How Often to Change Your 24x25x1 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.
24x25x1 Air Filter
Filter King 24x25x1 size air filters are valuable tools that your air systems use to continue bringing in fresh airflow. The air coming into your home could also be carrying any number of airborne irritants. Your air filters prevent entry to harmful particles by capturing them in a tight mesh weaving over time. This mesh weaving will eventually become completely covered in captured particles and grow less effective over time.
Dirty air filters are a problem for your home due to the fact that income airflow is usually blocked by them. Without fresh airflow, then the air throughout your home will begin to dry out and stagnant over time. Your air systems try to push airflow past the blockage, but usually only end up straining themselves in the process. If the new air filters are not installed then the old ones will cause mechanical damage as they system continues to try and push airflow past it. You will also see a rise in energy billing as electricity use is increased over time by the strained systems.
