If a IG-133- negative ionizer was placed in a room were air circulation was minimal, how long would it take for the ozone produced by the unit to exceed safe limits for humans and animals?
Ozone levels would almost certainly never reach, let alone exceed, safe limits*. Ozone is an unstable, short-lived gas, and does not build up like other gases do (for example, natural gas or propane), unless you’re generating large quantities of it on purpose. We have run IG-133 series ionizers here in every room (sometimes two or more), and ozone was undetectable. And air circulation was minimal, which would maximize ozone levels. What is more, a couple of those ionizers were much more powerful than the ones we offer for sale here. Anyway, all high-density negative ion generators can generate a tiny amount of ozone near the ionizer. Ours can generate amounts well below the EPA standard of .05 PPM (less than .01 PPM), and then only very close to the unit. The ozone level is unmeasurable. You will likely breathe in much more ozone around a photocopier. But here is the bottom line: ozone is an unstable, short-lived molecule, it is destroyed by other molecules of odors and pollutants in t
