The Dyson HP2 De-NOx is engineered to tackle modern indoor pollutants. Its advanced K-Carbon filtration is specifically designed to absorb NO₂, a common byproduct of gas cooking and vehicle emissions, at a much higher rate than standard filters. This is paired with a lifetime catalytic filter that continuously traps and breaks down formaldehyde molecules into water and CO₂, ensuring it never needs replacing.
Using Air Multiplier™ technology, the machine draws in distant pollutants and projects over 76 gallons per second of purified air. It can heat a whole room evenly in winter or provide a powerful stream of cooling airflow during the summer. The entire machine—not just the filter—is fully sealed to HEPA H13 standards, ensuring that what goes inside stays inside. Smart features allow you to monitor air quality in real-time via the MyDyson™ app and control the device using voice-activated assistants.
