But having the smart thermostat indicate it is time to change the humidifier pad can be troubling. Don’t worry! This is just a reminder that it is time to perform some easy maintenance. And with a little furnace repair in Los Gatos, CA you can keep your whole-home humidifier running safely and efficiently all year long.

What is the Humidifier Filter?

A whole-home humidifier does the important job of controlling moisture levels in the home. And once the installation is complete, homeowners will have the job of monitoring the humidifier filter. Other names for this part of your furnace are water filter, water panel, and evaporator pad. It might be better to think of it as a water retention pad. This essential part retains and dispenses moisture into the air as it progresses through the furnace. Basically, when the humidity control senses a drop in moisture levels the system causes water to flow through the pad to add more moisture to the air.

Why Do You Need to Change the Filter?

It is easy to see why this process can be problematic. The conditions are perfect for silt, mineral buildup, fungus, mildew, mold, etc. And the accumulation of this untreated dirt, debris, and decay can be problematic in a number of ways. A few issues might include clogged filters, insufficient humidity levels, higher energy costs, choked drains, and compromised air quality. These are the reasons why homeowners need to monitor their humidity filter and change it often.

How Often Should You Change the Humidifier Filter?

During installation, the HVAC technician should say how often homeowners should change the filters. Usually, once per year is sufficient to keep the system in working order. But during peak use, it might be necessary to change the filter more often. Other factors that can influence the frequency of filter changes include whether or not the occupants have allergies or pets. It might also be wise to consult the instruction manual that comes with the unit. This will give more details about the frequency of switching out filters.

How Do You Change the Filter?

First, shut off the power to the heating system at the fuse box. Then, take the door cover off the humidifier and remove the entire filter, including the plastic frame. Unclip the filter from the frame and discard it. Next, slide the new filter in place and reattach it to the frame. Replace the frame into the humidifier, reattach the cover, and turn the power back on.

What Happens if You Don’t Change Humidifier Filters?

Forgetting to swap out the filter can put unnecessary stress on the humidifier. The strain can cause the humidifier to be less effective so it no longer retains the desired humidity levels. A dirty filter can also lead to irritations and occupants might notice a sore throat, itchy eyes, dried-out phlegm membranes, or the sensation of dry skin.
