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.
