How Often to Change Your 20x34x1 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.

20x34x1 Air Filter

Filter King 20x34x1 size air filters are utilized in your home air systems to keep airflow coming in, but also keeping it clean. The cleaning process in continuous since your air systems are constantly bringing in fresh air to cycle through your home. Clean air raises indoor air quality as the old air cycles out and irritants are prevented from polluting your home. The air surrounding your home may contain any number of allergens or pollutants just waiting to float inside. Air filters are the tools used to keep the airflow clean, but they become dirty in the process.

Dirty air filters are the result of the filter’s tight mesh weaving capturing and absorbing an overabundance of air particles. The resulting blockage is an issue for the system they become installed and the rest of your home as well. Airflow is unable to pass through dirty air filters easily, which leads to dryness and stagnation throughout your home. Your air systems will try to push airflow past the blockage that will lead to mechanical damage and an increase in energy billing over time.

Your air filters require frequent replacement, or several problems will crop up throughout your home. Filter King 20x34x1 size air filters are available for purchase and ready for use upon delivery.

20x34x1 Furnace Filters

Your home needs furnace air filters in order to make sure that the heated airflow comes in clean and safe.
