Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 28x30x1 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 28x30x1 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.

28x30x1 Air Filter

Filter King 28x30x1 size air filters are used in a variety of different air systems as important tools that keep incoming airflow safe and clean. The filtration process keeps the airflow coming in smooth and clean, raising your homes overall air quality. The filters in your systems consist of a tight mesh weaving that is capable of capturing and absorbing irritants out of passing airflow. The process is necessary, but requires fresh air filters since the old become dirtier over time and cause problems for your home.

Air filters only grow dirtier over time, leading to issues for the system they are in and eventually your home. Airflow is unable to pass through dirty air filters effectively, which leads to problems of dryness and stagnation throughout. The air quality will dip and your systems will try to compensate by increasing their efforts to push airflow forward. This causes a strain on the system which may lead to mechanical damage over time. The strain also leads to a rise in electricity usage that raises your home energy billing.

Filter King 28x30x1 size air filters are available for purchase and capable of installation upon arrival. Your orders of two or more filters are shipped for free, and regularly if you choose our subscription option. Our filters rate as an eight on the MERV scale, which means that they are capable blocking out particles like:

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

28x30x1 Furnace Air Filters

The furnace filters in your home keep heated airflow clean as it comes in through your systems and into your home. The air coming in is heated and when a dirty furnace filter blocks it that heat begins to build up over time. If new filters are not installed regularly, then there will be issues with the temperature that may cause mechanical damage.

Your home will also begin to experience temperature fluctuations as the heating is unable to reach your rooms. The energy billing will also become raised as the system struggles to push airflow forward. Avoid these problems by having new air filters installed and keeping heated airflow clean as it passes through.
