Dry, cold winter air may lead you to consider running a humidifier. But if you have allergies, the device may not be the best choice.

The American Academy of Allergy Asthma and Immunology offers this advice:

• Running a humidifier may promote mold and dust growth.
• Dust mites, a common cause of allergies, thrive in humid environments.
• Maintain a humidity level of between 30 percent and 40 percent to reduce dust mites.
• Regularly change and clean the filter in your humidifier to prevent mold growth. Also regularly clean the humidifier itself.
• Use demineralized or distilled water in your humidifier, which will help lessen bacteria and dust.
