Winner of the prestigious red dot Design Award, the Sensing Room Air purifier deserves to grab the credit. It’s an indoor purifier that you would never want to hide behind the curtains. The pleasing look makes it a device worth to show off and works equally good just like its look. The purifier comes with the pollution indicator to keep you acquainted with the type of air that surrounds you. A red light is an indicator of high pollution, dark purple tells that the pollution level is medium, light purple indicates low pollution, and the light turns bright blue if the air is clean. It promises to eat up to 99.5% of airborne particles, all thanks to the easy-to-clean 3 stage Hepa filter system. With the neat and curved design, this elegant air purifier can be grabbed for $279.
