-Ozone toasts your lungs and can cause heart impairment.-
I'm sorry i cannot agree with that.I guess I must be the walking dead because I've had 1 to 2 pppm ozone in my house for over ten years. If this statement were true, no-one should go outside on a hot sunny day because the natural ozone levels in air from the sun are well above the EPA, OSHA and FDA guidlines for safety.
