Hello Everyone
There are many IAQ devices that are supposed to improve your indoor air quality and consequently your health. However, some of these devices are producing high levels of ozone as a by product. This is not a healthy situation and can result in severe lung damage. You can go the the American Lung Association to get an unbiased view on the harm of high ozone levels ( anything above 50ppb ). Please keep in mind that the half life of ozone is greater than a day at 72 degrees and 50% humidity. This means that if your IAQ device is producing ozone above 50 ppb and is running 24/7 you are in trouble. Please take a look at this ozone testing on some popular IAQ devices. go to youtube.com/watch?v=kn7JEdR1O9o
