Does ozone kill mold

Ozone kills everything living. It also destroys the lignins in wood, the "soft" polymers used in carpet backing, mattress padding, and destroys colors and dyes (starting with blue and heading for red last). So it is a beast best applied sparingly, and with foreknowledge of applied doses that are effective. It has some difficulty killing colony-forming organisms, and with organisms that have developed "slime formation" as a survival characteristic. As with ethylene oxide for sterilization, humidity and heat history prior to applying the steriliant (such as ozone) is important in limiting the amount and duration of sterilant required for kill.
