Rationale Controlling indoor fungal allergens has become an increasing concern for individuals with allergies and asthma, so we collected data to assess the impact of education and cleaning on indoor airborne fungal spore levels. Methods Families with at least 1 child were recruited and were provided with specific education on sources of indoor allergens and cleaning practices. They were supplied with cleaning products containing sodium hypochlorite and instructed on their use. Three visits at one-month intervals were conducted to collect airborne spores. Non-viable spores were collected using an Allergenco MK3 spore trap and enumerated as spores per cubic meter of air. Viable spores were collected using an SKC Biostage onto an agar plate and enumerated as CFU per cubic meter of air. Statistical tests for differences between the before and after treatment groups were performed assuming a log normal distribution. Results 180 homes were visited 3 times each during the study for airborne spore analysis. The geometric mean for viable spores before treatment was 251 compared to 216 after treatment (p
