Frequently asked questions

What is an air treatment appliance?

Air treatment appliances are designed to help improve indoor comfort and air quality. This includes air purifiers, fans, heaters and humidifiers that help manage temperature, airflow, air quality and humidity levels. Dyson offers a range of air treatment solutions that combine multiple functions within a single machine.

What does an air purifier do?

An air purifier is designed to capture airborne particles and help improve indoor air quality. Dyson air purifiers, such as the Dyson Purifier Big+Quiet Formaldehyde Purifying fan, draw air through advanced filtration systems before projecting purified air back into the room. Machines like the Dyson Purifier Hot+Cool HP2 De-NOx Purifying fan heater and Dyson Pure Hot+Cool™ HP00 Purifying fan heater combine air purification with additional comfort features such as heating or cooling.

What is the difference between an air purifier and a fan?

A fan is designed primarily to circulate air and create a cooling effect, while an air purifier is designed to filter airborne particles before projecting cleaner air back into the room. Some Dyson air treatment machines combine purification, cooling and heating in a single device, helping reduce the need for multiple appliances.

Can a Dyson air purifier heat and cool a room?

Yes, selected Dyson air treatment machines combine air purification with heating and cooling functions. Machines such as the Dyson Purifier Hot+Cool HP2 De-NOx Purifying fan heater and Dyson Pure Hot+Cool™ HP00 Purifying fan heater are designed to provide purified airflow while helping create a comfortable indoor environment throughout the year.

Are Dyson air purifiers suitable for people with allergies?

Do air purifiers really work?

The effectiveness of an air purifier depends on factors such as room size, airflow and the specific model being used. Dyson air purifiers use filtration technology to capture pollutants and continuously circulate purified air throughout the room.
