Why Buy Air Filters From Filter King?

In comparison to fiberglass filters, 11.25x19.25x1 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 11.25x19.25x1 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.
11.25x19.25x1 Air Filter
Filter King 11.25x19.25x1 air filters are used by air systems to create an active layer of protection for a home against incoming irritants. Your home may be in an environment with high levels of pollutants and allergens, the particles making the air unsafe and unhealthy to breathe. The indoor air quality of your home is dependent on how clean the incoming airflow is as it passes through your various air systems. Air filters keep this airflow clean, but in the process become dirty themselves as the captured particles begin to build up.
The air filters in your home become dirty over time, and in the process creates a blockage that creates problems for your home. When the airflow in a system becomes blocked, then that means that the old air inside your home is unable to cycle out. Old air needs to filter out of a home or it begins to dry out and stagnate. Air particles are also left floating around which makes breathing in a home uncomfortable and unsafe. New 11.25x19.25x1 air filters will provide fresh airflow, they also have a MERV (Minimum Efficiency Reporting Value) rating of eight. The filters are capable of blocking irritants like:
- Pollen
- Dust
- Mold
- Dust Mites
- Bacteria
- Pet Dander
