Relative humidity of 30 to 50% is recommended for good health. This is a challenge in extreme conditions, such as dry heat or too much humidity. A humidifier is used to increase the humidity level in the air and a dehumidifier reduces the humidity level of the air. A hygrometer can be used to measure the humidity of a particular area to decide if a humidifier or dehumidifier is needed.
How do you decide which one you need? A humidifier adds moisture to the air when it is too dry (below 35% humidity) and a dehumidifier removes moisture from the air when it is too humid (above 50% humidity). A humidifier is used to add moisture to dry air and a dehumidifier is used to remove moisture from the air. This is basically the main difference between the two. If the air in the room is too dry, a humidifier is used.
Dry air can cause nosebleeds, dry skin, sore throat and other infections. So it's always better to have a humidifier. In this list, we have chosen some of the best humidifiers you can buy, at a wide range of prices, for rooms of different sizes and for travel. Since each unit is different, be sure to check the specifications to find the specific operating temperature.
Rooms of different sizes and humidity levels may require dehumidifiers of different sizes to operate most efficiently. Read on to discover the difference between humidifiers and dehumidifiers, how they work, the different types available, and which one best suits your needs and the climate.
