The people who use humidifiers often ask about how to clean humidifiers. Cleaning a humidifier is very important because, after a certain time, it might start creating molds that will affect your life quality and health.

Therefore, it is recommended to clean the air humidifier in your house frequently, at least once a week. If any of your family members suffers from respiratory disease, cleaning the humidifier more frequently is important.

This article is the ultimate guide on how to clean a humidifier and a list of humidifier cleaners that will help you in this process. We have provided you with a step-to-step guide on cleaning humidifiers that is extremely convenient.

Things that you will need

Below is the list of things that you will need for cleaning the humidifier. For how to clean a humidifier, you will need the below-mentioned elements that are easily available and might already be at your home;

  • A soft brush (make sure not to use hard abrasive brushes)
  • Chlorine bleach (liquid)
  • White vinegar (distilled)

Step-by-step humidifier cleaning guide

Below, we have assembled a step-by-step guide on how to clean a humidifier, and let's dig into the guide without wasting any time.

  1. The very first step done to clean the humidifier is to unplug it and then empty it. To empty the remaining water, make sure to follow the instructions provided by the manufacturer. This is important to avoid water contact to any other part of the humidifier, especially the motor.

  2. Now for the tank or base of your humidifier, you don't want any detergent or anything. This element is readily available in your kitchen cabinet. Take a measuring cup and add a good amount of full one to two measuring cups of distilled and undiluted white vinegar in the tank. Make sure that the vinegar wets all the base area. White vinegar is a very effective humidifier cleaner, and when left on a surface for a while, it helps take out all the moulds and contaminants easily.

  3. Let the distilled white vinegar drain into the reservoir and sit there for about twenty minutes. This white vinegar will trigger the mineral build-up, and it will eventually loosen up.

  4. After you have let the white vinegar set onto the base surface for a good twenty minutes, now is the time that you empty the tank of your humidifier. When the tank is empty of the white vinegar, take a soft brush and scrub off the stubborn mineral build-up particles. Make sure not to scratch the surface hard to avoid any scratches on the surface.

  5. Now, you have your tank and base all cleared and clean. Take a cloth and soak it with clean water; use this cloth to clean all the residues from the base.

  6. Now take a cloth and soak it in high-strength white vinegar; clean the smaller parts of the humidifier, too, including the cap of the tank.

  7. After all the cleaning, rinse the humidifier thoroughly as instructed by the manufacturer, ensuring that water doesn't enter the electronic parts or components of the humidifier.

  8. The last step is to dry the humidifier before reassembling it into its original working form.

Washing the wick filter is not recommended at any cause and should be replaced when necessary. This is because when the filter is washed, it can damage the antimicrobial coating and the paper-like materials of the humidifier.
