Why Buy Air Filters From Filter King?

Image

In comparison to fiberglass filters, 19.88x21.5x1 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 19.88x21.5x1 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.

19.88x21.5x1 Air Filter

Filter King 19.88x21.5x1 size air filters are important parts of any given air system, ensuring air comes in fresh and clean. The air filters are ergonomically designed to allow airflow to pass through while allergens and irritants are captured in a tight mesh weave. When filters are not used, indoor air quality is affected as the particles begin to pollute the air throughout your home. The air filters in a system will keep passing airflow clean, but become dirtier in the process. Over time, the filters become so dirty that they block out airflow and create problems throughout your home.

Your air filters only grow dirtier over time, the mesh weaving will eventually become completely covered in irritants. When air systems have dirty air filters then the resulting issues affect your home as a whole. Fresh air is unable to travel through dirty air filters, leading to problems with stagnation and dryness. Your air systems are also strained when they have to push airflow through dirty filters.

Strained air systems are more likely to suffer from mechanical damage over time, they also use more energy which causes billing to rise. New air filters will allow airflow to pass through clean and without issues. We offer replacement 19.88x21.5x1 size air filters to help keep the air coming into your home clean. Filter King also has delivery services, with a delivery option to have new air filters shipped regularly. Our filters come with a MERV (Minimum Efficiency Reporting Value) rating that displays their effectiveness at blocking out irritants. The filters we provide block out particles like:

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