Shock Pro-QTZ. This ozone generator is efficient at producing ozone in humid conditions because it uses quartz tube cooling technology to produce ozone with fewer byproducts in adverse conditions, leaving contents scent-free and with no chemical residue. Ozone is effective after flooding because it attacks and oxidizes mold, spores and mildew that starts to form in wet conditions, allowing materials time to dry out before significant mold can colonize.
