Please note that many variables take place in a real world environment that make actual calculating very difficult (air flow, humidity, distance of micro-organism to the UV light and time).   View Kill Chart link at the end of this introduction.

However, it is proven that UV light will kill any DNA-based organism given enough dosage and that UV light breaks down DNA over a cumulative basis.

Therefore, as air circulates through the ductwork of an HVAC system containing a UV light, like the SafeGuard UV Cleanser, the UV light continuously cleanses the air. If a micro-organism is not effectively eradicated on the first pass through the ductwork, the UV light will continue to break its DNA down on subsequent passes.

In addition, micro-organisms typically do not sit in a static environment in HVAC systems except on coils which can be exposed to our lights. In fact, micro-organisms breed micro-organisms if not controlled. The UV light process helps to reduce the incidence of inhaled exposure of microorganisms in persons who reside or work in buildings with UV light air cleansing systems.
