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. Its standout feature is the advanced 3-stage HEPA H13 filter that captures 99.97% of tiny particles, including allergens and pollutants as small as 0.3 microns. This model is distinguished by its ability to remove nitrogen dioxide (NO₂) and continuously destroy formaldehyde, which many other purifiers don’t handle as effectively.

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.

This air purifier is ideal for users seeking a high-tech, multi-function device that not only cleans the air efficiently but also provides heating and cooling, especially if indoor air pollution from gases is a concern. However, its coverage size may be limited for larger rooms or open spaces.

The Dyson Purifier Cool PC1 is a well-built air purifier that combines a HEPA filter with an activated carbon layer, effectively capturing 99.97% of tiny allergens and pollutants, as well as removing common odors from pets, cooking, and smoke. Its fully sealed design ensures that trapped particles stay inside the device, which is reassuring for allergy sufferers. This model is designed for smaller rooms, covering up to about 101 square feet, so it fits nicely in bedrooms or offices rather than large living spaces.

Dyson's Air Multiplier technology pushes a good amount of airflow, which doubles as a cooling fan during warmer months — a handy dual-purpose feature. The purifier oscillates smoothly to spread clean air evenly around the room. It’s also convenient to control remotely or via the MyDyson app, which lets you monitor air quality and set schedules from anywhere, adding a modern touch to comfort and convenience.

The device weighs over 10 pounds and requires assembly, which might be a minor hassle for some users. Also, with a floor coverage on the smaller side, it may not be the best fit if you need to purify large areas or multiple rooms. The price point and brand reputation suggest good reliability and quality. This purifier suits users looking for strong allergen and odor removal in small spaces, with the bonus of cooling airflow and smart controls.
