What can I do if the HERTSMI score is too high? The most effective method for decontaminate an indoor environment is a combination of hydroxyl generator, proper vacuuming, a thorough interior flush, and wiping all large, horizonal surfaces with our botanical disinfectant. Contact your engineer for the full details on how to effectively decontaminate an indoor environment.
