The EN 149 standard applies to particle filtering half masks, commonly referred to as disposable dust masks. It sets out the essential requirements for materials, field of vision, performance, markings, and the information that must be provided to the user.
To ensure their effectiveness, these respirators undergo both laboratory tests and work simulation tests involving real users. These tests assess factors such as breathing resistance, filter penetration, clogging, carbon dioxide content of inhaled air, and the mechanical strength of valves and connections.
Under EN 149, disposable masks are classified into three protection levels:
- FFP1 – Provides a low level of filtration with at least 80% filtering efficiency.
- FFP2 – Offers a medium level of protection with 94% filtering efficiency.
- FFP3 – Delivers the highest level of protection with 99% filtering efficiency.
These levels help users choose the appropriate mask depending on the type and concentration of hazardous particles in their working environment.
Key points:
- EN 149 covers particle filtering half masks (disposable dust masks).
- Masks must pass strict testing for breathing resistance, penetration, clogging, CO₂ levels, and structural integrity.
- There are three protection levels: FFP1 (80%), FFP2 (94%), and FFP3 (99%).
- The higher the FFP rating, the greater the protection.
- These standards help ensure both safety and comfort during use.
