Indoor air cleaners help for asthma

Indoor air cleaners can greatly reduce household air pollution and lower the rates of daytime asthma symptoms to those achieved with certain anti-inflammatory asthma drugs.

A Johns Hopkins Children's Centre study of Baltimore City children who have asthma and live with smokers shows that indoor air cleaners can greatly reduce household air pollution and lower the rates of daytime asthma symptoms compared to those achieved with certain anti-inflammatory asthma drugs. Although the air cleaners improved the overall air quality in homes, they did not reduce air nicotine levels and did not counter all ill effects of second-hand smoke, the researchers warn.

"Air cleaners appear to be a an excellent partial solution to improving air quality in homes of children living with a smoker, but should not be viewed as a substitute for a smoke-free environment," says lead investigator Arlene Butz, an asthma specialist at Johns Hopkins Children's and professor of paediatrics at the Johns Hopkins University School of Medicine.
