How Often to Change Your 12x18x1 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.

12x18x1 Air Filter

Filter King 12x18x1 size air filters are necessary parts to an air system to keep airflow coming into a home clean and clear of irritants. The air systems in your home require filters or the air they bring in may not be the cleanest. Air filtration is particularly necessary for homes in areas with high levels of pollutants or allergens. Your air filters are able to keep your home’s indoor air quality from dropping while cleaning the incoming airflow. Your air filters will become dirty in the process and require replacement, or the ensuing problems only become worse over time.

When the air filters in your home become dirty then the resulting problems only become worse as the particles build up. Your air filters consist of a tight mesh weaving that captures and absorbs passing irritants when they become dirty the ensuing blockage affects incoming airflow. When airflow is hindered or stopped, the old air inside is unable to cycle out leading to stagnation and dryness. The lack of airflow also causes the system to compensate, which increases energy billing and strain on the systems.

New air filters will help prevent many air system issues and keep the airflow coming in smoothly without a problem.
