Contaminated air handling systems easily become breeding grounds for bacteria, mold and other sources of biological contaminants and can distribute these contaminants. By controlling the relative humidity level in a building, the growth of some sources of biologicals can be minimized. First identify and correct moisture problems. A relative humidity level of 30-50 percent is generally recommended for buildings. Water damaged materials, wet surfaces or standing water serve as breeding grounds for molds, mildews, bacteria and insects.
Dust mites live in rugs, carpets sheets, mattresses, pillows and upholstered furniture.
Mold and mildew originate from spores, which exist in the air around you. As spores settle with the right condition they form colonies, if enough colonies form they are visible to the eye. These colonies release spores and toxic chemicals called mycotoxins into the air. These biological contaminants can cause severe health problems and possible death. By controlling these contaminants you can reduce the likelihood of sick building syndrome and the health effects associated with it.
