How Do Whole-Home Humidifiers Work?

A whole-home humidifier is installed into your HVAC system‘s ductwork and works with your furnace during colder months to add moisture to the air.

It’s connected to your home water supply and contains a heating element and water reservoir. A vapor forms as the unit heats and the water evaporates.

The moisture is transferred to the furnace’s heated air, raising the humidity level before the warm air is distributed throughout your home.

Benefits of Installing a Whole-Home Humidifier

Boosting the moisture inside your home is particularly useful in the winter, as it helps:

  • Reduce dry, cracked skin: Maintaining a more balanced indoor humidity level can help soothe and prevent the discomfort of itchy, flaky skin.
  • Make it harder for bacteria and viruses to spread: Higher humidity levels can reduce the ability of flu viruses to survive on surfaces and in the air, potentially lowering the risk of sickness.
  • Lower energy bills: Moist air feels warmer than dry air, which can help you feel comfortable at lower thermostat settings, ultimately reducing heating costs during the winter.

What’s the Ideal Humidity Level?

Experts recommend an indoor humidity level between 30% and 50%. There are risks of having lower or higher humidity:

  • High indoor humidity provides an ideal environment for mold and mildew to thrive, which can lead to structural damage and health issues like allergies and respiratory problems. It also attracts pets and can warp wood, peel paint, and cause wallpaper to bubble.
  • Low indoor humidity can cause or worsen sore throats, sinus headaches, and dry skin. It can also increase static electricity and cause wood furniture and flooring to shrink and crack.

Frequently Asked Questions

Is it worth getting a whole-house humidifier?

Yes. Investing in a whole-house humidifier can significantly improve indoor air quality and comfort, particularly in dry climates and during cold seasons when heating systems make indoor air drier.

Should a whole-house humidifier run all the time?

No, a whole-house humidifier should not run continuously. It’s most effective when operated with a hygrometer, which helps maintain optimal humidity levels, prevent excess moisture, and reduce energy waste.

What’s the life expectancy of a whole-house humidifier?

A well-maintained whole-house humidifier typically lasts between 10 and 15 years.

How often do I have to replace a furnace humidifier filter?

You should replace a furnace humidifier filter annually, ideally at the start of the heating season, to ensure efficient operation and prevent mineral buildup.

Do whole-home humidifiers cause mold?

Whole-home humidifiers that aren’t properly maintained are at increased risk of mold growth. You can prevent this by regularly maintaining the system and monitoring humidity levels to stay within a healthy range.

What are the pros and cons of different types of furnace humidifiers?

Drum humidifiers are economical and easy to install but require frequent maintenance and pose a higher risk of mold.

Flow-through humidifiers require less maintenance and do not have standing water. However, they use more water and can be more costly to install.

Steam humidifiers work independently of the furnace and are the most effective, but they use more energy and have higher upfront costs.
