Why Buy Air Filters From Filter King?

How Often to Change Your 23x25x1 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.

23x25x1 Air Filter

Filter King 23x25x1 size air filters are tools that keep the airflow coming into your air systems clean and free of irritants. The filters in your systems consist of a tight mesh weaving that allows airflow to pass through while preventing any harmful particles from polluting your home. The air that comes in will cycle through the various rooms in your home and raise air quality. As the air in your home becomes more safe and comfortable to breathe in, the air filters in your systems grow dirtier.

Dirty air filters are a problem for your home due to the fact that they are unable to allow airflow to properly pass through. Without fresh air, then the rooms throughout your home will experience dryness and stagnation over time. Your air systems will try to push airflow past the blockage and into your home, but they become strained in the process. The effort also uses additional electricity, which leads to a rise in billing over time.
