Our today’s topic is Humidifier vs Dehumidifier. But before getting into the topic I would like to briefly introduce you all to both the terms: Humidifiers and Dehumidifiers. So that you can understand the difference between them well.

What is a Humidifier?

A humidifier is a device that helps in increasing the moisture level of the air. A Humidifier constantly emits water vapour in the form of steam in the air with the help of a water tank situated in the base area inside the humidifier. This way the humidifier decreases the dryness of air which helps in preventing irritation, itchiness and dryness of the skin. It increases the moisture in the air.

Different types of humidifiers are available in the Indian Market. Some of them are given below:-

  • Ultrasonic Humidifiers
  • Central Humidifiers
  • Evaporators
  • Steam Vaporizer Humidifiers

What is a Dehumidifier?

A dehumidifier is a device that helps reduce the humidity level of air. The working of a dehumidifier is totally the opposite of a humidifier. The dehumidifiers extract all the water from the air present in the room. Generally, this device is used in commercial buildings such as swimming pools and storage warehouses. The dehumidifiers help in preventing the growth of any infectious disease or mould which generally grows on walls and ceilings due to the presence of heavy moisture in that area.

Humidifier and Dehumidifier explanation

A humidifier and a dehumidifier both are used to perform different jobs. 

A humidifier adds moisture to the air whereas a dehumidifier extracts extra moisture from the air. 

As humidifiers add moisture to the air that’s why we generally use them in the winter season because most of us feel some kind of dryness and dehydration in that season. It helps prevent that feeling. 

Contrary to that a dehumidifier takes out extra moisture from the air that’s why we use this tool in June July to prevent dampness and growth of any kind of lethal infection. These months are considered too hot. Though, it is mentioned in most of the places that too much heat with high moisture is very dangerous for our health.  

A dehumidifier also helps in excluding bad odour caused due to bacteria which rises because of an increase in the moisture.

Which one should I buy? 

If you are keen to buy a humidifier or maybe a dehumidifier for your home then first of all you need to give some attention to the current weather and moisture level of your home. 

You can also call an Indoor Air Quality (IAQ) specialist for assistance. He will help you to check the best air quality for your home. 

Also, there are some tools in the market to help in examining the humidity level of rooms. One of them is a hygrometer. A hygrometer helps in measuring the humidity level (water vapour) present in the air. You can purchase these kinds of instruments online at an affordable price of 15 to 20 thousand.

In normal conditions, the humidity levels between 30% to 50% are considered quite perfect. If your room’s humidity level is lower than 30% then you should buy a humidifier or if the humidity level is greater than 50% then you should definitely need a dehumidifier.

How does humidity affect health? 

Humidity affects our health and body in different ways. Right now we will discuss some of the major issues that most of us face when the humidity is too low or too high.

Winter itch

This is the most common problem we face in the winter season known as the winter itch. Due to less humidity present in the air, our body feels dry and itchy. This is because cold waves can’t store much humidity. That’s why it tries to absorb the required humidity from our body. This can be felt more on the soft parts of the body.


Hyperthermia is a problem that occurs due to the high humidity levels present in the environment. This can make our body unable to release heat which can cause some of the organs and brain damage. You can also feel low energy and lethargy if your environment holds too much humidity. 

Increased risks of cold and flu

Can you believe low humidity can affect your body so much that it gets prone to these common diseases such as cold and flu? Most of the viruses have a greater chance of existence in less humidity. That’s how too little humidity can also impact health negatively.


As you can see there are some serious health hazards of too much and too little humidity. In this article, we give our best to introduce you all to these serious health issues which can be caused due to inappropriate humidity levels in your surroundings.
