How Often to Change Your 29.75x31.75x1 Air Filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.

Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.

Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.

You should change your filter more frequently if you notice:

  • Household dust build-up
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Higher energy bills
  • Burning smells near your HVAC system.

29.75x31.75x1 Air Filter

The filtered air is then cycled throughout your home and will help raise the air quality throughout.

The irritants that would have polluted your home are prevented entry, but the air filters become dirtier in the process.

Air filters for your home systems become dirty, it's an inevitable fact that leads to frequent replacement for the tools. When the air filters are clean, airflow is able to pass through without issue and raise the air quality of your home.
