This purifier fan heater from Dyson combines three appliances in one. It heats and cools your room as well as capturing dust, allergens and bacteria – even destroying formaldehyde. Enjoy amazingly clean air and always feel the perfect temperature with the HP09.

Purified Air

Whether you’re feeling chilly in the winter, hot during the summer, or just want to know you’re beathing pure air, the Hot + Cool Air Purifier does it all. Featuring a catalytic filter unique to Dyson, it continuously traps and converts formaldehyde into water and CO2. And, as its self-regenerating, you’ll never have to replace it.

Air Multiplier technology and an oscillation and tilt mechanism project air throughout the room. You’ll get over 290 litres of smooth, purified air pumped out every second, meaning you can enjoy it wherever you’re sitting.

What’s more, the HP09 is the only purifier to be fully sealed to HEPA H13 standard, capturing 99.95% of allergens and pollutants inside the appliance. Always breathe easy with Dyson.

Easy to Use

Keep control with the included remote, which you can store on top of your purifier. Try out spoken instructions through Alexa, Siri, or Google Assistant or use the Dyson Link app for simple monitoring on a Wi-Fi and Bluetooth-enabled device.

Available on both Apple and Google app stores, it lets you know all about your air quality and filter life, and you can change settings remotely. The HP09 even shows you the particles and gases it has detected and sends a report to your device. Or, see them in real time as well as the room temperature, on the integrated LCD screen.

Try Diffused Mode if you want purified air without the cooling. Airflow is directed through the back of the machine, maintaining effective purification. If you prefer the HP09 to run at night, the Sleep mode will run quietly in the background whilst dimming the display, so your sleep is not disturbed. Plus, set the temperature and choose up to 10 speed settings for the perfect atmosphere in any room.

Experience amazing air quality, plus convenient heating and cooling, with the white and gold Dyson HP09. Buy yours now.
