Now possible with the compact yet elegant Sphere air purifier. The spherical purifier comes with a HEPA and activated carbon filter, as well as a built-in vaporizer to disperse relaxing aromas throughout the room. The integrated ionizer pulls small particles from the air through the filter to create clean air. The activated carbon also removes harmful gases and unpleasant odors. The night light adds extra comfort in the dark. Additionally, since it can also be powered via USB, the Sphere uses 80% less energy than conventional air purifiers.
