EN 149 is a European standard of testing and marking requirements for filtering half masks. Such masks cover the nose, mouth and chin and may have inhalation and/or exhalation valves.EN 149 defines three classes of such particle half masks, called FFP1, FFP2 and FFP3, (FFP = filtering facepiece) according to their filtering efficiency. It also classifies masks into "single shift use only" (not re-usable, marked NR) or "re-usable (more than one shift)" (marked R), and an additional marking letter D indicates that a mask has passed an optional clogging test using dolomite dust. Such mechanical filter respirators protect against the inhalation of particulates such as dust particles, droplets, and aerosols.
Approvals and Standards
FFP2 & FFP3 particular filtering mask certificated in accordance with the European standard EN 149:2001+A1:2009. Respiratory Protective Devices. Filtering Half Masks to Protect Against Particles. Personal Protective Equipment Regulation (EU) 2016/425 Annex 5 it is approved.
FFP2 FILTERING HALF MASK
This mask offers protection in various areas such as the glass industry, foundry, construction, pharmaceutical industry and agriculture. It effectively stops powdered chemicals. This mask can also serve as protection against respiratory viruses such as avian influenza or severe acute respiratory syndrome associated with the coronavirus (SARS), as well as against the bacteria of pneumonic plague and tuberculosis.
It is similar to the N95 mask.
FFP3 FILTERING HALF MASK
EN 149 tests the ability of masks to protect the wearers against inhaling liquid and dry aerosols. It makes no statement about, and does not specifically test the suitability of such masks for, infection control against airborne transmission of pathogens through respiratory droplets. Nevertheless, FFP2 and FFP3 masks are commonly used for this purpose in medical practice.
Type IIR (Type 2R) face masks are a high-end solution designed primarily for protecting others from the wearer transmitting infection to the patient or surrounding environment. They include fluid resistance, to counter protect the wearer from being splattered with human bodily fluids, particulate matter and micro-organisms. Ideal for moderate to light amounts of fluid, spray and/or aerosols.
Specification for Type IIR face masks is as follows:
