How Often to Change Your 25x28x1 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.

25x28x1 Air Filter

Filter King 25x28x1 size air filters are used by the air systems throughout your home to keep incoming airflow clean. The air systems in your home are not able to bring in purely clean air, they may bring in any pollutants surrounding your home. Filters are able to help by cleaning out incoming airflow and preventing irritants from polluting the air inside. The process raises indoor air quality over time but the filters grow dirtier the longer they are left in a system.

Dirty air filters are the result of particles completely covering them over time as the tight mesh weaving continues to trap and absorb them. When the particles build up to a problematic degree, then airflow is not able to pass through into your home. The resulting lack of fresh air ends up causing dryness and stagnation throughout your home. Your air systems also suffer as they try to push airflow through the blockage. The resulting effort may lead to mechanical damage as the systems are pushed to their limits. Your energy billing also rises as they systems increase their electricity usage.

We deliver orders of two or more filters for free, and offer a subscription option to have your air filters delivered as often as monthly. Our air filters are rated on the MERV scale, which lets you know just how effective they are at cleaning up incoming airflow.

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

25x28x1 Furnace Air Filters

The furnace filters in a system are used to keep incoming heated airflow clean as it comes through the system. When furnace filters become dirty, then that leads to heating problems as the temperatures start to rise. The heat continues to build up until there is mechanical damage or temperature fluctuations throughout your home. Order new filters today and keep the airflow coming in without issue when you replace them regularly.
