How Often to Change Your 25x29x1 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.

25x29x1 Air Filter

Filter King 25x29x1 size air filters are tools used by the various air systems in your home to keep airflow pumped in clean. The filters consist of a tight mesh weaving that allows airflow to travel through but blocks out harmful irritants. Clean air is then able to enter the home and cycle throughout, raising air quality in the process. This process is necessary to keeping incoming airflow clean, however it also dirties the air filters in the system over time. When the air filters in a system become dirty, they cause problems for their system and eventually for your home as a whole.

Filters become dirtier over time as their mesh weaving becomes more and more covered in particles. When the filters become completely covered, they are unable to allow airflow to travel through without any issues. Without fresh air, your home will go through issues of dryness and stagnation over time. Your air systems will try to push airflow through the dirty filters but that may lead to increased strain. If the systems is strained for long enough, then your system may suffer from expensive mechanical damage over time. Strained air systems also use up additional electricity which leads to a rise in energy billing for your home over time.

Filter King has brand-new 25x29x1 size air filters available that are capable of installation upon delivery. Orders of two or more filters are delivered for free and regularly if you use our subscription option. All air filters are rated on the MERV scale to gauge their ability to clean out incoming airflow. Our filters rate as an eight on the MERV scale and clean airflow free of particles like:

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

25x29x1 Furnace Air Filters

The furnace filters in your air systems are used to keep incoming airflow clear of irritants capable of polluting your air systems. The furnace filters in a system will eventually become dirty and cause problems due to the heated airflow they block. Without release, the heated airflow builds up and that may lead to temperatures reaching the point where the system becomes damaged. Your home will also see temperature fluctuations as the air is unable to warm its rooms. Avoid these issues by ordering new air filters today and keeping the airflow coming in clean.
