The Only Clinically Proven Medical Grade Air Purifiers

Our involvement in clinical trials started in 2001 when we were selected by the American Academy of Pediatrics and the country’s number one children’s hospital, Cincinnati Children’s Hospital, to take part in a clinical trial.

The aim of the study was to measure how an Austin air HealthMate could help to reduce children’s asthma symptoms and minimize visits to the ER. The air purifiers were run in the bedroom at night and in the main family room during the day. Over a twelve-month period, the children’s asthma improved and the number of visits to the emergency room was reduced dramatically.


The success of this trial paved the way for others. In 2009 we were approached by the renowned

John Hopkins University Hospital Baltimore. This time to measure how effectively our Bedroom Air purifier  could reduce levels of indoor Nitrogen Dioxide. Nitrogen Dioxide (NO2) is a gas often present in homes where there are gas stoves. It is particularly dangerous for people with COPD, as it can cause coughing, wheezing and chest tightness. Again participants were given two Austin Air Purifiers, to be used in the kitchen and the bedroom. Again, results were impressive, NO2 levels dropped and air quality improved significantly.


Shortly after, we teamed up with Johns Hopkins University Hospital for a second time. This study was designed to measure how using an Austin air Bedroom Machine could improve indoor air quality for pregnant women or women with very young children, living with a smoker. Again two Austin Air Purifiers were installed in each home. And once again it was clinically proven that our air purifiers are extremely effective at removing PM2.5 and what’s more, 98% of the women said they would recommend an Austin Air Purifier to friends and family looking to improve indoor air quality.


We went on to conduct a number of studies with Johns Hopkins and are still working with the university at the time of writing.

In 2015, we partnered with the University of Washington, where preliminary tests indicated the Austin air pet machine would be successful at removing ammonia. This was the start of a more comprehensive clinical trial, that will investigate further the efficacy of using an Austin Air Purifier to remove ammonia from the home.

And this year we joined forces with Franklin W. Olin College of Engineering in Boston, to improve air quality for residents living near to the airport in East Boston. Both studies are ongoing, and we very much look forward to the published results.

Three published clinical trials, three successful outcomes. And although the results of the trials confirm what we have known for many years, this has been a real game changer for us. We have achieved something no other air purifier has. Independently tested, by some of the country’s leading hospitals, we were (and still are) the only air purifier to be clinically proven in this way.
