Dyson Purifier Hot+Cool HP2 De-NOx - Powerful Purification & Climate

Our review of the Dyson Purifier Hot+Cool HP2 De-NOx finds it best for households that need a single device to heat, cool, and significantly improve indoor air quality. The most compelling reason to buy is its advanced NO2 capture and fully sealed HEPA H13 filtration that targets 99.97% of particles as small as 0.3 microns while also continuously destroying formaldehyde, making it a practical choice where gases and fine particulates are a concern.

Key Features

• Advanced NO2 capture: Captures 50% more nitrogen dioxide to reduce harmful gas exposure in urban or traffic-adjacent homes.
• HEPA H13 sealed filtration: The fully sealed, three-stage filter system captures 99.97% of particles down to 0.3 microns for consistent particulate removal.
• Formaldehyde destruction: Continuously destroys formaldehyde, addressing a common indoor volatile organic compound that filtration alone may not remove.
• Heating and cooling: Dyson Air Multiplier technology projects over 76 gallons per second of airflow for effective cooling and whole-room heating to maintain comfortable temperatures year-round.
• Smart control: Connects to the MyDyson app and compatible voice services so users can monitor and control air quality, set schedules, and view reports remotely.
• Design and convenience: Smooth oscillation up to 350 and a magnetized remote that stores neatly on the machine for simple directional control.

Who It's For

This purifier is aimed at people who want a multi-function appliance that replaces separate heaters or fans while improving indoor air quality, particularly those living in areas with traffic pollution or who are sensitive to gases and fine particulates. Families, home offices, and anyone concerned about formaldehyde or NO2 exposure will appreciate the sealed HEPA H13 system and continuous formaldehyde removal.

Those on a tight budget or who only need basic particulate removal in a single small room may want to look at more affordable, single-function purifiers. Also, buyers who prefer simple, no-app devices might find the smart features unnecessary.

Pros & Cons

Pros

• Effective combined heating, cooling, and air purification with powerful airflow for whole-room coverage.
• Advanced gas and NO2 capture plus continuous formaldehyde destruction adds protection beyond standard HEPA filtration.

• Quiet operation is noted by customers, making it suitable for bedrooms and living spaces.

Cons

• Premium price means it may feel expensive for some buyers compared with basic purifiers.
• Mixed opinions on build quality suggest prospective buyers inspect in person where possible.
