Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 19.25x23.25x1 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 19.25x23.25x1 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.

19.25x23.25x1 Air Filter

Filter King 19.25x23.25x1 size air filters are placed in your home air systems to clean out incoming airflow free of harmful particles. Your home systems pump in air at a constant rate, with no real way of separating the clean air from the dirty. Your home’s indoor air quality drops when pollutants make their way inside, which is where air filters come in. The filters consist of a tight mesh weaving that traps and absorbs air particles over time. Your air filters become dirtier over time, and require frequent maintenance in order to avoid several problems from developing.

Your air filters keep incoming airflow clean, but as they become dirtier they start to cause problems themselves. Dirty air filters eventually become so covered in trapped and absorbed particles that airflow has trouble going through them. The lack of fresh air begins to affect your home as the air inside begins to dry out and stagnate over time. Your air systems also become forced to use more energy in an effort to push airflow past the blockage, causing a rise in electrical billing and leading to possible mechanical damages.

Your home benefits from having fresh airflow pumped in through clean filters that allow it to pass through naturally. Filter King offers fresh 19.25x23.25x1 size air filters to keep the filtration process going smoothly. We have a delivery service to have new filters delivered straight to your door. Orders of two or more filters are shipped for free. Our subscription option has new filters delivered as often as monthly. The filters themselves have a MERV (Minimum Efficiency Reporting Value) rating of eight, and block out irritants like:

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

19.25x23.25x1 Furnace Filters

Furnace air filters are tools required to keep heated airflow from polluting your air systems with irritants. Furnace air filters grow as dirty as any other and will eventually require replacement in order to avoid any temperature issues. Furnace filters handle heated airflow, which means that when the airflow is blocked it leads to problems throughout the system. New air filters will allow the airflow through and help you avoid unnecessary costs.
