Dyson Hot+Cool AM09

Yes, the Dyson Hot+Cool AM09 functions as a space heater in colder months and a cooling fan in warmer weather, using Dyson's bladeless Air Multiplier technology for both modes. Heating mode uses a ceramic heating element, while fan mode projects a smooth stream of unheated air.

The AM09 is a heater and fan combination only, while newer Dyson Pure Hot+Cool models (such as the HP04 and HP07) add a True HEPA filter for air purification. The Pure Hot+Cool line also includes sensors that detect airborne particles and gases and automatically activate purification, which the AM09 does not offer.

Yes, the AM09 includes a precise thermostat that monitors room temperature and automatically cycles the heating element on and off to maintain your selected target temperature. It also includes a timer function that can be set to turn the unit off automatically.

While Dyson's bladeless Air Multiplier design produces smoother, less turbulent airflow than traditional bladed fans, the AM09 still generates a noticeable level of air noise on its highest of the available speed settings. Some users find the top speed too loud for quiet environments like bedrooms.
