The BioGS design story

BioGS air purifier

reddot award 2014 winner The BioGS's redesign is much more than a facelift. We dug deep to reconsider the fundamental facets of our product, including the air purifier's shape and form, user interface, and functionality. We also ruminated on its impact on the environment, which led us towards a more holistic approach, cutting back on light and sound pollution generated by the air purifier to ensure that while it takes pollutants from the environment, it leaves nothing but clean air in return.

Industrial designer Guto Indio da Costa’s concept of "flow" resonates throughout the BioGS 2.0. The curvaceous body of the air purifier reflects its relatively simplistic but comprehensive functionality, and its clean, cool, and straightforward style. By reimagining the air purifier's structure and streamlining its bells and whistles, da Costa has steered the latest generation of Rabbit Air products towards growth and progress, with a new model that’s easy to use, less intrusive, and aesthetically pleasing.

Charcoal-based activated carbon filter

The Rabbit Air activated carbon filter uses high grade granular activated carbon to purify the air. The performance of our AC filter is much higher than a typical AC filter, which is merely coated with a thin layer of activated carbon. Chemicals and odors from cooking, pets, smoke, VOCs and other sources can be effectively eliminated.
