Your heating system depends on furnace filters to keep dust and other impurities from interfering with the operation of your furnace or making your air smell dirty or musty. If your filters saturate too quickly or fail to effectively trap particles in the air, you could deal with problems such as:
- More frequent repairs on HVAC components
- Worsening respiratory problems or allergies
- Increased home heating costs
- Unpleasant odors from heat vents
If you have small children, pets, or senior citizens in your home, they might benefit from furnace filter replacement on a more frequent basis, such as once every 60 days.
