This Dyson Purifier Cool Purifying Fan is an air purifier and cooling fan all-in-one. It keeps the air in your home clean and healthy, while also keeping you cool during warmer weather. This makes it ideal for your working from home office, bedroom, and more! The Dyson Air Multiplier™ technology draws in pollutants from far away and releases purified air into the room. The Dyson air purifier captures bacteria, allergens, and dust. It also has sensors that automatically display, diagnose and react to the air quality. This Dyson cooling fan and purifier moves up to 360° so air is purified throughout the room. The HEPA+Carbon filter captures many gases and tiny particles. The Dyson Link app lets you know when you need to replace the HEPA+Carbon filter. You never need to replace the catalytic filter in this Dyson cooling fan and air purifier. You can easily monitor and control the air quality from your device with the Dyson Link app, or compatible voice services. Light sleepers will love the night mode of this Dyson purifier with its dimmed display and quiet settings. In colder months when you need to purify the air without keeping cool, you can use the diffused mode. This mode purifies the air without cooling you.
