Is Ozone Safe To use in The Home and Air Conditioner System?
Use of ozone to “remove” or “kill” mold is ineffective, not recommended, and may be dangerous. Even if ozone were applied at a concentration and for a duration sufficient to “kill” every mold spore in a building (which is a very dubious claim), depending on the mold genera/species present there is a good chance that the process leaves toxic and allergenic particles in the building. A “dead” (or non-viable) mold spore may not grow but it can still be a health concern. The operative proper word for mold remediation is “clean” or “remove”, not “kill.” In 1997, Dr. Karin K. Foarde of Research Triangle Institute, tested the ability of ozone to decontaminate fungi on building materials. At ozone levels of 9 ppm for a 23-hour exposure, ozone was found to be ineffective. Problems from ozone exposure include: • Lung irritation and infection. Breathing pain, coughing, wheezing, difficulty when exercising. • Permanent lung damage.
