Tip

Remove the humidifier filter every week and a half. Place it in a bowl of white distilled vinegar and allow it to soak for at least an hour or even overnight. Squeeze out the excess vinegar. Replace the filter in the unit. It is vital to clean the humidifier twice a week. Empty the tank of any water. Wash it out with a cleaning cloth and hydrogen peroxide. Rinse the unit well before adding fresh water and vinegar.

Warning

Never store the humidifier with water in the tank. Empty, clean and rinse the unit, then dry it with a soft towel. This prevents mold and bacteria growth.

Vinegar helps maintain the health benefits of a humidifier.

Air in your home that is too dry may result in chapped lips, dry skin, nose bleeds or dry sinus cavities, according to the Mayo Clinic. The moist air from a humidifier helps prevent these issues and also soothe symptoms from respiratory problems such as a nagging cough. Adding a bit of vinegar to your humidifier is an effective way to reduce growth of bacteria that can result in foul odors and other health problems. Vinegar is also an effective way to disinfect the filter of this appliance.

Step 1

Dump out the water in your humidifier. Do this daily to prevent mineral deposits or bacteria growth.

Step 2

Add fresh water to the humidifier. Demineralized or distilled water is best for the appliance. It reduces mineral deposits and the white film that may develop on surfaces in your home. It also prevents breathing in the minerals.

Step 3

Pour 1/4 cup of white distilled vinegar into the water in the unit.
