What is a humidifier?

When we use the term humidifier we refer to the devices used to keep the best humidity levels indoors, no matter how hot, or cold it is outside. The difference between this device and an air conditioning system is that this last one can cause the environment to dry out.

There is a certain percentage of humidity that should be in the air we breathe, and it ranges between 30% to 50%. It is impossible to expect the normal air to guarantee these quantities, so that is when humidifiers enter.

There are several types of humidifiers, but they all work under the same principle: they take some water placed in a reservoir and then move it out into the air in a vapor form. Let’s take a look at the different types of humidifiers.
