Why Buy Air Filters From Filter King?

How Often to Change Your 15x20x1 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.

15x20x1 Air Filter

Filter King 15x20x1 size air filters are necessary parts of an air conditioner system used to make sure incoming air does not negatively impact your home’s indoor air quality. Your air filters are capable of blocking out harmful particles by capturing them in a tight mesh weaving. The harmful irritants capable of affecting the air inside your home become blocked, while clean air enters. The fresh air cycles into a home, while the old air is cycled out, but the air filters become dirtier over time.

Over time, the air filters in your air conditioner systems become dirty as they constantly clean all the incoming air being pumped inside. Your dirty filter will continue to clean out the air until they become completely covered in the trapped and absorbed particles. Dirty air filters are unable to efficiently bring air flow into an HVAC system, which may lead to several problems with the air inside of your home. Old air needs to cycle out of a room or ducts, or the results include drying out stagnation, and temperature fluctuations.

Your dirty filter also puts an increased strain on their HVAC system that may cause mechanical damage over time. New 15x20x1 size air filters will help you avoid several air problems by allowing air flow to pass through into your home clean and clear of irritants. Our air filters have a MERV rating (Minimum Efficiency Reporting Value) of eight, eleven or thirteen, and are capable of blocking out irritants like:

  • Pollen
  • Household Dust
  • Mold Spores
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Viruses
  • Tobacco Smoke
