Clean & Disinfect a Humidifier

Step 1

Unplug your humidifier, then remove the filter (if your machine has one) and rinse it with cool water. Some chemicals can cause permanent damage to humidifier filters, so it’s best to clean it with water only. Set the clean filter on a towel and let it air dry, then replace it.Pour 1-2 cups of undiluted white vinegar into the water tank and swirl it around to wet the entire interior of the tank. Then replace the tank into the humidifier base, allowing vinegar to flow into the reservoir, and let your humidifier sit undisturbed for 15-20 minutes to break up any mineral buildup inside the machine.Pour the vinegar into a separate container (but don’t get rid of it just yet.) Use a small scrub brush or an old toothbrush to scrub cracks, crevices, and any stuck-on mineral deposits.Dip a cloth or sponge into the vinegar and use it to clean the small parts like the tank cap and the spout where the water vapor comes out. Make sure to rinse the tank and reservoir thoroughly, then proceed with the disinfecting process!

Step 2

Fill your humidifier’s tank with water, then add 1 teaspoon of bleach per gallon of water. If you prefer not to use bleach, pour 1-2 cups of standard 3% hydrogen peroxide into the tank.Swirl the bleach solution or peroxide around the tank to coat the inside evenly, then place the tank back into the base and allow it to sit for at least 30 minutes.Make sure to rinse the tank thoroughly afterward with clean water, and it’ll be ready to use again!
