How Often to Change Your 12x30x1 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.

12x30x1 Air Filter

The Filter King premium 12x30x1 air filter provides your home with an important layer of security for any matching HVAC system. The average home is constantly pumping in the air from the outside, but the incoming airflow is not always necessarily clean. Your air systems may bring in all different kinds of airborne particles that are detrimental to your health. Filter King 12x30x1 premium air filters prevent any incoming airflow from bringing in any irritants. The filters will keep the airflow clean, but become dirty themselves, and eventually require replacement.

12x30x1 Air Filter Use for Residential Homes

The air in your residential home is able to flow through in a variety of different ways, but the cleanest is often through the HVAC system and ducts. The reason the incoming air comes in so clean is due to filtration, and your filter's ability to trap unwanted air particles and block out irritants like allergens and pollutants. Your pleated air filter actually consists of a tight mesh weaving designed to trap unwanted air particles and absorb irritants right out of passing airflow. Over time, these filters become so covered in captured particles that the mesh becomes filled and the filter becomes a blockage.

When your 12x30x1 air filters become a blockage in their HVAC system, then that may lead to a series of problems that only become worse over time. Your home needs fresh airflow coming in, or the old air will be unable to cycle out. The old air will begin to stagnate and dry out, which makes it unhealthy to breathe in and generally causes a dip in indoor air quality. New 12x30x1 air filters are clean and able to protect you from harmful irritants while providing you proper air flow and help raise the indoor air quality of your home.

Air Filter Use for Apartments

An apartment generally has fewer options when it comes to ensuring fresh, cleaner air flow and high air quality. Your home’s limited space makes it all the more important that your pleated air filters are working without issue. The air flow in your home flows through more than just one room, it is needed for the entire home. Your HVAC system pushes fresh air into every room it can but that means that certain particles and irritants already in the home travel as well. Apartments with resident smokers or pets may see widespread issues with smoke particles and pet dander if they are not handled by your home air filter.

Eventually, the pleated air filters in your home will require replacement in order to avoid any growing complications with air quality. One of the biggest problems with dirty filter is the effects they have on their respective system. The air system in question will attempt to push air flow pass a blockage by increasing energy usage and pushing the air harder. The rise in electrical usage makes your energy costs go up over time, costing you up to thousands of dollars annually.

12x30x1 Furnace Filter

The 12x30x1 air filters that you purchase for your HVAC system are also able to work for the average home furnace. The filter is able to fit in between the area where incoming airflow becomes heated and the blower fan that distributes it into your ducts. The airflow needs to go through filtration or the ducts in your home may become severely affected by the buildup of irritants and particles like household dust, dust mites debris, mold spores, etc. However, the effects of a dirty filter is often more severe than that of other air systems, requiring consistent maintenance to avoid an incident.

Your furnace system works by heating incoming airflow, filtering the air, and then distributing it throughout your duct system. When the heated airflow from your furnace becomes blocked, then the result is temperature fluctuations throughout the rooms of your home. If the blockage is there for long enough, then the furnace system may not be able to handle the rise in internal temperatures. Over time, the extreme temperatures may cause severe damage to your furnace system and result in some very costly repairs.

Air Filter Changing Practices

Your air filters need consistent maintenance on a regular schedule or the complications will only become worse over time. Your home air systems need clean air filters to push cleaner air flow forward without any issues. When your pleated air filters become a problem, they may cost you up to thousands of dollars and cause severe damage to your air systems. Many of the worst costs are avoidable by simply installing a new air filter. For optimal performance, You should change air filters for your heating and cooling system every 90 days.

Your pleated air filters become dirty at a consistent rate, one that usually depends on a home's environment and the air filters MERV (Minimum Efficiency Reporting Value) rating. Homes in areas with high levels of allergens or pollutants often require more frequent filter changes. The MERV rating determines just how efficient your filters are at stopping airborne irritants. The Filter King premium 12x30x1 size home air filter ranks as an eight on the MERV scale. Our filters are able to block out a full range of particles, while letting cleaner air flow passes through, including:

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

Replacing an Old Filter

When it comes time to replace your air conditioner filters, the process is simple and only requires some of your time. First, you will need to find where the old filters are in order to check their size. You will be able to find the size of the filter on the cardboard edge, and from there order one in a similar size. Once the new filter arrives, throw the old one out but not before sealing it in a bag or container to avoid particles re-releasing. Your new 12x30x1 air conditioner filter should slide into place easily and provide the heating and cooling system with fresh new protection against irritants.
