Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 30x30x1 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 30x30x1 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.

30x30x1 Air Filter

Filter King 30x30x1 size air filters keep airflow coming through your systems free of any harmful irritants from outside. The tight mesh weaving in your air filters is ergonomically designed to allow airflow to pass through while harmful irritants stay behind. The fresh air that enters cycles through your home and makes it easier to breathe inside. Indoor air quality rises, but the air filters become dirtier in the process.

Dirty air filters are a problem for their system and eventually for your home as a whole as airflow becomes blocked. When airflow is unable to pass through the filters in a system, then the home as a whole will begin to suffer from issues of dryness and stagnation. Your air systems become affected too, becoming strained as they try to push airflow through the blockage. Strained air systems are liable to suffer from mechanical damage over time and raise the energy billing for your home.

Filter King offers new, premium air filters that keep the airflow coming into your home without issue. We deliver our filters right to your door, with orders of two or more being delivered for free. We also have a subscription option to have your filters come in regularly to match your replacement schedule. Our air filters are capable of blocking out air particles like:

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

30x30x1 Furnace Air Filters

Furnace air filters work in your system to keep the airflow coming in clean after it becomes heated and before it becomes distributed. The air filters will need frequent replacement in order to prevent any issues with heating build up. If your filters are not replaced regularly, then that leads to a rise in temperatures that could end in mechanical issues. You will also face temperature fluctuations throughout your home since the rooms are not being heated by airflow. Avoid these problems by having new air filters installed and keeping the air coming in safe and clean.
