The Recalls.gov database lists 10 product recalls related to humidifiers since 1977. As of 2015, the most recent humidifier recall concerns a potential fire hazard caused by Ultrasonic Clean Mist humidifiers manufactured by Great Innovations.
Recalls.gov compiles product recalls from six federal agencies into a searchable database. This database includes recall information on products that are manufactured or sold in the United States. The primary agency responsible for consumer products, such as humidifiers, is the Consumer Product Safety Commission.
Products bought outside of the United States and brought into the country by individuals can be checked against the Organization for Economic Cooperation and Development global recalls database. The OECD aggregates worldwide recall information from member institutions, including product safety agencies in Mexico, Canada, Australia and the European Union.
