Engineered to be 75% quieter.
The new Dyson Hot+Cool™ fan heater has been engineered to be 75% quieter than the previous generation. To lower noise levels, streamlined airflow paths direct air through the machine with greater efficiency and reduced turbulence. During development and testing, engineers used a semi-anechoic chamber to measure sound power levels, and high-speed cameras to help identify and visualise airflow turbulences.
