How Often to Change Your 19.25x21.25x1 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.

19.25x21.25x1 Air Filter

Filter King 19.25x21.25x1 size air filters are important tools used by your home air systems to clean out airflow. Fresh air is necessary to keeping your home clean, which in turn makes it more comfortable and safe to live in. The blocked irritants include a wide range of allergens and pollutants capable of polluting your home air systems and lowering indoor air quality. The filters in a system continue to protect your home, but will eventually become covered in irritants and unable to allow airflow to properly pass through.

As the air filters in your home become dirtier over time they are unable to allow airflow to pass through into your home. The lack of incoming airflow means that the air inside your home is unable to cycle out and become fresh. Your home will suffer from issues of dryness and stagnation without any fresh airflow. Your air systems will also become increasingly strained as they try to pump air flow through the dirty air filters. The strain will lead to costs including those for repairs and gradually rising energy billing.

The dirty air filters in your air systems need replacement before they cause increasingly problematic issues for your home. Filter King 19.25x21.25x1 size air filters are available to help you maintain the air quality in your home. We also offer a delivery service to have the filters delivered right to your home, along with a subscription service where new air filters are shipped regularly. The filters themselves have a MERV (Minimum Efficiency Reporting Value) rating that shows their how effective they are at blocking out irritants. Filter King air filters have a MERV rating of eight, showing their ability to block out irritants like:

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

19.25x21.25x1 Air Filter Delivery

Filter King air filters are capable of fitting into your furnace systems and keeping the incoming heated airflow clean. The filters go in between where the air becomes heated and where it distributes into your home. As the filter becomes dirtier the heated airflow is unable to travel through the air system. Blocked heated airflow causes serious issues for your home and leads to mechanical damage and temperature fluctuations throughout the home. Order new air filters to help prevent these issues and ensure clean airflow for your home.
