A panel filter, also known as a flat panel filter, is a type of air filter that is composed of a pleated or folded filter media that is held together by a frame. The filter media is typically made of a synthetic material such as polyester or fiberglass. Panel filters are typically used in residential and commercial HVAC systems to remove airborne particles from the air. They are relatively inexpensive and easy to install, making them a popular choice for a wide range of applications.
Panel filters are available in a variety of sizes and efficiencies. The efficiency of a panel filter is determined by its MERV rating, which stands for Minimum Efficiency Reporting Value. The higher the MERV rating, the more efficient the filter is at removing airborne particles. Panel filters with a MERV rating of 8 or higher are considered to be high-efficiency filters and are effective at removing allergens, dust, and other harmful particles from the air.
