Product Overview
The HP2 De-NOx focuses on gas-phase pollutants, particularly nitrogen dioxide from cooking and combustion sources. Combined with sealed HEPA filtration and integrated heating and cooling, it functions as a year-round air treatment system rather than a single-purpose purifier.
The HP2 De-NOx is Dyson’s purifier-heater-fan built around a fully sealed 3-stage filtration system. Its defining mechanism is a K-Carbon filter impregnated with potassium carbonate, designed to adsorb 50% more nitrogen dioxide than standard activated carbon, alongside HEPA filtration and formaldehyde destruction.
Why Plumosity Certified It
It fits Plumosity Certified because its value comes from identifiable engineering: K-Carbon NO₂ adsorption, sealed HEPA H13-grade filtration, formaldehyde destruction, and whole-room air projection supported by consistent customer feedback and a verified industry award.
