Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 19x20x1 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 19x20x1 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.

19x20x1 Air Filter

Filter King 19x20x1 size air filters are tools your home air systems use to keep incoming airflow clean before they enter your duct system. The air filters in your home consist of a tight mesh weaving that allows airflow to pass through while irritants are captured. The process is necessary to keeping indoor air quality from dropping over time. Your air filters will continue to clean out airflow until they become covered in captured particles, which leads to them become less effective over time.

The air filters in your home do not remain clean forever, they eventually become dirtier over time. When the air filters in your home become dirty they are less effective and cause issues throughout their systems and your home. The air already inside your home is unable to cycle out without fresh airflow, leading to problems of dryness and stagnation. Your air filters are also strained when forced to try to push airflow past the blockages, leading to mechanical issues.

Dirty air filters cost your home over time as expensive repair costs and increasing energy billing begins to rise over time. We offer new 19x20x1 size air filter replacements along with a delivery service to have them shipped to you as well. Our subscription option provides the opportunity to have new air filters shipped out as often as monthly. The filters have a MERV (Minimum Efficiency Reporting Value) rating that shows their effectiveness at blocking out irritants. Filter King air filters have a MERV rating of eight and blocks out a range of particles including:

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

Filter King air filters are also capable of fitting into a variety of different air systems, furnace systems included. Your furnace filters are capable of cleaning heated airflow before they dirty air has a chance to pollute your home. The furnace filters become dirtier in the process and eventually create a blockage. A furnace blockage is dangerous, leading to temperature fluctuations and a rise in temperatures for the system. The issues inevitably lead to costly repairs for the system that may have otherwise been avoided with air filter maintenance.
