How Filters Help Furnaces Work Optimally

Furnaces draw air in through the return register. This vent opening occupies a central location in your building and houses the furnace filter. When the indoor air handler sucks up air from inside, the air passes through the filter and into the return duct.

As you may have guessed, the filter cleans the air during every furnace operation. That’s how it prevents contaminants from building up in your breathing space and HVAC interior.

If you discover mold on furnace filters, you should immediately ask why there’s mold on your furnace filters. Otherwise, the mold will spread and lower everybody’s indoor air quality. 

A Few Reasons Why There’s Mold on Your Furnace Filters

Typically, mold prefers dark, damp spaces with little to no airflow. Why does it roost on your filter where air constantly passes through then? Common causes of mold on filters include the following:

• Too much airborne moisture: In Del Dios, California, humidity only goes down to about 64% in the driest month. At other times of the year, ample outdoor moisture finds its way inside and creates a conducive environment for mold. 
• Obfuscated airflow: If you leave a furnace filter in the return register for too long, the captured debris blocks the airflow. Less air pushing through that duct section might be why there’s mold on your furnace filters. 
• Active HVAC leaks: Ducts can sometimes develop excess condensation, which drips and trickles throughout the network. Mold loves a wet duct atmosphere. 

So, how do you solve the moldy furnace filter problem?

Once you know why there’s mold on your furnace filters, you can protect your system. One-on-one advice from a professional helps considerably. You can also prevent mold on furnace filters by:

1. Monitoring and managing indoor humidity: Purchase a hygrometer to measure moisture levels. Keep fresh air flowing in damp spaces like bathrooms. 
2. Routinely replacing your furnace filters: You shouldn’t keep a filter for longer than three months. Some lifestyles and indoor habits require more frequent replacements. 
3. Keeping your ducts squeaky clean: Book duct inspection every three years to address leaky materials, dust buildup, and excessive humidity. 
4. Implementing indoor air quality technology: Sometimes, you need a helping hand to get your air quality under control. Dehumidifiers, air purifiers, and ultraviolet lights eliminate allergens and moisture alongside your HVAC system.
