Ever wondered if those indoor air cleaners really work? A study at Johns Hopkins says yes. However, not only do they work, but that's the best solution for a child who suffers from asthma symptoms, or for someone who lives with a smoker. Researchers at Johns Hopkins studied about a hundred kids who lived with smokers. They found those who were given two free-standing air cleaners had more days without coughing, wheezing, or difficulty breathing. The air cleaners did not lower nicotine levels in the air, and researchers say living in a smoke-free home is still the best option for children. However, their study found that air cleaners can be used effectively as a tool to remove pollutants in the air, at least temporarily.
