HVAC systems are described as both a risk for distributing contaminants and an opportunity for filtering them. Common MERV 8 to MERV 12 filters may be insufficient for very small mold, bacterial, or toxin-associated particles. Contaminated coils or ducts can redistribute particles throughout a house. Evaporator coils are a mold and bacteria concern because they are wet by design. MERV 16 filtration is presented as a high-efficiency option, but usually requires a properly installed system rather than a simple replacement filter. A restrictive filter can impair HVAC performance by increasing pressure drop.
