The AIR4 is the first and only three-way bladeless fan that also offers powerful purification and sterilization of indoor air. The lightweight design is easy to move and quiet when in use. Three air ducts enhance efficiency by using the same amount of power as traditional dual-air ducts while increasing output. It also ensures better cross flow and eliminates bothersome drafts for a comfortable 360-degree cooling experience. The operator panel makes it easy to select between modes, and the onboard ultraviolet sterilization and HEPA filter effectively purify the air.
