Question 1

Has Austin Air been clinically tested?

Accepted Answer

Yes. Austin Air is the only air purifier manufacturer to partner with leading research institutions to conduct independent clinical trials on its products. Ten trials have been completed or are ongoing, with positive results in every published study.

Question 2

Which institutions have conducted clinical trials with Austin Air?

Accepted Answer

Clinical trials involving Austin Air purifiers have been conducted by Cincinnati Children's Hospital (with the American Academy of Pediatrics), Johns Hopkins University (multiple studies including the CLEAN AIR Study), the University of Washington (HAPI Study), Franklin W. Olin College of Engineering, the University of Connecticut (HAFTRAP Study, published in Scientific Reports), Illinois Institute of Technology and Jesse Brown VA Medical Center (Veterans COPD trial), and the University of Massachusetts / UMass Lowell (67-home gas stove NO₂ and PM2.5 study).

Question 3

What health conditions have Austin Air purifiers been shown to help?

Accepted Answer

Published clinical trials demonstrate that Austin Air purifiers reduce children's asthma symptoms and ER visits, lower indoor nitrogen dioxide in homes with gas stoves, reduce PM2.5 and cotinine for pregnant women and infants, improve air quality for children in agricultural areas, lower blood pressure in people exposed to traffic-related pollution, reduce COPD symptoms and flare-ups, improve cognitive function in adults 40 and older, reduce particulate matter in environmental justice communities with high asthma rates, and are currently being evaluated in a year-long Veterans COPD trial.

Question 4

What is the HAFTRAP study?

Accepted Answer

The HAFTRAP (Home Air Filtration for Traffic-Related Air Pollution) study was a pragmatic randomized crossover trial involving 119 participants, published in Scientific Reports (Nature) in April 2026. Adults 40 and older completed cognitive tests measuring mental flexibility and executive function 12% faster after using the HEPA Austin Air purifier — an improvement comparable to the cognitive benefits of daily exercise.

Question 5

What is the CLEAN AIR Study?

Accepted Answer

The CLEAN AIR Study was a blinded randomized controlled trial by Johns Hopkins University in which 116 former smokers with moderate-to-severe COPD were monitored for six months. Those using active Austin Air HEPA purifiers showed significant reductions in respiratory symptoms, exacerbation risk, and rescue medication use.

Question 6

Is Austin Air better than other HEPA air purifiers?

Accepted Answer

Austin Air is the only air purifier manufacturer whose actual products have been tested in independent clinical trials by research hospitals and universities including Johns Hopkins, Cincinnati Children's Hospital, and the University of Washington — with results published in peer-reviewed journals. Most competing brands rely solely on laboratory filter ratings, not real-world clinical health outcomes.

Question 7

Can an air purifier improve health outcomes?

Accepted Answer

Yes, based on clinical evidence. Across ten independent trials, Austin Air purifiers produced statistically significant improvements in measurable health outcomes including fewer asthma attacks and ER visits in children, reduced COPD exacerbations and rescue inhaler use in adults, lower blood pressure in people exposed to traffic pollution, and improved cognitive test scores in adults 40 and older.

Question 8

Are Austin Air purifiers safe for babies and pregnant women?

Accepted Answer

Yes. Clinical trials have specifically tested Austin Air purifiers with pregnant women and infants (Johns Hopkins, Trial 3), children with asthma (Cincinnati Children's Hospital, Trial 1), and an ongoing Johns Hopkins study focuses on infants and young children (Trial 7). Austin Air units produce no ozone, no ionization byproducts, and no UV radiation.
