20x36x1 Air Filter

Filter King 20x36x1 air filters are used by your home HVAC systems to keep cleaner air flow coming in smooth and clean. Your air filters consist of a tight mesh weaving that captures and absorbs passing particles and letting cleaner air flow passes through. The cleaned air cycles throughout your home and helps raise indoor air quality over time. The air surrounding your home may contain all kinds of allergens and irritants that could float inside via airflow. Your air filters will keep the air coming in safe to breathe but become dirtier in the process.

Over time, the air filters in your home will capture and trap unwanted air particles that become a blockage in their heating and cooling system. Dirty air filters are unable to allow air flow to pass through easily, which means that fresh air will not cycle throughout your home. Without fresh air, the air already inside your home will dry out and become stagnant over time. Your heating and cooling system tries to push air flow past the blockage. The effort ends up causing strain that may lead to mechanical damage and a rise in energy billing.

The air filters in your home require consistent replacement in order to avoid several problems with their air conditioner systems. We provide 20x36x1 size air filters ready for purchase and capable of installation as soon as they arrive at your home. We also offer a delivery service, with orders of two or more filters shipped out for free. With our subscription option, you can have new air filters shipped out regularly, as often as monthly if you want. Our filters rate as an eight on the MERV (Minimum Efficiency Reporting Value) scale. This means that they are capable of filtering out particles like:

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

20x36x1 Furnace Filters

The furnace air filters in your home are necessary tools to keep the heated air passing through clean. The filter continues to clean out airflow over time, but like any other filter, they become dirty over time. Dirty furnace filters lead to the same problems of blockage with a lack of fresh airflow for the home. However, the airflow blocked is heated up before filtration and distribution. This means that the heated air builds up, which leads to possible mechanical damage and temperature fluctuations. Order new air filters now and have them delivered to your home on regular basis with an air filter delivery service or subscribe to our home air filter change reminder program.
