How Often to Change Your 10x30x0.5n 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.

12x20x1 Air Filter

The air system’s in your home require an air filter to ensure that the airflow your home needs stays fresh and clean. The Filter King 12x20x1 air filter is able to fit many different air systems in a variety of homes. Any irritants in the air flow passing through the filter become trapped and absorbed in its intricate mesh weaving before it has the chance to enter your home ducts. The irritants that are able to enter a home through air flow are able to cause a variety of issues throughout a home. The pleated air filters in an HVAC system will prevent any complications with irritants but in the process become dirty and cause issues themselves.

12x20x1 Filter Use for Residential Homes

The air in residential homes cycles in a variety of ways from HVAC air conditioner systems to having the windows open. The HVAC system with filtration makes sure that the air passing through becomes cleansed of irritants. Cleaner air flow prevents breathing issues that would otherwise make a home uncomfortable or unsafe. The more filtered and cleaned up a home’s air, the higher its indoor air quality will be, and the more comfortable it is. The filtration process is good for the home, but the dirty filter will eventually require replacement to avoid certain problems with incoming airflow.

The dirty air filters in your home heating and cooling system become blockages that make it difficult for passing air flow to reach your ducts. The dirty filters are still able to stop all manner of household dust, debris, pollutants, and allergens, but at the cost of blocking out additional air flow as well. Air needs to cycle out in a home because otherwise it stagnates and becomes a problem. Dried out, stagnant air is unhealthy to breathe in and is only one of the many problems that come with dirty air filters.

12x20x1 Filter Use for Apartments

Your apartment has fewer options when it comes to cycling the air inside, and less space in general meaning every breath counts. Your home air filter will cleanse out incoming and outgoing air flow to make sure that every room stays fresh and clean. The filtering is especially necessary for homes with resident pets or smokers, the unwanted air particles that result tend to stick to open surfaces when not filtered out. Dirty air filters cause problems to develop before air flow becomes blocked completely.

Dirty air filters end up costing you more than just the price of a new filter, over time they begin to rack up billings in other ways. When a heating and cooling system cannot fully process proper air flow, the HVAC system will attempt to push it through by increasing its energy costs. The increased mechanical strain increases energy billing and heavily strains the pieces of a HVAC system, wearing them down faster. The parts eventually break down, leaving an apartment with problems that could have otherwise been avoided with a new filter.

12x20x1 Furnace Filter

A Filter King 12x20x1 size filter is able to fit into HVAC air conditioner systems, it is also able to fit into certain furnace heating systems as well. Your furnace filter cleans out the incoming airflow after the furnace heats it up, but before it distributed via blower fan. The airflow is cleansed, the unwanted air particles trapped or absorbed, and the heated air is able to warm home without issue. However, like the other air systems, a furnace will need to replace its furnace filters over time in order to avoid any issues with airflow blockage. In the case of a furnace filter, maintenance is required due to the increased risks involved.

With a furnace, air flow needs to flow out or the lack of air flow causes internal temperatures to rise to an extreme degree. The home feels the effects of the lack of heated airflow, with temperatures fluctuating from room to room. The heated air becomes trapped in a furnace and the resulting rise in temperature may warp different parts and increase energy usage. The costs for repair and billing are avoidable by installing a new filter, which is only a fraction of the price of repairs.

Air Filter Changing Practices

You often need to replace your old filter when they become too dirty due to all the irritants it has blocked over time. Your filter's ability to block irritants is based on its MERV (Minimum Efficiency Reporting Value). Your filters mesh weaving ranks on the scale and from there you are able to see just how effective it is at blocking out irritants. The Filter King 12x12x1 size pleated air filters ranks 8, 11 or 13 on the MERV scale, and are capable of blocking out irritants like:

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

The filters efficiency also ties its ability to block out irritants in certain environments where filters are much more important. Homes in highly polluted areas, or with residents like smokers or pets, need pleated air filters in order to ensure cleaner air flow for residents.

Replacing an Old Filter

Installing a new filter is quick and easy, only requiring you to follow a few easy steps that only need a little time. You are able to use the owner’s manual for an HVAC system to find where the new filters are going to need installation. From that location, you will be able to remove the old filters and note their size along the cardboard edge, in this case, the size is 12x20x1. The old dirty filter should be sealed in a container or bag, while the new filter becomes installed in its place.
