Insufficient or high moisture levels in the home lead to discomfort and adversely affects our health and well-being. Humidity, along with temperature, significantly impacts the comfort and air quality inside a house. 

Maintaining the right humidity levels or relative humidity is essential for maximum comfort. The humidity level between 30% and 50% is considered ideal for maintaining good health and ensuring a comfortable indoor environment. Any levels above or below this range cause issues. 

Humidifiers and dehumidifiers are devices used to regulate the humidity levels in a residential or commercial setting. While both the units work to control moisture in the air, they are not similar and serve different purposes. 

Let’s understand the difference between a humidifier and a dehumidifier to determine which one is ideal for a home or business:


A humidifier increases the moisture levels in the air to get rid of the dryness for improved comfort. They are ideal for rooms or areas that are too dry. Humidifiers are more useful in winters to combat the aridity in colder months. Low humidity is associated with skin dryness, nasal bleeding, sore throat, irritation, headache, and increased risk of respiratory illnesses. Humidifiers alleviate allergy symptoms, prevent nasal congestion, and get rid of dryness to ensure healthy skin.


Consider getting a humidifier if the home lacks sufficient insulation or if the family frequently experiences static shocks, nosebleeds, chapped lips, dryness, and itchiness, the furnace fails to warm the home despite correct thermostat settings, and there are cracks and gaps in wooden furniture, flooring, and molding.

Warm-mist and cool-mist are the two main types of humidifiers available in the market. 


Dehumidifiers perform the exact opposite job. They remove the excess moisture from the air to keep it dry when the relative humidity goes above 50%. People usually need dehumidifiers during the warmer months, when the air is hot and humid, or control humidity in areas with little or no ventilation. Excessive moisture can cause several problems and health issues such as heat stroke, heat exhaustion, dehydration, insufficient indoor air quality, mold, mildew, dust mite growth, or damage to the furniture, walls, and other belongings. Excessive humidity may also trigger asthma symptoms. Dehumidifiers control the relative humidity to improve indoor air quality and prevent mold growth. 

There are four types of dehumidifiers to choose from—electronic, refrigerative, desiccant, and ionic. 


Choose portable units if the humidity levels are not too high or low, and there is a need to humidify or dehumidify only a few areas. However, these are less effective and more difficult to maintain. 

A whole-house unit is installed directly with the existing HVAC system to offer consistent humidity levels in the house. They are more powerful, energy-efficient, and simple to maintain. 

A homeowner may require a humidifier, dehumidifier, or both, depending on the area’s moisture levels throughout the year. Contact an HVAC service to know whether the home needs a humidifier or a dehumidifier and which one will work best to keep the house healthy and comfortable.
