How Often to Change Your 12x24x1 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.

12x24x1 Air Filter

The different sized air filters in your home are essential parts of the system and clean up incoming airflow. The air pumped in by an air system is not always healthy to breathe because of household dust and other irritants, the air surrounding your home is often full of harmful irritants. Filter King 12x24x1 size air filters match the average air system and used to keep incoming airflow from creating any problems with the corresponding HVAC system. The air filters themselves consist of a tight mesh weaving that traps and absorbs passing irritants in the airflow. The filter will continue to clean incoming air flow until the point where it is completely covered in captured particles. A dirty filter becomes a problem in an heating and cooling system, meaning that maintenance becomes necessary before the problems begin to spread.

Air Filter Use for Residential Homes

The average home has its fair share of irritants traveling through the air conditioner systems. Your filters prevent any problems by blocking out household dust, debris, pollutants and allergens alike. Many of the irritants that ride along airflow are harmful to the lungs, the irritants are also able to trigger allergies or other severe reactions. The air filters prevent airborne irritants from spreading but can only do so until they become too dirty to properly work anymore. Dirty air filters still block airborne problems, along with the rest of the air that your home is going to need.

A dirty air filter makes it very difficult for airflow to pass by into the ducts of your home. While irritants cannot pass, the lack of fresh air will become more and more noticeable over time. Your home needs its air cycled before it begins to dry out and stagnate, because old air leads to lower indoor air quality. Fresh air filters let airflow through without an issue and prevent the air quality from lowering, from either stagnation or from intruding irritants.

Air Filter Use for Apartments

When it comes to your apartment it becomes more important than ever to ensure clean airflow because of the limited space. Your apartment air filters will clean out incoming air and prevent the particles already inside from causing further problems. Irritants like smoke particles and pet dander have the tendency to stick to whatever surface they land on whenever they are not cycled out of a room’s air. Your home is much more comfortable when the harmful particles cycle out in airflow, before being trapped and absorbed. The capturing process does not happen as effectively with old, ineffective air filters. New 12x24x1 air filters are clean enough to allow air to cycle while also keeping irritants from passing along to other rooms and continue causing problems.

12x24x1 Furnace Filter

Air filters that work for HVAC systems also fit in furnace systems, cleaning the heated air flow passing by to reach your home ducts. Furnace filters are in between where the air heats up and where the blower fan used to distribute it throughout your home. The air filters become dirtier over time and because the air heats up before filtration this becomes a serious problem. A dirty air filter is a blockage in a system which damaging and dangerous to a furnace when heated air is unable to pass.

When your furnace filters become dirty, then the blockage they create stops air flow from passing through. In other heating and cooling system, a blockage leads to stagnant air and lower indoor air quality, for a furnace the effects are much worse. When air flow is unable to leave the furnace, then the result is an increase in temperatures that the machinery may be unable handle. The furnaces parts may become damaged beyond repair, new parts are costly and unnecessary when a new filter solves the problem at a fraction of the price.

Air Filter Changing Practices

You will need new filters over time to prevent any blockages or issues from developing in an HVAC system. How often your air filters will need replacing is often dependent on your home’s environment and the filters MERV (Minimum Efficiency Reporting Value) rating. Home’s with resident smokers or pets often need air filters to prevent the resulting particles from spreading throughout their rooms. Areas with high levels of pollution or vegetation often require homes with more efficient filters to prevent the spread of harmful irritants, allergens, household dust and mold.

Air filter efficiency ranks on the MERV rating system, its number being the result of various measurements. The tight mesh weaving of your filter ranks on the scale and that ranking shows what particles it is able to capture. Filter King  filters rank as an eight on the MERV scale, which means basic irritants are unable to pass along with other particles including:

  • Pollen
  • Household dust
  • Mold
  • Household dust Mites debris
  • Bacteria
  • Pet Dander
  • Smoke
  • Viruses

Replacing an Old Filter

When you need to install a new filter, then the process only takes a few steps and some time. The location of the air filter is in the air conditioner system owner’s manual, once found and removed you can find the size along the cardboard edge. The new air filter should come in a similar size and from there it is easily installed into the system. The old filter goes into a sealed bag or container to prevent the particles from re-releasing, and you enjoy the resulting fresh, clean air.
