How to Clean Your Humidifier Reddit: The Ultimate Guide


Humidifiers are a popular household appliance that can help alleviate dry skin, congestion, and other respiratory problems. However, regular cleaning is essential to keep your humidifier functioning properly and prevent the buildup of bacteria and mold. In this guide, we’ll walk you through the step-by-step process of cleaning your humidifier, including tips for effective maintenance and troubleshooting common issues.

Step 1: Empty Your Humidifier

Before you start cleaning your humidifier, make sure to empty it completely. This will prevent any water from spilling during the cleaning process. Disconnect the power cord and unplug the machine from the outlet. If your humidifier has a removable tank, remove it and let it dry completely before proceeding.

Step 2: Clean the Tank

If your humidifier has a removable tank, start by removing any debris or buildup inside the tank using a brush or a small net. Rinse the tank with warm water and mild dish soap to remove any remaining dirt or grime. Be sure not to use too much soap, as this can damage the tank’s surface.

Step 3: Clean the Internal Filters

Most humidifiers come equipped with internal filters that help trap impurities and bacteria in the water. These filters should be cleaned regularly to ensure your humidifier is producing clean, fresh air. To clean the filters, simply rinse them with warm water and mild dish soap, then let them dry completely before reinserting them into the humidifier.

Step 4: Clean the Exterior of the Humidifier

The exterior of your humidifier may also accumulate dirt and grime over time. Use a soft-bristled brush or a damp cloth to gently clean the exterior of the humidifier, paying special attention to any crevices or hard-to-reach areas. Be sure not to use too much water or soap, as this can damage the machine’s surface.

Step 5: Disinfect the Humidifier

To kill any remaining bacteria and mold in your humidifier, it’s important to disinfect it regularly. One effective way to do this is by using a solution of half white vinegar and half water. Fill the tank with the solution, then run the machine on its highest setting for several hours. Afterward, drain the tank and rinse it with clean water before reusing it.

Step 6: Troubleshooting Common Issues

If you’re experiencing any issues with your humidifier, such as strange odors or a low output of mist, there are several troubleshooting steps you can take. First, check the filters and clean them if necessary. Next, ensure that the water in the tank is at the right temperature and level. If the problem persists, consult the manufacturer’s instructions or contact their customer service for further assistance.


By following these simple steps, you can effectively clean your humidifier and keep it functioning properly. Regular cleaning will not only improve the air quality in your home but also extend the lifespan of your humidifier.
