How Often to Change Your 24x24x1 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.

24x24x1 Air Filter

Your home will need filters in place to keep the air systems clean and working at maximum efficiency. The air that flows through a system is not often naturally clean, it often needs filtration in order to become more breathable and healthy. The 24x24x1 size air filter match many air systems in your home and provide protection for your home against harmful irritants and pathogens. The filters in your home eventually become so full of incoming particles that it begins to affect your home.

24x24x1 Air Filter Use for Residential Homes

The air in your home constantly cycles with new air coming in making sure your home stay clean and fresh smelling. The air your systems pump inside is able to carry a full range of dust, debris pollutants and allergens capable of lowering indoor air quality. Your home with low indoor air quality is often uncomfortable, and possibly dangerous to residents with breathing problems. 24x24x1 air filters help keep the air systems in your home clean, but will eventually require replacement. When dirty air filters are left in a system, then the result is a loss of airflow and severe effects on your home.

Dirty air filters are unable to properly process passing airflow, which means that the air inside your home is not cycled. Over time, old air dries out and begins to stagnate which creates an uncomfortable and unhealthy atmosphere. Your air system will try to push the airflow through the blockage by increasing the energy it uses. The spike in energy ends up raising your home’s billing and wearing down the mechanical parts of a system.

24x24x1 Air Filter Use for Apartments

The air in your apartment has more limited options of dispersal and cycling, in such a small space every breath counts. Your air filters keep incoming airflow fresh and clean, ensuring that your home remains comfortable to live in. Irritants and intruding particles filter out while incoming fresh airflow comes in and raises the air quality. Filtration becomes all the more important when your home has certain particles producing residents that affect your apartment’s air quality.

The airflow in your home cycles, air comes in and then travels through the duct system before exiting. This process allows fresh, clean air to enter while old air flows out along with any airborne particles floating around. For apartments with residents like smokers or pets, it becomes much more important to have the resulting smoke particles or pet dander filtered out. New air filters keep the airflow going and prevent issues with your systems that prevent fresh, clean air from passing through.

20x24x1 Furnace Filter

HVAC 20x24x1 filters work for heating systems and for good reason, the air in a furnace system needs constant filtration. The heated air goes through your filter before distribution, cleaning the incoming airflow as your home warms up. The filter is useful, but will inevitably become dirtier over time which is a serious issue for a furnace. Unlike other systems, a furnace needs its airflow to pass by without issue to avoid severe damage or even dangerous conditions over time.

When the air in a furnace is trapped, then that causes a rise in temperature that the system may be unable to fully handle. The heated air is unable to leave, which causes the rest of your home to have temperature fluctuations room to room. The increase in heat is capable of warping and severely damaging a furnaces parts, which leads to incredibly costly repairs. The system becomes continuously more damaged over time, the situation and accompanying costs are avoidable by simply buying a new 20x24x1 air filter.

24x24x1 Air Filter Changing Practices

Your home will need new filters regularly installed into its many air systems in order to avoid the various issues that crop up over time. The rate of installation usually depends on factors like your home’s environment and the filter’s MERV (Minimum Efficiency Reporting Value) rating. Factors like pollution or allergens tend to cause air filters to become dirty faster, high amounts of the irritants often require more regular filter replacement. The filter’s ability to block out certain irritants ties into its MERV rating.

Your 24x24x1 air filter consists of a tight mesh weave manufactured to capture and absorb passing irritants. The tightness of this weave ranks on the MERV scale, which helps you see just how efficient the filter is. Home filters require more a more balanced MERV ranking, because when the mesh is too tight it restricts incoming airflow. Filter King 24x24x1 air filters rank on the MERV scale as an 8, blocking out basic irritants and particles like:

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

Replacing an Old Filter

When you need to install a new filter, the process only takes a few steps and a short amount of time. First, find the filter’s locations in your air system owner’s manual. Once found, you are able to take out the old air filter and see the required size, in this case 24x24x1, and order a similarly sized filter. Once the new filter comes in, seal the old filter in a container or bag before disposal. Finally, install the new filter and enjoy the fresh incoming airflow.
