What does an Air Purifier do?

An air purifier is a device whose main focus is to remove all the pollutants from the air and as a consequence improve the quality of air in your room. The air purifier is built with layers of filters that trap all the pollutants in the air and thus give back cleaned and purified air in the room.

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.

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.
