How Often to Change Your 20x22x1 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.

20x22x1 Air Filter

The Filter King 20x22x1 size air filter is a premium model protective tool used in air systems to allow clean air in and keep irritants out. Air filter consists of a tight mesh weaving designed to trap and absorb particles such as pollen, household dust, pet dander, mold spores, dust mite debris, bacteria, smoke, smog, and other allergens trying to pass through air flow into your home duct system. Unless stopped, incoming particles can severely impact the comfort and livability of your home. Your air conditioner filters will help keep your home clean, but in the process, they will become dirty themselves. The dirtier your air filter becomes, the more problems they cause, and the more you are going to need a brand new air filter.

Air Filter For Residential Use

The average residential home is constantly pumping in the air, but the incoming airflow’s quality varies from place to place. The air around your home may contain a full range of allergens and pollutants just waiting to float inside. Your home air systems are unable to tell the clean air apart from the dirty, this is where filters come into play. Your air filter will clean up the incoming air flow and raise indoor air quality so that the air inside becomes much safer to breathe in. The air filter is necessary to air systems, but they become a problem themselves after becoming dirty and blocking air flow.

Your air filter needs to be periodically changed for new ones or else the trapped small particles i.e household dust, pet dander, mold spores, etc in their mesh weaving begin to build up. Dirty filter is unable to let air flow pass through easily, which means that old air inside will be unable to cycle out. Old air has the tendency to dry out and stagnate, which is both uncomfortable and unhealthy to breathe in. New 20x22x1 air filters allow air flow to pass through easily and prevent issues that stop your home from smelling fresh and clean.

Air Filter Use for Apartments

The average apartment has fewer options than a residential home when it comes to guaranteeing fresh airflow. Every breath of fresh air becomes important, which makes clean air filters that much more useful to your air systems. Your air filters are not only useful for incoming airflow, but also the airflow traveling between your rooms. Air goes through your ducts and fills the accompanying rooms, as well as taking out certain particles to become filtered. Particles like tobacco smoke and pet dander are among the most common, and important, particles to filter out of air flow as it travels through your duct system.

As the airflow travels through your heating and cooling system, it becomes cleaner as it passes through your filter and the air filter becomes dirtier as a result. Dirty filter is unable to allow airflow to pass, which is worse for air quality when particles already inside a room are unable to ride cycle out of a room. Many different air particles have the tendency to cling to whatever surface they can, covering rooms in layers of grime or dirt. Without regular airflow, your home becomes much less comfortable and more difficult to clean.

20x22x1 Furnace Filter

The 20x22x1 air filters you order for your home may fit the average HVAC system or a heating and cooling system like a furnace as well. For the furnace system, the air filter typically goes in between where the air becomes heated and where the blower fan distributes it into your home duct system. The incoming heated airflow is cleaned of irritants so that they do not cause issues like they would in other air systems. But unlike other air systems, there are much more severe consequences to not replacing dirty furnace filters.

Like other air conditioner systems, the furnace system works with different temperatures that make your home more comfortable. The heated airflow needs to travel through an HVAC system with issues, or the complications that come from having blocked off airflow grow worse over time. Internal temperatures for a furnace may rise to a point where the heating and cooling system will not be able to handle it leading to severe damage and heating problems. These complications are avoidable by making sure that the 20x22x1 air filters in an air conditioner system are regularly replaced.

Air Filter Changing Practices

The air filters in your home air systems need regular maintenance or else the resulting problems start to grow over time. When filters are dirty, they are able to cause all kinds of problems, but all of them generally leads to additional energy costs for your home. Your air systems will attempt to push past the dirty air filters by increasing their energy usage. The resulting spike in your home's electrical use raises energy billing and usually only ends up wearing down the HVAC system's mechanical parts.

The rate at which you should replace your air filters usually depends primarily on your home's environment and your filters MERV (Minimum Efficiency Reporting Value) rating. Typically, You would need to change your air filter every 3 months for optimal performance of your HVAC system. Your home's environment may contain all sorts of irritants that force the filters to constantly need to trap and absorb the passing particles from the air passing through them. The MERV rating of your air filters determines just how efficient they are at actually capturing the particles from the air passing through it over time. Filter King 20x22x1 size filters rank as an eight on the MERV scale and are able to block out irritants like:

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

Replacing an Old Filter

When old filters need replacement, the process is quick and easy with only a few steps required to ensure clean incoming airflow. First, find out what size air filters you are going to need by reading them on the cardboard edge of the old filters. The air filters are locatable using the HVAC system owner's manual to easily find where they are installed. Afterward, you are able to order the correct size air filters and install them smoothly into place to keep incoming airflow clean.
