Why Buy Air Filters From Filter King?

Image

In comparison to fiberglass filters, 12x25x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Image

Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.

Image

Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 12x25x1 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.

12x25x1 Air Filter

Filter King 12x25x1 size air filters act a way to help ensure fresh incoming airflow for your household. Your home may have high levels of pollutants and allergens in the surrounding air, which makes it that much more important to keep your home’s airflow clean. Without filtration, the ducts and rooms throughout your home may be subject to particles that affect indoor air quality. The air filters are installed for the express purpose of cleaning up incoming airflow, but become dirty in the process. Dirty air filters are a problem, and they need replacement as soon as possible to avoid any rapidly growing issues throughout your home.

Your air filters keep incoming airflow clean by drawing passing particles into their tight mesh weaving. The mesh weaving eventually becomes so full of particles that it becomes a problematic blockage for an air system. Your home needs consistent incoming airflow or the effects become more evident inside your home over time. Old air becomes dry and stagnate, which is both unhealthy and uncomfortable to breathe in.

Dirty air filters also cause an increase in your home’s energy billing, as well as strain the mechanical parts of an air system. When you install new air filters, the airflow is allowed to travel through your air systems much more naturally. Our air filters also clean the airflow well, with the mesh weaving having a MERV (Minimum Efficiency Reporting Value) rating of eight. Your new 12x25x1 air filters are capable of blocking out particles like:

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