The Dyson 969897 remote control is designed for select Dyson Purifier Hot+Cool models, including De-NOx and Formaldehyde editions. It provides direct access to heating, cooling, oscillation, airflow speed, and purification modes with no programming required for compatible units. This is an IR-only remote and works exclusively with supported Dyson Hot+Cool purifying heaters, not with Dyson cool-only purifiers or other Dyson appliances. Same as: 969897-05
