Humidifiers vs. Dehumidifiers

It’s not always easy to control air quality in your home when it comes to how much moisture is in the air at any given time. With situations of this nature, you may need either a humidifier or dehumidifier to fine-tune your indoor air quality. Below, we go over the differences between humidifiers and dehumidifiers and the benefits associated with each option.

Indoor Air Quality - Humidifiers vs dehumidifiers


A humidifier adds moisture to the air in your home. Some homeowners in Illinois use humidifiers during the winter months when indoor air is more likely to be drier. This can happen from the increased usage of a furnace or other heating system. When you throw in the fact that more people spend time indoors during the winter months, it’s easy to see why dry air can make a home uncomfortable.

A humidifier may be beneficial for any of the following reasons:

  • Dry air causes nose bleeds on a recurring basis
  • A lack of sufficient humidity is contributing to snoring or similar sleep problems
  • Dry air is aggregating your sinuses

Dry indoor air also has the potential to affect your home structurally. For instance, leather furniture may be more susceptible to cracking in a home that’s lacking sufficient humidity. Even your indoor plants can be impacted by air that’s too dry.

Humidifier - Indoor Air Quality


A dehumidifier, on the other hand, removes moisture from the air in your home. It’s more common for dehumidifiers to be used during warmer months of the year throughout Illinois.

A dehumidifier is often beneficial in instances when:

  • You have people in your household with seasonal allergies
  • Your current cooling system isn’t fully removing all excess humidity from your indoor air
  • You or someone in your household has health issues affected by excess humidity

Too much moisture could also contribute to problems with mold and mildew in your home. Additionally, you may feel uncomfortable relaxing in your home due to high humidity levels even if you have an air conditioner running.

What’s Right for Your Home?

Typically, humidity levels in a home should be somewhere between 30 and 50 percent when levels are within an acceptable range. Use this average to determine what you need. If humidity levels are over 50 percent, for instance, a dehumidifier is what’s needed. On the other hand, if levels are below 30 percent, a humidifier is worth considering. Humidifiers and dehumidifiers can be standalone units used in specific rooms or whole-house systems that manage moisture levels throughout all your living spaces.

How a Professional HVAC Company Can Help

Illinois has what’s referred to as a continental climate. In other words, winters are usually cold and summers are often warm – and sometimes humid. In fact, it’s not unusual for temperatures to fluctuate throughout the year in this area. For this reason, there may be times when your indoor air quality is affected in some way. What a professional HVAC company can do is help you find effective ways to manage humidity based on your comfort needs.
