21x23.25x1 Air Filter

Filter King 21x23.25x1 size air filters are valuable tools used to keep the air coming into your home clean. Our air filters are ergonomically designed to keep airflow coming through clean of any airborne irritants. The tight mesh weaving is loose enough to allow the process to continue until the filter is completely covered in particles. You need to swap out these dirty air filters for new ones, before they start causing several problems throughout your home.

The air system in your home only grow dirtier over time as they continue to become covered in captured particles. The filters become so dirty that they become unable to properly process any incoming airflow. Without fresh air, your home will begin to suffer from dryness and stagnation over time. Your air systems will try to push the airflow through the blockage but that may result in further problems. The systems become strained and use more energy as they increase their efforts, possibly leading to mechanical damage and an increase in billing over time.

The air filters in your home need frequent replacement if the air is to remain comfortable to breathe in. Filter King is ready and able to deliver fresh new 21x23.25x1 size air filters to your home. Orders of two or more filters are shipped for free and delivered regularly if you use our subscription option. The filters we provide have a MERV (Minimum Efficiency Reporting Value) rating of eight and block out particles like:

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

21x23.25x1 Furnace Filters

The air filters in your home are usable for a variety of systems including your furnace systems. The furnace filters clean out incoming airflow and make sure that the heated air is not bringing any harmful particles. The filters become dirtier over time and require replacement, or they cause temperature problems throughout the system. The heated airflow is stopped and begins to build up which eventually causes mechanical damage. Order new air filters today and ensure your home’s heated airflow enters without any issues.
