This two-in-one air purifier and fan is light and handy. It features a 360-degree air inlet and a 3-layer purification system using a new composite filter technology. These, in conjunction with a high-efficiency motor, deliver a filtration rate of 99.9 which is sufficient to filter formaldehyde, PM2.5, dust mites, hair, and mold spores. Design features include a wide angle air outlet, multi-colored lights to show current air quality, and a super silent operation (30 dB), as quiet as the sound of the breeze passes your ears, the kind of sound that sends babies to sleep.
