How To Clean A HoMedics Humidifier?  [A Step-By-Step Guide]

HoMedics is a famous brand selling home health innovations, and their humidifiers are called totalcomfort humidifiers. While you can reap a lot of benefits by using Homedicis humidifiers, you have to commit to regular cleaning as well. 

I am a HoMedics humidifier owner and really like their products. Yes, I have to clean and maintain it every few days, but the cleaning process only takes a few minutes. So don’t be stressed about it. 

By following this guide, I am sure you will understand how to clean your HoMedics humidifier properly.

Step 1: Unplug your HoMedics Totalcomfort humidifier

Since humidifiers are electronic gadgets, you have to disconnect them from the outlet before doing any cleaning task. No one wants to fall prey to an electrical shock.

Step 2: Move the machine to the sink and pour out all the water     

Some HoMedics humidifiers can produce warm mist, like my totalcomfort deluxe one, a warm/cool mist humidifier. In this case, I suggest you wait a few minutes until the water cools down to ambient temperature before moving to the sink to avoid burns.  

By lifting the water tank, you will be able to remove it from the main unit. Then just unscrew the tank cap, and all water will drain into the sink.

After that, you need to dump the water from the humidifier base.

Step 3: Clean water tank

The water tank and base of a humidifier are great places for mold and fungus growth because it is warm and damp. Meanwhile, the dissolved minerals will gradually turn to mineral deposits, which can clog the machine and expel white dust into the air.

To solve these issues with your HoMedics humidifier, you need to change the water every day and clean it every three days. 

Even if the water tank is not empty, you have to dump all the remaining water and rinse the tank and tank tap before refilling because the standing water contains a lot of impurities, which will continue to contaminate the newly added water.

If you have a demineralization cartridge added, you should also remember to rinse it off with clean water.

To deep clean the water tank, you have to use a solution of white vinegar and lukewarm water with a 1-to-1 ratio. Pour 1 cup or 2 cups of this mixture into the tank and let it sit for 1 to 2 hours. 

If you find any stubborn mineral deposits, you can immerse a soft cloth into the mixture and give the tank a good scour.

The water tank of most HoMedics humidifiers is transparent, so it is easy for you to tell if it is clean. Once it is clean, you have to rinse off all the remaining solutions until it doesn’t smell like vinegar. 

Step 4: Clean transducer/ultrasonic membrane

The transducer and ultrasonic membrane are critical parts of any humidifier. Some HoMedics humidifiers come with a specific door to protect them, and others don’t. 

You have to keep it clean because the machine will stop working whenever it is clogged. 

Note that you can’t touch it with your fingertips or hands as the oils can ruin it. It is also why you can’t add any essential oil to a HoMedics humidifier. 

Apply the solution of vinegar and water we just made to a cotton swab and use the cotton swab to wipe off the deposits on the membrane. 

Step 5: Clean the base of your HoMedics humidifier

As the proportion of water will get into the base from the water tank, the base is also a place that needs to be cleaned and sanitized regularly.

You need to rinse the base every day when you change the water. Furthermore, you can also use the vinegar and water solution to disinfect it every few days. Unlike disinfecting the tank, you can let the solution sit in it for 1 to 2 hours.

Use a soft brush or a soft cloth to wipe off any solid impurities left in the base, and then rinse off with water.

Step 6: Clean the surface 

The surface can get stains and dust on it over time. Use a soft, damp cloth to wipe it off to clean it. If some stains are hard to remove, you can use some gentle cleanser. 

Step 7: Air dry

You can let each part air dry before refilling if you have enough time. This is even important when you plan to put it away when summer is coming. The moisture left inside will foster the growth of microorganisms, which will pose risks to the humidifier and you.


As a HoMedics humidifier owner, I have to say cleaning it is effortless. While cleaning and maintaining a humidifier can take you some time, there is no complicated step involved in this process. 

There are a few things you should keep in mind. Firstly, you have to rinse off and refill the water tank every day since the mold spores, bacteria, and other impurities will grow rapidly in the stagnant water. Secondly, you can’t use your hands to touch the ultrasonic membrane when cleaning. At last, you have to dry off each part for storing it in the cabinet. 

If you want to reduce the frequency of cleaning, you can add distilled water to the water tank or use a demineralization cartridge.
