Basic approaches to control indoor air pollution include source control, source isolation, increased ventilation, dehumidification, and the use of filters (see the table). Possible sources of contamination are eliminated in a source-control strategy. Examples include banning smoking in public buildings, using carefully selected building materials to avoid the emission of toxic or irritating substances, and limiting the use of fibrous materials. Source-isolation strategy is used in situations where a source cannot be completely eliminated. For instance, copy machine areas, food service stations, and bathrooms are often separately vented outside buildings to avoid the recirculation of return air. Existing sources of pollution such as leaded paint and asbestos insulation may either be removed or encapsulated. Increased ventilation and filtration are traditional approaches to ensuring good indoor air quality. Dehumidification helps in the reduction of microbial growth. Low humidity should be maintained inside a house to limit the growth of such bacteria.
