the functions of Humidifiers

A humidifier serves the purpose of adding moisture to the air in your room, thus increasing the humidity of the room. Generally, humidifiers are used during the winter season as the humidity stoops very low during those days.

A humidifier increases the level of humidity in the room with relatively low humidity by releasing moisture into the air. Humidifiers, thus, help in getting rid of several problems like dry nose, throat, and lips. In fact, it is helpful for patients with sinus too.

dehumidifier

What is the importance of Dehumidifiers?

Unlike humidifiers, dehumidifier functions by absorbing the extra moisture present in the air of your room, thus decreasing humidity. The moisture-laden air in your room once it enters the dehumidifier is sent out with a relatively less amount of moisture, as the dehumidifier absorbs the moisture from the air.

Generally, a dehumidifier cools down the air in your room before finally absorbing the excess moisture from it and then warming up the air. This process is called refrigeration. Other than refrigeration, dehumidifiers also use the absorption method where the moisture is first absorbed in a material and then the moisture-free air is released in the air of your room.

Some areas of benefit from dehumidifiers include: reduces allergies, helps in preventing asthma attacks, and decreases the risks of infections. 

Apart from these benefits, some disadvantages of dehumidifiers include the formation of molds and bacteria if not cleaning the dehumidifier and emptying its bucket on time. Excessive use of humidifiers is also not good for one’s health.
