This post will teach you just that. So let’s get started.

What Causes Mold to Grow in Humidifiers?

Before we get into how to keep mold out of your humidifier, it’s important to understand why mold grows in humidifiers in the first place.

The warm and moist environment that the humidifier creates is an actually ideal condition for fungi or mold to grow.

Especially if you live in a cold area or a place where the temperature fluctuates, then mold can grow inside your humidifier.

The water you use can also contribute to the problem of mold inside your humidifier.

Tap water has so many kinds of bacteria and other microorganisms.

If you use tap water without filtering it, these bacteria and fungus can get inside your humidifier tank.

The water in your humidifier tank can soon become a breeding ground for mold and germs if you don’t change it regularly.

That is why it is recommended to use distilled water so that you can prevent mold from growing inside your humidifier.

Now you know why mold can grow inside your humidifier, let’s get into how to prevent mold from growing inside it.

Cleaning your humidifier might sound like a simple task.

One solution is to leave vinegar inside the water tank for few hours so that all those microorganisms will die.

Another way to clean it is using a water and dish detergent mixture.

By blending the two together, you can create an effective solution to clean your humidifier tank.
