Ultraviolet Disinfection (UVC) Systems

UVC Disinfection is the only tried and true method of killing off bacteria, viruses, mold and fungus in air and water.

With bacteria developing resistance to antibiotics at an alarming rate, and the increase of nomocosial (hospital-acquired) infections, there has never been a better time to evaluation your HVAC sanitation system.

MonMan performs microbial contamination studies for our clients, include air pressure changes (through coils), mold & bacteria samples (species and colony counts), and time lapse photography for visual verification of improvement.

We all want our needs to be met with an unique solution. Our solution, not Pete’s, Jill’s or Steve’s.
