18x36x1 Air Filter

Filter King 18x36x1 size air filters are important part of your home air systems, used to clean out airflow free of harmful allergens and pollutants. The filters consist of a tight mesh weaving that captures and absorbs particles coming through in passing airflow. The cleaned airflow will then cycle into your home and provide it with a fresh smell while the old air cycles out. Over time, the air becomes cleaned causing the filters to become covered in a layer of captured particles. The dirty air filters are a problem for their system and require replacement before several issues begin to develop.

Your home’s indoor air quality relies on filters and their ability to bring in fresh air that is also cleaned as it is pumped inside. Your air filters are less effective when dirty, airflow is unable to effectively pass through into the duct system. Without fresh air, your home will suffer problems of stagnation and dryness. The air systems will also become strained, leading to costly issues including repairs and raised energy billing.

When you install new air filters, it helps alleviate many of the issues that result from dirty air filters being left in the system too long. We offer replacement 18x36x1 size air filters to replace the old and keep airflow coming in smoothly. Filter King offers a quality delivery service along with a subscription option to have them brought to your home as often as monthly. Our air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight, the MERV rating shows how effective the filter is at blocking out irritants. Filter King air filters are able to block out particles like:

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