Why Buy Air Filters From Filter King?

How Often to Change Your 11.5x11.5x1 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.

11.5x11.5x1 Air Filter

Filter King 11.5x11.5x1 air filters are important tools needed to keep air systems clean and your home safe. Your air filters consist of a tight mesh weaving that captures airborne irritants out of passing airflow. The cleaned air that enters a home is able to cycle out the old air and which provides the home with a fresh, clean smell. Your air filters become dirty in the cleaning process and will eventually require replacement to avoid any issues with indoor air quality.

When the air filters in your home become dirty then the resulting issues with the air in your home only grow worse over time. New air is unable to travel easily through dirty air filters, and that means the old air cannot cycle out. Old air is not comfortable or healthy to breathe, it dries out and stagnates over time. Dirty air filters are also a strain on whatever air system they are installed in, which increases wear down and raises energy costs. New air filters allow airflow to pass by easily, and with a MERV (Minimum Efficiency Reporting Value) rating of eight, also block out irritants like:

  • Pollen
  • Dust
  • Mold
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Smoke
  • Viruses
