale throughout the machine's water system at the touch of a button.

Rigorous Testing Standards

Dyson purifier humidifiers are tested in a room size of 81m³ with nine sensors that continuously measure air quality, going beyond the industry standard. Some other manufacturers use a small 28.5m³ chamber with only one sensor and a fan to boost circulation.
