Bedroom Air Filters Help Asthmatic Children Breathe Easier

Using a bedroom air filter that traps fine particles of pollution with diameters smaller than 2.5 micrometers can significantly improve breathing in asthmatic children, a new study by American and Chinese scientists shows.

Using a bedroom air filter that traps fine particles of pollution with diameters smaller than 2.5 micrometers can significantly improve breathing in asthmatic children, a new study by American and Chinese scientists shows.

It’s the first study to document that physiological improvements occur in the childrens’ airways when air filters are in use, and it suggests that with consistent use, the filters may help prevent, not just alleviate, asthmatic flare-ups.

While using the filters daily for two weeks, children in the study experienced decreased airway resistance and lung inflammation and increased airway elasticity, among other benefits.

“Pharmaceutical companies have spent large amounts to develop drugs that can work on lower airways, but they are very expensive. Our results show that using an air purifier to reduce the exposure of lower airways to pollutants could help asthmatic children breathe easier without those costly drugs,” said Junfeng Zhang, professor of global and environmental health at Duke University’s Nicholas School of the Environment.
