EN 149:2001- A1:2009 is the European Standard that covers the technical specifications for respiratory protective devices - filtering half masks to protect against particles.
There are 3 classes of masks as defined by the standard:
FFP1 = Lowest class of protection
FFP2 = Higher class of protection
FFP3 = Highest level of protection
This test measures the probability of the respiratory mask to protect the wearer against potential hazards.
A test subject wearing the particle mask walks in an enclosed test room, with a constant concentration of sodium chloride aerosol. While the subject breathes, the air inside the mask is sampled and analysed to determine which % of sodium chloride could pass through the mask.
In the table to the left: The lower the percentage the higher the protection
The goal of this test is to measure the filtering power of the masks.
This test is carried out by exposing a dummy head with a mask to 120mg of 2 test aerosols (Sodium chloride & Paraffin oil). The standard defines the maximum admitted penetration % of the 2 aerosols, for FFP1/FFP2 and FFP3 masks.
In the table to the left: The higher the penetration levels the lower the protection
This test assesses the ability of the filtering mask to provide protection while allowing the wearer to breathe easily.
In the table to the left: The permitted resistance is lower for FFP1 because it's a lighter mask and it's higher for FFP2 and FFP3 as they are thicker.
Experience ultimate comfort and protection with our FFP3 valved respirator. With low breathing resistance, an innovative moulded nose bridge, and an all-round foam gasket, it's ergonomically designed to fit most face shapes. The wide adjustable elastic head straps provide a secure and comfortable fit, while the high-performing exhalation valve efficiently reduces heat and moisture inside the mask. R D certified reusable for more than one working shift, and with a Dolomite clogging test for maximised breathing comfort, it's the perfect choice for your respiratory needs.
