Why Buy Air Filters From Filter King?

In comparison to fiberglass filters, 13x20x1 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 13x20x1 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.
13x20x1 Air Filter
Filter King 13x20x1 size air filters act as valuable tools used by your home’s various air systems to clean up incoming airflow. When filtered, the airflow is freed of various pollutants and allergens that may have otherwise affected your home’s indoor air quality. The irritants in question become trapped in your air filters tight mesh weaving, which also allows airflow to travel through naturally. Over time, the captured particles begin to build and fill in the mesh weaving which creates a blockage in the air system.
When your air filters become a blockage, the resulting problems only grow worse the longer they go without replacement. One of the more common problems with dirty air filters is the resulting lack of air cycling in a home, leaving the old air inside to dry out and stagnate. Your air systems will try to bypass the blockage by increasing energy usage, but this will lead to an increase in electrical billing. Your air systems are also strained when their filters are dirty, which may cause them serious damage and require costly repairs.
New air filters are necessary to ensuring that the incoming airflow is cleaned before entering your home without problems. Our 13x20x1 size air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight. The rating indicates how effective our filters are at cleaning out incoming airflow. Some irritation our 13x20x1 size air filter is able to block include:
- Pollen
- Dust
- Mold
- Dust Mites
- Bacteria
- Pet Dander
- Smoke
- Viruses
