EN18221

EN18221 is a European standard that specifies requirements for the performance and construction of respiratory protective devices. Specifically, it covers the testing of filters for air-purifying respirators. The standard is divided into several parts, each addressing different types of filters and their performance characteristics. These parts detail the methodology for testing the efficiency of filters against particulates, such as dust, mist, and fumes.

The standard is crucial for ensuring the safety and effectiveness of respiratory protective equipment used in various environments, including industrial settings, healthcare, and general public use. It helps manufacturers to design and produce filters that meet stringent performance criteria, providing adequate protection to users from airborne contaminants. Compliance with EN18221 is often a prerequisite for placing these devices on the market within European Union member states and other countries that recognize the standard.

The testing procedures outlined in EN18221 involve exposing filters to specific challenge aerosols and measuring the penetration of these particles. Different classes of filters are defined based on their efficiency levels, allowing users to select the appropriate level of protection for their specific needs and the types of hazards present. The standard is regularly reviewed and updated to incorporate advancements in technology and evolving safety requirements.
