Commercial HVAC System Contamination (Biofilm, Humidifier Lung, Legionella, Cooling Towers) — household safety profile
Moderate riskCommercial HVAC systems can become reservoirs for biological and chemical contaminants.
What is this product?
Commercial HVAC systems can become reservoirs for biological and chemical contaminants. Cooling coil biofilm: condensate on cooling coils supports bacterial and fungal growth (Aspergillus, Cladosporium) — distributed throughout building via ductwork. Humidifier fever/lung: hypersensitivity pneumonitis from contaminated humidification systems. Cooling towers: Legionella pneumophila colonization — Legionnaires' disease outbreaks traced to commercial cooling towers (NYC 2015: 138 cases, 16 deaths from South Bronx cooling towers). ASHRAE Standard 188: Legionella water management program required for buildings with cooling towers, whirlpool spas, decorative fountains, or complex plumbing.
