Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 27x27x1 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 27x27x1 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.

27x27x1 Air Filter

Filter King 27x27x1 size air filters are used in a variety of different air systems as tools that keep incoming airflow clean. Filtration is necessary since it allows fresh airflow to come in while keeping harmful irritants out. The clean air is then able to enter your home and cycle out the old air, raising your home’s air quality over time. Your air filters consist of a tight mesh weaving that allows for effective filtration, but they grow dirtier over time. When the air filters in your systems become too dirty, they become an issue for their system and your home as a whole.

As air filters become more and more covered in captured particles, they begin to lose their effectiveness over time. When air filters become too dirty, they are unable to allow airflow to pass through effectively. The lack of fresh air will cause dryness and stagnation throughout your home over time. Your air systems will try to push the airflow through the systems but this will end up straining the systems over time. Strained systems are liable to require mechanical repairs and additional energy billing over time.

Filter King offers new, replacement 27x27x1 size air filters that are capable of installation upon delivery to your home. Orders of two or more filters are shipped out for free, with regular shipping schedules available with our subscription option. All air filters are ranked on the MERV scale to show how effective they are at bringing in fresh airflow. Filter King air filters rank as an eight on the MERV scale and block out irritants like:

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

27x27x1 Furnace Air Filters

The furnace air filters in your systems keep heated airflow coming in clean as it is pumped in by the system. Furnace air filters become dirtier over time and when they become too covered in irritants they are unable to allow airflow to pass through easily. When heated airflow builds up, then the resulting rise in temperature will cause issues for the system. You may need to pay off expensive repair costs and additional energy billing over time. Your home will also suffer from temperature issues since the warm airflow is unable to enter the rooms inside. Order new air filters today and keep incoming airflow clean and smoothly cycling through your home.
