Regular duct, AHU and system cleaning only do part of the job. No amount of physical cleaning, vacuuming, brushing or washing can remove every contaminant, especially biological ones.
Without disinfection, cleaning alone only partially removes biological contaminants, like bacteria, viruses and mould/mildew.
GermXit® was developed by commercial heating, ventilation and air conditioning experts who knew they needed a safe, effective way to manage contaminants between cleanings.
