If you’ve been looking for an air purifier that does more than just clean the air, the Dyson Hot+Cool Formaldehyde HP09 presents some impressive features. Currently priced at $649, reduced from $849.99, this air purifier is a worthwhile investment at a more accessible price point.

This innovative device not only purifies the air but also functions as both a fan and a space heater. Suitable for areas as large as 800 square feet, its blade-free oval design projects clean air—warm or cool—across a full 350-degree oscillation range. Weighing just over 12 pounds, it’s easy to move this unit from room to room with minimal effort.

A standout feature of the HP09 is its real-time air quality monitoring, which enhances your understanding of the environment you’re breathing. It provides live data displaying the removal of common pollutants from your home such as dust, smoke, pet dander, and various volatile organic compounds. Users can view temperature, humidity, and air quality metrics on the unit’s LED display or through the MyDyson app, which also includes outdoor air quality data based on your location.

The unit’s catalytic filter effectively breaks down formaldehyde without the need for replacement, while the HEPA and carbon filters—which capture additional pollutants—are designed to last up to one year, with replacements priced at $79.99. Control is made simple via the app or voice commands using Alexa, Siri, or Google Assistant; however, it’s important to note that it does not support Apple HomeKit yet. Additionally, the included remote is necessary to activate heating features for safety. According to a PCMag review, users may find it somewhat noisy on higher settings.
