Biofilm forms when bacteria and other microorganisms stick to surfaces and begin to reproduce, typically in moist environments found in your HVAC system (drain pans and coils). This growing mass of biofilm can release bioaerosols and volatile organic compounds (VOCs) which can then begin circulating through your ventilation, leading to poor indoor air quality, potential health issues for the occupants, and even sick building syndrome (for more on this subject, read PetVet Magazine’s “Sick Building, Sick Business: How Indoor Air Quality Affects the Financial Health of Your Business”).
Aerapy Animal Health’s UV systems for HVAC can help eliminate biofilm.
