Why Buy?
One tower for cleaner, warmer or cooler air all year
The Dyson Purifier Hot+Cool HP2 De-NOx Purifier does the job of a heater, fan and air purifier in a single white and gold tower, which is exactly what most people searching for the dyson hp2 hot+cool de-nox purifier want to replace three separate appliances with one. It captures fine particles and gases, breaks down formaldehyde rather than just trapping it, and adsorbs 50% more NO2 than earlier Dyson models, so the air circulating through your home is genuinely cleaner, not just filtered on paper.
Because the whole system is sealed, purified air stays purified instead of mixing with pollutants caught inside the machine. In summer, Air Multiplier technology pushes out over 290 litres of airflow a second with wide 350-degree oscillation, so cooling reaches every corner of a room rather than just the spot directly in front of it. In winter, the same tower projects warm air evenly across the whole space, so you are not huddled near a small heater waiting to warm up. A live display shows exactly what is in the air at any moment, so you know what you and your family are actually breathing.
Its slim footprint suits a bedroom, living room or study without eating up floor space. Night mode dims the display and drops to the quietest settings for lighter sleepers, while the MyDyson app and compatible voice control let you check air quality and adjust settings from another room. It comes with a remote control, a 360 Glass HEPA H13 filter, an activated carbon filter and an SCO filter.
Buy this if…
- You want purifying, heating and cooling handled by one device instead of three
- Your home has new furniture, flooring or paint that could be releasing formaldehyde
- You or your family manage allergies, asthma or general air quality concerns
- You like checking and adjusting air quality remotely through an app
- You need quiet, dimmed operation that suits a bedroom or shared living space
