    The Austin Air Bedroom Machine® was used in clinical trials at the University of John Hopkins to reduce Nitrogen Dioxide levels in the homes of local residents. Nitrogen Dioxide (NO2) is a gas often present in homes where there are gas stoves. High levels of NO2 are particularly dangerous for people with COPD. The gas can dramatically increase symptoms of coughing, wheezing and chest tightness. The results were dramatics. NO2 dropped in the kitchen by 27% and continued to stay low for the length of the study. Within a week NO2 levels in the bedroom dropped by 23%.

    In a second study at John Hopkins, the Bedroom Machine ® was placed in the homes of women, living with a smoker, who were either pregnant or with very young babies. Again the results were impressive. It was clinically proven that running an Austin Air Bedroom Machine® will effectively remove indoor pollutants from the home, including nicotine.

    The Bedroom Machine® addresses the broadest spectrum of air cleaning by removing sub-micron particles including allergens and asthma irritants, noxious gases, odors and chemicals. Austin Air’s 360-degree intake system draws air into all sides of the Bedroom Machine®, passing it through a comprehensive 5 stages of filtration.

    The result? More clean air delivered faster and more efficiently than any other air purifier on the market.
