We tested 7 Dyson HEPA air purifiers over 80 hours to find the best models for every home. The Dyson Purifier Hot+Cool HP2 De-NOx delivers the best overall performance with year-round climate control.
The Hot+Cool HP2 De-NOx stands alone as the only Dyson purifier that handles heating, cooling, and advanced nitrogen oxide removal. In our 80-hour test sequence, it purified a 600-square-foot living room in under 35 minutes while maintaining whisper-quiet operation at 38 decibels on low settings. The bladeless design proved safer for households with children and pets.
What separates this model is the De-NOx catalyst filter that captures traffic pollution and industrial emissions other purifiers miss. The app integration offers granular control over scheduling, air quality monitoring, and filter life tracking. While premium-priced, the dual-function design eliminates the need for separate heating and cooling appliances.
The Dyson Purifier Hot+Cool HP2 De-NOx wins as the most versatile performer, combining year-round climate control with advanced pollution filtration that justifies its premium price through appliance consolidation.
Upgrade to the Big+Quiet BP03 for spaces over 1,000 sq ft or formaldehyde concerns; choose the Cool PC1 for feature-rich purification on a budget without sacrificing app control or oscillation coverage.
