FFP2

FFP2 is a class of filtering facepiece respirators defined by the European standard EN 149:2001 + A1:2009. They are designed to protect the wearer from inhaling particulates by filtering at least 94% of airborne particles in standardized tests using a sodium chloride aerosol, placing them between FFP1 and FFP3 in the EN 149 system.

These respirators are commonly used in healthcare, construction, mining, and other settings where dust, aerosols, or biological particles may be present. They are typically disposable and come in various shapes and sizes to fit different faces; many models use headbands for a tighter seal. Some versions include a one-way exhalation valve to reduce breathing resistance and heat buildup, but exhaled air from valve-equipped models is not filtered, which can be a concern for source control in sterile or enclosed environments.

Effectiveness depends on a proper seal to the face. Facial hair, improper donning, or moisture can reduce performance. FFP2 devices are designed for particulates and do not protect against gases or vapors unless used with additional filtration. They should be disposed of after use or according to the manufacturer’s guidelines.

In many markets, FFP2 devices are roughly equivalent to the US N95 and the Chinese KN95 in filtration performance, though certification processes differ and products are not strictly interchangeable. Proper fit testing and adherence to usage instructions are essential for achieving the stated protection level.
