How Often to Change Your 20x23x1 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.

20x23x1 Air Filter

Filter King 20x23x1 size pleated air filters are important parts of your home air systems, protecting against incoming irritants. Your pleated air filters are in constant use as the systems keep pumping in the fresh air. The cleaned air raises indoor air quality and makes the air inside your home safer to breathe as a result. Your pleated air filters become dirtier in the cleaning process, eventually leading to problems for your home. The air filter needs regular replacement in order to avoid several issues from developing over time.

The pleated air filters in your home will become dirty, and afterward, they will start causing issues for their systems and your home. Dirty air filters are unable to properly allow the passage of airflow. The resulting lack of fresh air in a home leads to dry and stagnant air, which is both unhealthy and uncomfortable to breathe. Your air systems will try to push fresh airflow into your home past the blockages. The attempt uses additional energy and will cause your systems to suffer mechanical damage and your home to face a rise in energy billing over time.

The air filters in your home need maintenance in order to keep airflow coming in smoothly and help improve the indoor air quality. Filter King offers fresh 20x23x1 size pleated air filters capable of being used as soon as they arrive. We provide a delivery service, along with a subscription option, where orders of two or more pleated air filters are shipped for free. Our pleated air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight, eleven, thirteen and block airborne particles including:

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

20x23x1 Furnace Filters

Furnace filters are used in their system to keep heated airflow clean before its distribution into your home. Your furnace pleated air filters will keep most of the pollutants out of your systems depending on what MERV rating (minimum efficiency reporting value) they have, but they require maintenance before becoming dirty and a problem. Dirty furnace filters block heated airflow, which leads to a temperature buildup over time. If the problem is not fixed, then your home will suffer from temperature fluctuations and the furnace may face mechanical damage. Choose your correct filter size for the HVAC unit from our range of air filter sizes and order today. Keep incoming airflow clean and free of irritants.
