For decades, microglass media ruled the HEPA filter market. More recently, HEPA filter manufacturers introduced a number of types of membrane media, providing a more robust, durable alternative to microglass. While the strength of membrane media is widely recognized, not everyone appreciates the features and benefits of membrane media relative to microglass.


AAF Flanders offers HEPA filters made of the traditional microglass, as well as membrane media options in ePTFE, and eFRM. To help you understand which media is ideally suited to your clean environment, we provide a side-by-side-by-side comparison of these media choices.


With this new guide, you will understand how your choice in media impacts:

  • Pressure drop
  • Filter durability
  • Hydrophobic qualities
  • Off-gassing
  • Impact on total cost of ownership (TCO)
  • Testing compatibility
