Air Filter Efficiency Chart: MERV, EN779 & ISO 16890

MERV, EN779, and ISO 16890 are all standards that are used to measure air filter efficiency.

  • MERV (Minimum Efficiency Reporting Value) is a North American standard that rates filters based on their ability to trap particles of different sizes.
  • EN779 is a European standard that rates filters based on their ability to trap particles of a specific size range.
  • ISO 16890 is a newer global standard that rates filters based on their ability to capture particles across a range of sizes, including very small particles.

Understanding these standards can help you choose the right air filter for your needs.
