The Effect of HEPA Air Purifiers on Asthma Related Doctor Visits
Today, more than 20% of children in the United States are exposed to secondhand smoke in their homes. In an effort to find a method for reducing asthma morbidity, doctors from the Child and Family Research Institute of the British Columbia Children’s Hospital, the Cincinnati Children’s Environmental Health Center, Department of Pediatrics and the Department of Epidemiology at the University of North Carolina, Chapel Hill conducted a study on the effects of high efficiency particulate air (HEPA) filters in regards to unscheduled asthma visits and symptoms in children exposed to secondhand smoke at home.
The doctors studied 225 children between the ages of 6-12 with physician-diagnosed asthma that were exposed to five or more cigarettes per day in their home. It was a double blind trial in which the children were randomly selected to receive 2 active or inactive Austin Air HealthMate air purifiers for the duration of the study. Of the 225 children, 110 were assigned to the intervention group with active HEPA air purifiers and 115 were assigned to the control group with inactive HEPA air purifiers. In the end, 215 of the children completed the trial. Children in the intervention group had 42 less doctor visits for asthma related symptoms during the trial, which after adjusting for the 10 children who did not complete the study resulted in an 18.5% decrease compared to the control group. Between the two groups, there was a noteworthy difference between parent-reported asthma symptoms, air nicotine levels, exhaled nitric oxide levels and cotinine levels.
The most significant finding in the study was that homes with active HEPA air purifiers showed a 25% decrease in airborne particles greater than 0.3 microns in size. Homes with inactive HEPA air purifiers only saw a 5% decrease in airborne particles of the same size. The doctors concluded that HEPA air purifiers were a great step in the right direction for reducing secondhand smoke related problems in children.
At Clean Air Plus, we only sell top quality HEPA air purifiers. HEPA air purifiers work by first filtering out larger airborne particles, than smaller particles you cannot see with your naked eye, but easily work their way into your respiratory system, then finish with an activated charcoal filter that removes vapors and other gasses from the air. With these three steps working together, the air in your home can be virtually free from all pollutants.
