Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 19x25x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.


Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.


Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 19x25x1 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.

19x25x1 Air Filter

Filter King 19x25x1 size air filters are the tools used by your home air systems to clean up incoming airflow. The filters in a system consist of a tight mesh weaving that traps and absorbs particles out of passing airflow. The filters will work continuously, and are necessary considering air systems pump in air regardless to how clean it is. Your air filters will help raise indoor air quality, but become dirty over time. Dirty air filters are a problem for your home, and only create more issues over time.

Dirty air filters are the result of the particles trapped and absorbed over time building up and completely covering the filter. When this occurs, the filter is no longer able to effectively allow the passage of air into your home. Without fresh air to cycle into your home, the result is the air inside drying out and stagnating. Your home air systems also suffer as they use additional energy to try to push airflow through the blockage. Strained air systems may be mechanically damaged and cause a rise in energy billing over time.

Your home needs new air filters over time in order to avoid any problems with incoming airflow. Filter King offers 19x25x1 size air filters to fit into accompanying systems and clean up passing airflow. We ship orders of two or more filters for free, and have a subscription option to have new filters arrive at your home as often as monthly. Our air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight, and are capable of blocking particles like:

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

19x25x1 Furnace Filters

Furnace filters keep incoming airflow clean after it becomes heated and before its distribution. Your furnace filters cleanse airflow, and become dirty like they would in any other air system. Dirty furnace filters create a blockage that could have serious effects if not handled regularly. When the heated air is not released then it may lead to internal temperature problems and fluctuations. New air filters will help keep the airflow coming through naturally, so order today and have them delivered right to you.
