  • Title: Fungal colonization of air filters for use in heating, ventilating, and air conditioning (HVAC) systems.
    Author: Simmons RB, Crow SA.
    Journal: J Ind Microbiol; 1995 Jan; 14(1):41-5. PubMed ID: 7766066.
    Abstract:
    New and used cellulosic air filters for HVAC systems including those treated with antimicrobials were suspended in vessels with a range of relative humidities (55-99%) and containing non-sterile potting soil which stimulates fungal growth. Most filters yielded fungi prior to suspension in the chambers but only two of 14 nontreated filters demonstrated fungal colonization following use in HVAC systems. Filters treated with antimicrobials, particularly a phosphated amine complex, demonstrated markedly less fungal colonization than nontreated filters. In comparison with nontreated cellulosic filters, fungal colonization of antimicrobial-treated cellulosic filters was selective and delayed.
