text: 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.
text: General guidelines: For best results during the treatment phase, ozone is applied once or twice daily, or perhaps every other day, in concentrations varying from 1 to 80 micrograms per cubic milliliter (mcg/ml3), in as great a quantity as can be safely and comfortably absorbed by the body.
