How Do Furnace Filters Become Clogged?
All furnaces utilize filters that are designed to keep your home’s indoor air quality as high as possible. Furnace filters pull contaminants, such as dirt, dust, pet dander, debris, and other particles, from your air supply before they’re passed through your ductwork and into your home, helping you breathe higher-quality air.
As your furnace filters collect these particles, the filter will naturally become clogged. Regularly replacing your furnace filters is an important step to take in keeping your furnace running properly.
Signs That Your Furnace Filter is Clogged
Spotting a clogged filter is crucial for maintaining your furnace’s efficiency and preventing potential issues. Here’s how to tell if your filter needs attention:
- Visual Inspection: Take out the filter and inspect it visually. If it appears gray or dirty, it’s likely clogged and needs replacement.
- Airflow Reduction: Reduced airflow from vents could signal a clogged filter. If rooms are taking longer to heat or cool, it might be due to restricted airflow.
- Increased Energy Bills: A clogged filter forces the HVAC system to work harder, consuming more energy. A sudden spike in energy bills could indicate a clogged filter.
Issues Caused by Clogged Furnace Filters
If your furnace filters are clogged, you’ll likely start noticing issues related to your home comfort or air quality. Some problems caused by clogged furnace filters include:
- Reduced Efficiency: A clogged filter impedes airflow, forcing the furnace to work harder, reducing its efficiency, and potentially shortening its lifespan.
- Poor Indoor Air Quality: Accumulated dust and allergens circulate back into the air, worsening indoor air quality, which can trigger allergies or respiratory issues.
- System Damage: If left unaddressed, restricted airflow can cause the furnace to overheat, leading to potential damage to its components.
How Often Should You Replace Your Furnace Filter?
How often you should change your furnace filter will depend on a variety of factors, including how often you use your furnace, the type of filter that your furnace uses, and the furnace manufacturer’s recommendations.
For example, Basic fiberglass filters might need replacement every 1-3 months, while higher-grade filters may last up to 6-12 months.
However, as a general rule of thumb, be sure to check your filters monthly and replace them when visibly dirty. Homes with pets or with residents prone to allergies may need to change their furnace filters more frequently.
