Humidifiers help in alleviating the symptoms associated with the common cold and allergies, and they make life much more comfortable for the afflicted.

But this only happens where the humidifier in question is in good condition. It is only then that one can look forward to such benefits.

Otherwise, you could be using your humidifier to expose you and your loved ones to health risks. The same humidifier that you rely on could easily be home to mold owing to the moist conditions it creates.

However, that does not have to be the case. With some maintenance work in place, you can ensure that your appliance is free of mold.

How does Mold Thrive?

It is well-known that moist and warm conditions provide an ideal growing space for mold. Thus, with water in the dish and heat from the motor, this is a perfect environment for mold. See how easy it is for it to grow?

Once the mold develops, it starts spreading throughout your home through the air. You soon begin to wonder why you keep getting sick with a fully functional humidifier running in the house.


You can inhibit the growth of mold in a few ways, thus ensuring that it does not harm you or your loved ones. The first thing you need to do is to clean the humidifier. Luckily, this is not a difficult task, and you can handle it as often as needed.

You can add it to your daily or weekly chores such that subsequent cleanups are more of a formality. In this way, the appliance can remain clean through the seasons.

When cleaning the humidifier, empty the water in it and dry it before adding clean water. Regularly doing this will ensure that bacteria and other microorganisms lack adequate time to grow. Where you periodically use the appliance, you can schedule the cleaning to once a week.

The environment in which you clean the humidifier affects the effectiveness of the cleaning. Suppose you do so in the presence of someone with lung issues or a mold allergy, the work will amount to naught.

That includes you too so be sure to get the appliance cleaned by someone without any health problems

You should use hot and soapy water to clean the tank before thoroughly rinsing off the soap. From here, add a cup of white vinegar to the tank as you fill the humidifier. Vinegar works as an antibacterial and antimicrobial agent.

It is an excellent choice as it will only work on the spores and will in no way harm the other parts of the appliance.

Where you do not have vinegar, you can use humidifier tablets. They work the same as vinegar. The only difference lies in the pricing in that the tablets will cost you more.

You could also add some supplements to the cleaning process. Examples include hydrogen peroxide, chlorine bleach, and tea tree oil. Be sure to note though that use of harsh substances works to deteriorate the hoses in the humidifier.

You will thus adversely affect the durability of the humidifier if you do this.

It also helps to use distilled water in the humidifier as tap water could have too many minerals. The continued use of water with minerals leads to a buildup which could make cleaning harder for you.

Finally, change the water daily as this will prevent the growth of microorganisms. They thrive in water that has sat for a while, and lack of this will keep them away.

All the best of luck in maintaining a mold-free environment!
