FFP3 NR with Valve particle filltering half mask for CE approval
FFP filters are considered functionally equivalent to certain other filter standards regulated under other jurisdictions, such as N95 mask of the United States and KN95 filters of China. However, slightly different criteria are used to certify their performance, such as the filter efficiency, test agent and flow rate, and permissible pressure drop.
The EN 149 standard defines performance requirements for three classes of particle-filtering half masks: FFP1, FFP2 and FFP3. The protection provided by an FFP2 (or FFP3) mask includes the protection provided by a mask of the lower-numbered classes.
Class | Filter penetration limit (at 95 L/min air flow) | Inward leakage | Typical Elastic Band |
---|---|---|---|
FFP1 | Filters at least 80% of airborne particles | <22% | Yellow |
FFP2 | Filters at least 94% of airborne particles | <8% | Blue or White |
FFP3 | Filters at least 99% of airborne particles | <2% | Red |
