Air Rating, Inc. is a Michigan corporation with a mission to make available indoor air quality ratings to the public so users can validate the hygiene of the places they visit, live, or work at. Our goal is for everyone to know the quality of the air in any given indoor space at any given time. We believe this awareness will help people choose locations with good air quality and will eventually drive improvements in indoor air quality worldwide. Our solution to make available indoor air quality comprising an air sensor, smartphone application, and AWS cloud is patent pending at the US Patent and Trademark Office (publication #20230408477).
