According to estimates, concerns about the quality of indoor air may be present in as many as 30% of buildings globally. Both organic and inorganic particles are potential air pollution sources. This article focuses on biological air pollutants originating from living and non-living organisms, particularly those related to fungi. Domestic house indoor air contains fungi that, to a significant extent, share the same species composition as those outside the building. When rooms are ventilated or through other openings, microorganisms enter buildings where they can grow on the surfaces of a variety of materials. Intensely grows in stuffy, humid, poorly ventilated areas. For this reason, residents may experience more discomfort from exposure to interior air pollution than they would from exposure to outside air contaminants. Due to their propensity to produce mycotoxins, allergic reactions, volatile organic chemicals, and even fungal illnesses, fungi can be extremely dangerous when found in residential buildings.
