CBS News reports that ozone pollution (smog) is making breathing difficult for children who have asthma.

‘On days of high levels of ozone, people with asthma are more likely to have symptoms or shortness of breath,’ says Dr. Homer Bouchley of the University of California.

‘When he has his attacks, you can see his ribs,’ say Qiana Abram, mother of 18-month-old Walter, who has asthma. ‘He's hurting. I cry for him.’

Studies done by researchers at Yale and Johns Hopkins show that smog can actually kill. In the studies, an increase in daily ozone levels was associated with more than 3,700 additional deaths each year due to cardiovascular and respiratory illnesses.

As unbelievable as it may seem, many popular ionic air cleaners actually produce ozone!

If you're looking for a safe air purifier to effectively remove allergens from your home, you should avoid those that produce ozone. See New to Air Purifiers for more introductory information.
