The primary function of a Air Purifier or Humidifier is to increase the moisture content in a confined space like a room or workspace. By releasing water vapor or steam, humidifiers combat dry air, which is common during winter or in dry climates. This added moisture can relieve various discomforts, such as dry skin, chapped lips, static electricity, and respiratory problems. Maintaining an optimal indoor humidity level of 30% to 50% creates a more comfortable environment. Additionally, humidifiers can help reduce the spread of germs and illnesses and alleviate symptoms of colds and the flu, particularly by easing nasal congestion.
