Humidifiers are great for restoring moisture into dry air and can help in so many ways, but if your humidifier isn't clean, it can also disperse germs and bacteria into the air without your even realizing it.


How often should you clean your humidifier? At least once per week when being used regularly, and then one more time before putting away in storage. Here are easy steps on how you can clean and disinfect a humidifier.

Things You'll Need

  • 2 tablespoons of distilled white vinegar

  • 1/2 gallon of warm water

  • Microfiber cloth

TIP: It is best to use distilled water in your humidifier. Tap water can contain mineral deposits that can cause build-up over time that promote bacteria growth and can deter the humidifier from working properly


Step 1: Clean the water tank.

To begin, unplug the humidifier and remove the water tank. Add the vinegar and warm water to the water tank and allow it to sit in the tank for at least 30 minutes. After 30 minutes, cover the opening and shake the solution in the tank. Rinse with warm water and dry using a microfiber cloth.

Step 2: Clean the water basin.

Use the same steps as above, allowing the vinegar and water solution to sit in the water basin for at least 30 minutes before shaking well and drying with a microfiber cloth.


Step 3: Clean the outside of the humidifier.

Use a mixture of equal parts distilled white vinegar and warm water to clean the outside of the humidifier. Spray or moisten a clean cloth with the vinegar mixture and thoroughly wipe down the outside of the humidifier, including any air vents and crevices.
