Yes, all Dyson purifiers have HEPA filters to capture 99.95% of allergens and pollutants as small as 0.1 microns³.

Dyson Purifiers heat or cool with purified air. They project a powerful airflow to heat or cool like most Dyson fans or heaters, but they also capture dust and allergens removing 99.95% of particles as small as 0.1 microns³. In select Dyson Purifiers, they can also be used for purification only for times you may not need heating or cooling, just diffused mode.

Dyson air purifiers feature a night time mode. This mode uses the machine’s quietest settings. To ensure a comfortable night’s sleep.

Dyson air purifiers and fans work differently to air conditioners. Rather than having cooling elements, using ambient air in the room, the purifying fan uses a powerful stream of airflow to cool you down. The cooling effect comes when the air, projected from the amplifier at velocity, passes over the user’s skin. The higher the fan speed, the more powerful the airflow and cooler the air will feel.

Over time, purifier filters can get clogged up with microscopic pollutants, and even let unpleasant odours back into the room. That’s why we recommend replacing your filter at least every 12 months for optimum filter function, or sooner if your machine alerts you. This is so it keeps on running effectively, for a cleaner environment.

We test beyond the industry standard for real living spaces. Dyson engineers designed the POLAR test to challenge the industry test standard –measuring filtration, sensing and circulation to ensure the whole room is purified properly. CADR is not a measure of purification performance in a real-size room 28.5m³. Two additional fans boost circulation. Only one sensor measures air quality. Dyson’s POLAR test goes further to measure purification throughout a real-size room 81m³. No additional fans. Nine different sensors to measure even-room air quality.
