5.7 Maintenance

5.7.0 Cleaning of Humidifiers and Related Equipment

Humidifiers, dehumidifiers, and air-handling equipment that involve water should be cleaned and disinfected according to manufacturers’ instructions.
These appliances provide comfort by controlling the amount of moisture in the indoor air. To get the most benefit, the facility should follow all instructions. If the facility does not follow recommended care and maintenance guidelines, microorganisms may be able to grow in the water and become airborne, which may lead to respiratory problems (1).
For additional information, contact the U.S. Consumer Product Safety Commission (CPSC) and the Association of Home Appliance Manufacturers (AHAM).
