How Often to Change Your 12x12x1 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.

12x12x1 Air Filter

The average air systems require air filters in order to make sure that the incoming airflow stays clean. The airflow pumped in from outside is able to carry all sort of irritants that are able to make your home uncomfortable, with hard to breathe air. Our 12x12x1 match the average air system and protect the home against floating particles and irritants. Your air filters will clean out incoming airflow by trapping or absorbing the passing irritants before they have a chance to enter the ducts. The filters in your home will eventually become dirty, with so many particles trapped and absorbed that airflow has difficulty coming through.

12x12x1 Air Filter Use for Residential Homes

The fresh air in your home does not stay clean and healthy forever, over time the air begins to stagnate and dry out. Fresh air is necessary for your home to maintain its indoor air quality and prevent any developing issues with resident breathing. When your home suffers from low indoor air quality the effects are often an uncomfortable atmosphere and possible problems with allergy triggers. Your air filters keep irritants out of your home and raise air quality, but in the process become dirty themselves. Air filters need maintenance, or else the dirty filters will begin to cause problems for your home.

Dirty air filters are a blockage in your air systems, preventing airflow from efficiently passing by into the ducts. While dirty air filters still block out issues like dust, debris, pollutants and allergens, the lack of fresh air is a problem. Old air quickly stagnates and dries out, leaving behind air quality that is unhealthy to breathe in over any length of time. The air system will attempt to bypass the blockage by increasing energy usage, but the result usually only ends up being an increase in your home’s billing.

12x12x1 Air Filter Use for Apartments

Your apartment needs clean air filters in order to ensure that the limited space available has high enough air quality to remain comfortable. The incoming airflow needs filtration to ensure that both incoming and outgoing airflow stay clean throughout your home. The airflow traveling through the ducts is able to become contaminated with particles originating from inside and outside your home. Apartment residents like smokers or pets are able to create irritants that fill the air and lower air quality if not carried out on airflow and filtered.

When your apartment’s air filter are dirty then the results are the expected lack of fresh air leading to stagnation. The costs of a dirty filter begin to rise rapidly when the problem is not fixed soon. The air system uses more energy which places more pressure on its components as they work longer and harder over time. Eventually, the parts wear down and require replacing as well which is much more costly than simply buying new filters for the system.

12x12x1 Furnace Filter

The Filter King 12x12x1 air filters are able to match a variety of air systems, including those for your furnace. Your furnace filters go in between where the air heats up to the appropriate degree and the blower fan that distributes it. The airflow travels through the filters tight mesh weaving where irritants become trapped or absorbed, leaving the fresh air to pass through. The filters will eventually become dirty, which is a large issue for furnaces then it is for other air systems in the home. The airflow that a dirty filter blocked becomes heated even further, meaning that the system is in danger from a serious case of overheating.

When heated air cannot leave the furnace the result is a rise in temperature the system may not be able to handle properly. The rest of your home feels the effects of the trapped air as well, various rooms will suffer from temperature fluctuations due to the inconsistent heating. The increase in temperature also creates an increased strain on an air system’s internal machinery. The metal of various parts may warp or become severely damaged over time, causing costly repairs that may have otherwise avoidable with a new filter.

12x12x1 Air Filter Changing Practices

New filters are often required on a regular basis, the rate of change depending on your home’s environment and MERV (Minimum Efficiency Reporting Value) rating. The environment of your home refers to both external and internal factors that may dirty your air filter at an increased rate. Homes surrounded by high levels of pollutants and allergens, or with resident smokers or pets, tend to need more regular filter maintenance. The environment only really affects your air filter when it has a high ability to properly clean out passing airflow.

Your 12x12x1 air filter is able to trap and absorb passing irritants, its ability to do so is measured and ranked on the MERV scale. The tighter a filters mesh weaving, the higher its rank, and the more efficient it is at blocking out particles. The best filters for your home usually rank around the middle of the MERV scale, preventing the tightness of the mesh weave from causing airflow issues. Filter King premium 12x12x1 air filters rank as an 8 on the MERV scale, and are able to block out irritants microns in scale like:

  • Pollen
