Dyson Purifier Cool PC1 vs Purifier Hot+Cool HP1

The Dyson Purifier Cool PC1 edges out the Dyson Purifier Hot+Cool HP1 as an air purifier. It delivers somewhat stronger particle filtration, making it a better choice for improving air quality, though both models are ultimately best suited to smaller rooms. They share many of the same convenience features, including app connectivity, a remote control, and automatic fan speed adjustment. The HP1's main advantage is its built-in heating function, allowing it to double as a space heater, and it also runs a little more quietly during normal air purification.
