The main components of a HEPA filter include various elements that work together to ensure efficient filtration of airborne particles. The correct answer highlights these essential components:

  • Media: This is the core part of the filter where the actual filtration occurs. The media is designed to trap particles that are larger than a specific size, typically 0.3 microns, which is critical for HEPA filters to meet their performance standards.
  • Separators: These are integral to maintaining the integrity of the filter media. They provide structural support, ensuring the media maintains its shape and spacing, thus optimizing airflow and maximizing filtration efficiency.

  • Filter Pack: This component is the assembly of the media and separators, arranged to create the necessary surface area for capturing pollutants while allowing air to flow through the filter.

  • Sealant: This is used to bond the edges of the media to the frame securely, preventing air from bypassing the filter and ensuring that all air must pass through the HEPA media.

  • Framing: The frame provides structural support and helps maintain the filter's shape throughout its operational life. It is crucial for ensuring that the filter can be installed correctly in various HVAC systems.
