How Often to Change Your 12x36x1 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.

12x36x1 Air Filter

Filter King 12x36x1 size air filters are active tools that consistently clean out incoming airflow of harmful irritants. The filtration provided helps ensure that the indoor air quality of your home does not suffer over time. Your pleated air filters consist of tight mesh weaving designed to capture and absorb airborne particles like mold spores, household dust, airborne allergens, etc traveling in passing airflow. The pleated air filters are easily installed in an accompanying air conditioner system to provide a layer of protection, but they become dirtier the longer they go without a replacement.

Over time, your pleated air filters will capture and absorb dirt constantly until they are covered in the trapped particles. Dirty air filters are unable to properly allow the passage of airflow into your home. The resulting lack of airflow will stop air from cycling through your home, resulting in dryness and stagnation. Dirty air filters also cause their connected HVAC systems to use more energy in an attempt to push past the blockages, resulting in increased energy costs and HVAC system strain.

When you neglect to replace your pleated air filters, then the resulting problems may cost you thousands of dollars annually. New pleated air filters will allow airflow to pass through naturally while also keeping it clean. We offer a range of regular size filters and we also offer custom size filters. Our 12x36x1 size pleated air filters have MERV ratings (Minimum Efficiency Reporting Value) of eight, eleven, or thirteen. Our pleated air filters are capable of blocking out irritants like:
