How to clean a humidifier

Sep 18, 2020

Replacing the moisture in your home is important when you’re battling respiratory colds, but don’t forget to clean and sanitize that humidifier. After all, what good is a humidifier to your health if it’s blasting moldy moisture into your home?

What you need to do to clean a humidifier at home.

Begin by unplugging your humidifier and emptying all remaining water. Stagnant water is what leads to mold and bacteria, and you’ll need to empty it in order to disinfect the unit. Be sure to follow the manufacturer's instructions when you pour water out of the appliance in order to avoid moisture entering the motor and electrical components in the base. Allowing water to enter is an easy way to break your humidifier.

If you reach into the reservoir or touch the base of the machine that was filled with water and it feels a little greasy or grimy, that’s a sure sign you’ve waited too long to clean it. But never fear, that’s the grime we’re here to conquer.

Unplugged, fill the base of the humidifier with 1 cup of water and 1 cup of white vinegar and leave it to sit for an hour. The vinegar is a natural cleanser and it’ll help loosen any residue and disinfect the small unit.

While the base of the humidifier is being treated with the water/vinegar solution, take the time to clean the inside of the water reservoir. Because the water sits stagnant in that container, the interior of the reservoir will also develop a greasy film. The best way to clean it naturally is to fill it with 2 cups of pure white vinegar, seal it shut, and then shake-shake-shake to effectively agitate any grime. Do this for several minutes — or as long as your arm muscles will tolerate the workout.

Hold the reservoir upside down and manually allow the vinegar solution to filter through the nozzle of the reservoir. This is often done by pressing on the nozzle to loosen the seal.

Once emptied, refill the reservoir with plain water, and repeat to rinse any loosened debris from the reservoir and the nozzle.

Once the base has soaked, pour the solution out (again, making sure you empty properly so that the liquid doesn’t enter the motor). Use a vinegar-soaked cloth to wipe down the interior of the base and then allow it to air dry.

Use the same cloth to clean the exterior components of the small appliance, such as the funnel that air travels through.

Cleaning the humidifier routinely will help to keep mold and bacteria at bay, which in turn keeps the mist produced by the humidifier clean when being used in your room. Think clean and be healthy!
