Why Buy Air Filters From Filter King?

Image

In comparison to fiberglass filters, 23.5x23.5x1n pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Image

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.

Image

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 23.5x23.5x1n 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.

23.5x23.5x1 Air Filter

Filter King 23.5x23.5x1 size air filters are tools used by your air systems as a way to clean out airflow as it pumps inside. Your air systems are not capable of telling the good air from the bad, so the filters clean incoming airflow free of irritants. The filters consist of a tight mesh weaving that allows airflow to pass through without issue but capture and absorb any irritants. The resulting air is clean enough to make your home comfortable and will lack any harmful particles. However, the air filters in your system become dirtier in the process and less effective over time.

Dirty air filters are the result of the tools being left for too long in the system and becoming completely covered in irritants. These blockages affect the system when they stop allowing airflow to pass through without issue. Without fresh air, your home will suffer from issues of dryness and stagnation over time. Your air systems will also become strained over time as they attempt to try to push airflow past the blockage. The resulting efforts will use more electricity over time and this leads to a rise in energy billing over time.

Your home needs new air filters to come in periodically or the issues with the air system spread out throughout your home. Filter King offers new 23.5x23.5x1 size air filters designed to keep the airflow coming in clean. We deliver them right to your door, with orders of two or more filters being shipped for free. We also have a subscription service to have new air filters brought in periodically. Our filters have a MERV rating of eight and block out particles like:

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

23.5x23.5x1 Furnace Air Filters

The furnace filters in your air system will keep the heated air coming in clean before distribution into your home. These filters will eventually become dirty and that leads to temperature problems for their system. The heat in the system will continue to rise until it is unable to handle the heat and suffers from mechanical damage. Your home will suffer from temperature fluctuations as well. Order new air filters today and keep the airflow coming in clean as you swap them out frequently.
