The Dyson Pure Hot + Cool Link™ purifier heater has triple functionality.
As a purifier, it removes 99.97% of allergens as small as 0.3 microns from your home. It automatically monitors, reacts, and reports to your Dyson link app, so you can remotely control your environment.
It's also a heater and a cooling fan. With Jet focus control, it enables you to select personal mode for a powerful stream of focused air, or diffused mode for wide projection.
