10 Best Dyson Air Purifiers 2025 in the United States

The Dyson Purifier Cool PC2 De-NOx is a strong choice for those looking to improve indoor air quality, especially in spaces up to around 270 square feet. It features a high-quality H13 HEPA filter that captures 99.97% of tiny particles like pollen, dust, and pet dander, which is excellent for allergy sufferers. A standout feature is its ability to specifically reduce nitrogen dioxide (NO₂) by 50%, along with removing odors and harmful gases such as formaldehyde, making it useful in urban or polluted environments.

Its Clean Air Delivery Rate (CADR) is supported by Dyson's Air Multiplier technology, pushing a smooth but powerful airflow to help circulate purified air effectively and also provide cooling during warmer months. The purifier oscillates up to 350°, helping distribute clean air evenly throughout the room. Users can easily monitor and control air quality remotely via the MyDyson app or hands-free with voice assistants, which adds convenience. The remote control magnetically attaches to the unit for neat storage.

Assembly is required, and the unit is somewhat tall and narrow, which might limit placement options in some rooms. Despite being priced on the higher side, the advanced filtration, added gas and odor removal, and smart features make it a solid investment for those serious about cleaner air. This model is particularly suitable for those who want a purifier that also cools and provides smart monitoring, especially in medium-sized rooms.

The Dyson Purifier Hot+Cool HP2 De-NOx is a versatile air purifier designed for rooms up to about 109 square feet.

The Dyson Air Multiplier technology helps circulate purified air smoothly and powerfully, while enabling switching between heating and cooling functions, making it suitable for year-round use. Control options include a remote and the MyDyson app, which provides scheduling and real-time air quality updates for added convenience and smarter operation. Its height and narrow design save floor space but might not fit all areas easily.

It also supports voice control with compatible smart home systems, which is handy for hands-free operation.
