Both dehumidifiers and humidifiers deal with humidity levels, but they do it in different ways. A humidifier adds water, or 'humidity', into the air, making it more moist. A humidifier blows introduces water vapours in the atmosphere by taking them from a water tank in the device. There are two types of humidifiers, the warm mist and the cool mist. The warm mist works by boiling the water to make steam that will be released in the room. This kind of humidifier is usually for point of use purposes. Cool mist however, works by allowing cold water to be absorbed by a wick. The wick allows the water to evaporate by using a fan resulting in a higher humidity.
A dehumidifier removes moisture from the air, making the air drier. A dehumidifier works by taking air from the room it is in and passing it through cold tubes. These tubes make air filled with moisture condense by forcing the moisture to collect on these cold tubes. The moisture collected is passed on to a container which holds the moisture. Once the container is filled the dehumidifier will turn off, stopping the moisture collected from overflowing the container.
How To Know Which To Use?
The Humidity level of the air in your house determines which appliance you need to use, either the dehumidifier or the humidifier. If your house has a humidity less than 30% you need a humidifier to increase the humidity levels so they are at a normal humidity level, if you house has a humidity more than 50% you need a dehumidifier to decrease the humidity levels so they are at a normal humidity When the humidity becomes less than 30% or higher 50% a humidifier or a dehumidifier are essential for safer living conditions.
