How Often to Change Your 14x25x1 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.

14x25x1 Air Filter

When an air system needs protection, then a filter installation is necessary to prevent dust and debris issues from overwhelming the system. HVAC and furnace systems alike use 14x25x1 air filter size air filters as valuable barriers between your home and the outdoors. Air passing through filtration has any accompanying particles trapped and absorbed in the tight mesh weaving. Over time, the stopped particles will begin to build up and fill in the mesh’s open spaces until the filter becomes a blockage. Air filter maintenance is important to ensure that the problems that come with dirty filters do not severely harm your home.

14x25x1 Air Filter Use for Residential Homes

The indoor air quality of the average residential home depends on a steady cycle of fresh, incoming airflow. The new air comes in, replaces the old, and this repeats until the filter is too dirty to continue. When the filter is dirty, then that causes the incoming airflow to stop, which blocks out ant fresh air along with pollutants and allergens. Your home without active airflow becomes uncomfortable as the air stagnates and dries out. New air filter installation is highly recommended to avoid any potential breathing issues that come with a lack of incoming air.

14x25x1 Air Filter Use for Apartments

Air filters in an apartment are integral to air systems to the residence’s small size and the potentially dangerous complications. Apartment air is constantly cycled like a residential home, with new air being just as important to the health. The airflow helps bring in new airflow to enjoy, while the cycling also removes old air and the particles it is carrying. Apartments and homes with resident smokers or pets need consistent airflow to prevent any particles or dander from settling on any open surfaces. A dirty filter prevents fresh air from coming in, but the particles it is unable to let out may be just as damaging to the lungs.

14x25x1 Furnace Filter

The air filters used in the average heating or cooling air system are also installable in the home furnace heating system. The filters are place in between the heated air and the fan that will distribute it throughout your home. Heated air goes through filtration, the home proceeds to enjoy fresh air and warmer temperatures. The furnace filter will become dirty over time, like those installed in other air systems, but the results are potentially dangerous.

Air filters need maintenance or the dirty filters will block airflow and prevent the cycling process. While in a normal air system lack of airflow is bad, furnace systems have the additional problem of contained high temperature heated air. As the air builds up, the temperatures rise to dangerous levels where the system may become severely damage and shut down entirely. Furnace filters need periodic maintenance, like those found in other air systems, to prevent problems and keep the systems problems from becoming too costly.

14x25x1 Air Filter Best Changing Practices

When the air filters in your home need changing, the process is quick and easy but required consistently. The rate of replacement is usually tied to multiple factors, like home environment and filter MERV (Minimum Efficiency Reporting Value) rating. Home’s with resident smokers or pets, or surrounded by high levels of pollutants and allergens, tend to go through filters at a faster rate. A filter’s ability to process the air in certain environments translates into its place on the MERV scale.

Filter King 14x25x1 size premium filters rank as an 8 on the MERV system, providing ample protection for the average home. The rating marks our filters as effective in blocking out particles microns in size, while also open enough to let airflow effectively pass. The MERV rating determines how tight a filter’s mesh weaving is, when it is too tight then airflow may have trouble passing through. Our filters allow for airflow to cycle through your home easily, while also blocking out particles including:

  • Pollen
  • Dust
  • Mold
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Smoke
  • Virus’s

Replacing an Old Filter

The air filter installation process is easy to do, and starts with finding the filter that needs replacing. A filter’s location is found in the system owner’s manual, from there the filter is removed and checked. A dirty filter should be carefully removed to avoid spreading any dust or debris, and its cardboard edge checked for the size. Once the size is known, the correct filter’s will come in for easy installation and cleaner airflow.
