While adding humidity to the air may be beneficial, too much humidity can cause more problems. High humidity levels can worsen respiratory problems and create an uncomfortable dampness in the air, which can encourage:
- dust mites
- mildew
- mold
- harmful bacteria
Humidifier therapy provides real relief for some individuals. However, these devices can also cause problems when they are not used correctly.
Special care should be taken in households with children. Never let children handle humidifiers, and don’t place a warm-mist steamer in a child’s bedroom.
Burns are the most common injuries associated with humidifiers.
Allowing a unit to expel too much moisture can create condensation on the walls. This water can then turn into mold and spread throughout the home.
Unclean humidifiers can cause bacterial growth that can promote
coughs and colds. Follow the manufacturer’s instructions and clean the unit regularly to prevent bacterial growth. Steam vaporizers can get dirty quickly, but they are also among the easiest to clean. Rinse out all used water between uses. Additionally, be sure to wash the bucket and filter system every two to three days during usage.
Humidifiers can potentially emit minerals and microorganisms in the air. Although not necessarily harmful, the residue can bother asthmatics. The Environmental Protection Agency (EPA) recommends using distilled water to avoid this problem.
Call your doctor if your medical symptoms don’t improve. If your symptoms worsen with humidifiers, stop use entirely and contact your physician.
