How Often to Change Your 16.25x21x1 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.

16.25x21x1 Air Filter

Filter King 16.25x21x1 size air filters are made of a tight mesh weaving designed to keep indoor air quality up and irritants out. Air filtration is a necessary part of any system, used to keep the airflow coming in free of harmful particles. If the airflow is not cleaned up, then there is no telling what sort of pollutants and allergens are capable of entering your home via airflow. The air filters keep the incoming air clean, but become dirtier and less effective over time.

The air filters in your systems are important, but they do not last forever, they will eventually require replacement. Air systems with dirty air filters will eventually become problems that affect your home as a whole. Your air systems are unable to fully process airflow, forcing the system to use more energy in an attempt to bypass the blockage. The spike in energy usage pushes your air systems to dangerous degrees and may lead to higher billing and possible mechanical damage.

Your air systems benefit from having new filters installed, allowing for fresh air to pass through into your home without issue. Filter King offers new 16.25x21x1 size air filters at affordable rates to make regular filter replacement easier to maintain. Our air filters also have a MERV (Minimum Efficiency Reporting Value) rating of eight. With a rating like that, the air filters are capable of blocking out irritants like:

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