Identify the filtration level of an air filter
We will explain how to identify the filtration level of an air filter and understand the meaning of the symbols related to the ISO 16890 standard.
The ISO 16890 standard, which replaced the old EN 779 standard in 2016, establishes a method for classifying air filters based on their efficiency in capturing different sizes of fine particles present in ambient air. The standard is more representative of real-world conditions, taking into account fine particles PM10, PM2.5, and PM1.
