3 Things You Didn’t Know About Your Whole House Humidifier Filter

Continue reading to see why not changing your Whole House Humidifier Filter can be more detrimental to your furnace than not changing out your air filter.

We talk a lot here about the importance of changing out your furnace air filter. But did you know it’s just as important—if not more important—to replace the pad in your whole house humidifier? That’s right! Assuming you have an evaporative humidifier, which almost everyone does, that pad is regularly holding water and with Indiana’s hard water it takes a toll. If the pad isn’t changed regularly, it’s going to first cause your humidifier to not work effectively, then can cause even more damage to the electrical components of your furnace and A/C.

Here are three things you need to know about your whole house humidifier to ensure your furnace runs smoothly in your Indianapolis home throughout the winter months.

1. What is a Whole House Humidifier Pad

The humidifier pad—also know as a water panel, water pad, evaporator pad, or filter—holds and distributes moisture to the air passing through your furnace. When your whole house humidifier senses low humidity levels, more water gets added to the humidifier pad and passed to the air circulating throughout your house.

2. Why Your Humidifier Pad Must Be Regularly Replaced

No matter how soft your home water, some levels of scale, rust, and minerals build up on the metal honeycomb mesh of your humidifier pad. These deposits decrease the amount of moisture your whole house humidifier system can add to your Central Indiana home.

3. How to Change Your Whole House Humidifier Filter

Unlike the wide variety of furnace filter types and sizes, nearly all whole house humidifier pads come in the same size and type. To change out your old water panel, follow these steps:

• Turn off the power to your heating system via the fuse box.
• Take off the door cover from your whole house humidifier.
• Remove the entire humidifier filter, including the plastic frame, from the humidifier.
• Unclip one side of the plastic frame.
• Remove and discard the old humidifier filter.
• Slide in the new filter and reattached the plastic frame.
• Replace the frame assembly into the humidifier.
• Reattach the cover to your humidifier and turn the power back on.
