In this study, a questionnaire survey was conducted to assess the status of air purifier and humidifier installation at kindergartens and nurseries in the Hokuriku region as countermeasure against influenza. In this region, 64% of the facilities, lower than that in the Tokai region, installed at least one equipment affecting the indoor air environment. The proportion of the installation of these equipment was higher at nurseries than at kindergartens. Window opening ventilation was the most widely adopted preventive measure against infection, and the use of air purifiers and humidifiers may influence the indoor environment only slightly.
