The K-Carbon Filter Breakthrough
The HP2 De-NOx introduces Dyson’s revolutionary K-Carbon filter, capturing 50% more nitrogen dioxide than traditional carbon filters while continuously destroying formaldehyde—a critical advantage during winter months when closed windows trap indoor pollutants.
Both models feature fully sealed HEPA H13 filtration systems ensuring captured pollutants remain contained within the purifier, addressing a common complaint about lesser air purifiers that leak unfiltered air around seals.
Smart Monitoring Meets Real Action
Built-in sensors automatically detect airborne pollutants like dust, allergens, and gases such as NO₂, adjusting purification levels in real-time. The devices use Air Multiplier technology to project over 290 liters of air per second with 350-degree oscillation for whole-room coverage.
Users can control both purifiers via the MyDyson app or voice commands through Alexa, Google Assistant, and Siri—tracking filter life, scheduling operations, and monitoring air quality remotely.
Year-Round Comfort, Single Device
Unlike standalone air purifiers, these units intelligently heat during winter and cool during summer, eliminating the need for separate appliances. The timing couldn’t be better—Delhi’s AQI regularly exceeds 400 during November-December, making indoor air quality management essential.
Both purifiers are available on Dyson’s website and Dyson stores across India, with the HP2 De-NOx targeting households serious about tackling harmful gases, while the HP1 offers comprehensive particle filtration at a more accessible price point.
