What Is HVAC Biofilm? How It Forms, Why It Matters and How UVC Can Help

If you have ever looked inside a heat pump, air conditioning unit or commercial air-handling system, you may have noticed something that looks like a layer of dirt, slime or organic material building up around the coil or drain pan.It isn't always just dirt.In the right conditions, microorganisms can attach themselves to a surface and begin producing a protective matrix around themselves.This is known as biofilm.Biofilm is common throughout nature and can form on many surfaces where microor...

UVC vs Air Purifiers: Which Is Better For Your Home?
