What is Inward Leakage of a FFP2 or FFP3 Filtering Half Mask ?
When using a FFP2 or FFP3 filtering half mask, Air enters the particle filtering half mask and passes directly to the nose and mouth area of the facepiece or, via an inhalation valve(s) if fitted. The exhaled air flows through the filter material and/or an exhalation valve (if fitted) directly to the ambient atmosphere. These devices are designed to protect against both solid and liquid aerosols.
Total inward leakage
The laboratory tests shall indicate that the particle filtering half mask can be used by the wearer to protect with high probability against the potential hazard to be expected.
The total inward leakage consists of three components: face seal leakage, exhalation valve leakage (if exhalation valve fitted) and filter penetration.
For particle filtering half masks fitted in accordance with the manufacturer’s information, at least 46 out of the 50 individual exercise results (i.e. 10 subjects x 5 exercises) for total inward leakage shall be not greater than
25 % for FFP1
11 % for FFP2
5 % for FFP3
and, in addition, at least 8 out of the 10 individual wearer arithmetic means for the total inward leakage shall be not greater than
22 % for FFP1
8 % for FFP2
2 % for FFP3.
Buda-U FFP2 and FFP3: Good Performance in its Inward Leakage.
It is worth mentioning that FFP2 and FFP3 actually are very high level of EU protective mask. The protective effect is impressive and its application range is also very wide. In the EU PPE standard, the test standards for other items are extremely harsh, especially the leakage rate. As we all know, the leakage rate of mask is closely related to the protective performance of a mask.
Obviously, The fact is, although the face mask has high flitration efficiency, the Face Mask is still worthless if its leakage rate is too high.
With consideration of wearing comfort by users, in the meantime, Buda-U engineering team has also tried tremendous efforts in order to lower down the leakage rate. The leakage test of Buda-U FFP2 and FFP3 proved to be excellent. Our mask Shape design can mostly fit different face shapes and contour pressure point on face, and more importantly, Buda-U FFP2 and FFP3 face Masks have perfectly passed the rigid test by the Lab.
