Why Buy Air Filters From Filter King?

How Often to Change Your 12x30.5x1 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.

12x30.5x1 Air Filter

Filter King 12x30.5x1 size air filters keep incoming airflow clean, at the same time they also help prevent problems for a home’s indoor air quality. Your air filters are tools made of a tight mesh weaving that traps and absorbs particles passing by on pumped in airflow. Filtration is required for an air system to bring in air and not have it negatively impact your home. Your air filters will continue to clean up incoming air, but they will eventually require replacement as the particles begin to build up.

When the air filters in your home become dirty then the resulting complications become worse over time. Air is unable to cycle through dirty air filters, causing the air inside your home to dry out and stagnate. The air systems will also try to bypass the blockages your air filters become by increasing their energy usage. The resulting spike in electricity use leads to a rise in energy billing and an increased strain on your air systems. These complications can lead to billing amounting to thousands of dollars in avoidable costs annually.

New air filters allow air to pass through them naturally, which gives the home fresh air to cycle through its ducts and rooms. Our filters are capable of blocking out a wide range of irritants as well. The 12x30.5x1 size air filters rank as an eight on the MERV (Minimum Efficiency Reporting Value) scale. With that ranking, the new filters are capable of blocking out irritants like:

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