Denver’s cool, dry winters prompt many homeowners to opt for a whole-home humidification system to maintain comfortable indoor air. While these systems require less maintenance than portable units, it’s still important to change the humidifier pad to maintain good indoor air quality. Explore the basics of humidifier pad replacement, step-by-step instructions, and how High 5’s HVAC services can support your Denver home.

What Is a Humidifier Pad?

The humidifier pad is the component inside your whole-home humidifier that adds moisture to the air. When the humidistat detects low humidity levels, it signals the system to add moisture to the humidifier pad. The humidifier then blows air through the pad, allowing it to pick up moisture, which is then circulated throughout your home.

Signs It’s Time to Replace Your Humidifier Pad

It’s recommended to replace your humidifier pad at least once per season for optimal efficiency and indoor air quality. If you notice any of the following signs, it’s time to replace your humidifier pad.

White crust or mineral buildup on the pad

Your home’s water naturally contains minerals. As air moves through the humidifier pad, it picks up water but leaves the minerals behind. This results in a mineral buildup on the humidifier pad, typically appearing as a flaky, white crust.

While mineral buildup isn’t harmful, it does reduce your humidifier’s ability to moisturize your home. Change the humidifier pad when you start to notice a buildup, keeping in mind that you may need to do this more frequently if your Denver-area home has hard water.

Reduced humidity output

If your humidifier is struggling to humidify your home, it could be a sign of a clogged pad. The pad may no longer be able to effectively hold water, reducing the efficiency of your system.

Unpleasant odors

Damp spaces provide an environment for mold growth. If you start to notice a bad smell when you turn on your humidifier, this can indicate mold or mildew growth on the humidifier pad.

Discoloration or wear and tear

Visible signs of wear indicate that it’s time to switch your humidifier pad. If it becomes worn down, or if you notice brown, yellow, or other discoloration, consider changing the pad.

Tools and Materials Needed To Change a Humidifier Pad

Before you change the humidifier pad, make sure you have the following tools and materials:

  • A new pad that matches your system’s specifications
  • A gentle cleaning cloth
  • Vinegar and warm water solution

Wondering how to replace a humidifier pad? Follow these step-by-step instructions for a safe and easy change.

Step 1: Turn off the power to your humidifier or furnace

Step 2: Locate the humidifier access panel

Next, find the access panel for your humidifier and remove the cover. This may slide off, or it may be held in place with clips.

Step 4: Clean the humidifier housing

Using a gentle solution of water and vinegar, wipe down the humidifier housing. This helps clean and disinfect the area. Allow it to dry completely before inserting a new pad.

Step 5: Insert the new humidifier pad

Place a clean humidifier pad into the housing. It should slide easily into place and may have colors or arrows to indicate the correct position. Note that humidifier pads come in different shapes and sizes, so it’s important to buy the same one that you’ve removed.

Step 6: Reassemble the humidifier access panel

Replace the cover of your humidifier access panel.

Step 7: Turn the power back on

Once everything is back in place, turn the power back on and test your humidifier system.

Tips for Maintaining Your Humidifier Pad and System

Try these easy tips to maintain your humidifier pad and system for improved air quality and energy efficiency.

Check your humidifier pads monthly

Inspect your humidifier pads at least once a month to check for signs of wear, discoloration, or unpleasant odors. 

Practice annual HVAC maintenance

Benefits of Replacing Your Humidifier Pad

Discover why it’s important to maintain a humidifier pad replacement schedule.

Improved efficiency

Pushing air through a clogged filter requires your humidifier to use more energy, which can increase your utility bill. Clean filters enable smooth airflow, allowing your system to operate at maximum efficiency.

Longer system lifespan

When your humidifier has to fight to move air through a dirty filter, it wears down the motor and other components. Keeping the system clean makes it easier for your humidifier to run smoothly, prolonging the lifespan of the system. 

Better indoor air quality

An old humidifier filter can develop mold and mildew, which can then get circulated through your home. Changing the filter reduces the likelihood of unhealthy contaminants and keeps your indoor air clean.
