How Often to Change Your 18x25x1 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.

18x25x1 Air Filter

Filter King 18x25x1 size air filters are vital parts of your air systems, used to keep incoming airflow free of harmful particles. Air filtration is an important process that prevents outside irritants from polluting your home. Your home’s indoor air quality benefits from cleaner airflow, making it safer and more comfortable over time. You will need fresh new air filters to help ensure that the airflow coming into your home continues to become clean over time.

The air quality is dependent on your air filters, mainly their ability to clean incoming airflow as well as allowing it to pass. Over time, the incoming airflow will begin to cover your filters in a layer of captured allergens and pollutants. The dirty air filters are unable to properly process incoming airflow, which is a problem for their systems and your home as a whole. Air systems with a blockage have difficulties that end up costing a home with expensive repairs and increased billing.

The air filters in your home require consistent maintenance in order to maintain functionality and effectiveness.

18x25x1 Air Filter Delivery

The furnace filters in your home keep airflow coming through the system clean, but require consistent maintenance. Your furnace filters go in between where incoming airflow becomes heated and the blower fan that distributes it throughout your home. Dirty air filters stop this airflow from traveling, which leads to large temperature problems in the system and throughout your home.
