Measurable aeroallergens found in dust from high-efficiency furnace filters

November 26, 2014

Significant levels of aeroallergens were measured in dust collected from high-efficiency furnace filters in the Midwest, according to recent study results.

Charles S. Barnes, PhD, section of allergy/immunology, Children’s Mercy Hospital, Kansas City, Mo., and colleagues studied allergen levels of dust taken from FQT12 1-inch disposable furnace filters with high-efficiency media placed in homes enrolled in the Kansas City Safe and Healthy Homes Project. Vacuuming was used to remove dust; fungal culture obtained viable spore counts. Commercially available immunoassay materials were used to measure aeroallergens Fel d1, Can f1, Mus m1, Der f1, Der p1 and Bla g2, and antigenic material from Alternaria, Aspergillus, Cladosporium and Penicillium species.
