Material Compatibility with Ozone

Using ozone for periodic shock treatments or for mold and smoke remediation should not cause concern with materials damage. 

The ozone materials compatibility chart is for choosing ozone room construction materials / seals, or for industrial uses where constant concentrated high levels of ozone will be used.
