What is an evaporative humidifier anyway? 

A humidifier is also known as a wick humidifier. Just like any other humidifier, an evaporative humidifier also does the following:

  • It helps to add moisture in the air and helps to increase the levels of humidity in the air.
  • It can help to reduce the effects of dry air on your skin as well as on your overall health.

How are evaporative humidifiers different from other humidifiers? 

One of the main features that make an evaporative humidifier different from any other type of humidifier is the fact that it uses a fan as well as a wick filter to work.

Owing to the way that it is built and the kind of mechanisms that it has, an evaporative humidifier works a little differently as compared to some other types of humidifiers. Here are a few ways in which it works differently than the other types:

  • The evaporative humidifier has an internal fan that helps it to pull the air inside it.
  • Once the air gets inside the device, it moves through a water saturated wick filter. This filter absorbs the water that is present in the reservoir in the device, and the air passes through it.
  • As a result, some amount of this moisture also gets absorbed by the air that passes through the filter.
  • This same air is then thrown out into the air and it helps to maintain the required amount of humidity levels in the room.

How Evaporative Humidifiers Work

Here is a more detailed look at how an evaporative works and what are some of the different parts that it has:

An evaporative humidifier is actually one of the simplest types of humidifier and has very few necessary components that make it work, which are the reservoir, the fan and the wick.

Here is a look at the way it functions:

  • 1
    The fan and the wick filter are the two main components in an evaporative humidifier that make it work the way it does.
  • 2
    The wick in the evaporative humidifier uses a cloth or a paper sheet that lets it soak up the water that is stored in the reservoir or the basin of the device.
  • 3
    Once the fan in device is switched on, it starts blowing out the air towards the wick.
  • 4
    As a result, the water starts to evaporate and a fine mist gets created, which then gets released into the air where the evaporative humidifier is placed.
  • 5
    Once the moisture gets created, the humidifier helps to extract any heat that is present in the air around.
  • 6
    The water then starts to reduce the amount of heat that is present in the air around, and once that starts to happen, it also helps to bring down the temperature that is there in the room where the evaporative humidifier is placed.

Are evaporative humidifiers more popular than other types of humidifiers?

With more and more people understanding the importance of a humidifier, there are a host of different variants available in the market today. An evaporative humidifier is gaining popularity these days, as there are quite a few benefits to it, starting from the cost factor to how it can be used and cleaned and more. It is also one of the more common types of humidifiers that people use.

 Evaporative Humidifier
Pros and Cons

Here are 3 pros and cons of an evaporative humidifier:


1. It's one of the simplest types of humidifier:

  • Since an evaporative humidifier has mainly three components that help it do what it does, it is one of the simplest types of humidifiers that you can use.
  • It is also great for those who are going to use a humidifier for the first time, as you will not have to worry too much about cleaning and maintaining it.

2. It costs less as compared to other types:

  • When you buy an evaporative humidifier, the cost will be much lesser as compared to the other types of humidifiers.
  • This also makes it a good option if you are buying a humidifier for the first time and don’t want to end up spending too much on one, or if you are planning to use it for a few years and don’t intend to use it for many years at a stretch.

3. It will not discharge a dusty mist in the air:

  • When you use hard water, evaporative humidifier won’t dispel any dusty or greyish particles in the air and the room will look clean instead of looking dusty.
  • When you use hard water in other humidifiers, they create a greyish dust that spreads in the room. As a result, the room in which you will be using this type of a humidifier could look dusty.


1. It's noisier than other types of humidifiers:

  • An evaporative humidifier is noisier than other types of humidifier.
  • If you’re using it for a baby room or for a place you want to be absolutely quiet, this may not be the best choice.

2. The cost may increase in the future

  • An evaporative humidifier costs less than the other types but this could be a problem later.
  • The filter in the evaporative humidifier has to be replaced after the first few years, unlike others.

3. The simple design may not always be competitive moving forward

  • One of the things that may not work entirely in favour of an evaporative humidifier is its design.
  • While the other types are sleeker and can fit in with most home décor, the evaporative type is not as stylish.

Is this the best type of humidifier out there? Why or why not?

The evaporative humidifier is definitely the simpler of the lot, in terms of the way it works as well as in terms of maintenance. If you are planning to use this for a few years only, or want to try out one for the first time, this could make a good choice. But if you want this specifically for baby’s sleep time, the sound may be a bother and you may do better with an ultrasonic humidifier instead.
