What characterizes an FFP2 face mask, and how do I recognize these?
FFP face masks primarily protect the wearer against harmful particles, tiny droplets, and aerosols. FFP is a short form of filtering facepiece. In German, the face masks are well-known as ‘partikelfiltrierende Halbmasken’ means; particulate filtering half masks. The FFP2 face mask, originally intended as a professional protective face mask, is also famous as a ‘dust mask’ in the production industry. It is commonly white, often cup-shaped, foldable, and comes with or without a breath valve. The primary factor in which the FFP Belt face mask differs from each other and affects the designation is the respective filtering capability.
Does a face mask protect against aerosols?
All FFP face masks have to be tested and filter out varying amounts of the test vaporizers. FFP1 face masks must filter out a minimum of 80%, FFP2 face masks around 94%, and FFP3 face masks up to 99% of test aerosols. Testing is completed in line with the European standard with aerosols and guarantees that the FFP face masks available on the market achieve technical norms and have verified to protect against aerosols. The CE label shows that an FFP face mask has successfully undergone a conformism assessment procedure and is therefore printed on the face mask’s surface.
A face mask’s filtering capacity can provide its best protection if the face mask seals tightly to the face along all the edges.
The face mask reminds you not to touch the face.
Another potential route of transmission of the coronavirus is slander infection. For instance, the virus can land on door handles and, from there, spread to the hand of an uninfected person. If this person then involuntarily touches his or her mouth or nose with the hand, the virus can be absorbed by the mucous membranes. In this situation, a face mask can reduce the probability of infection – just by reminding its wearer not to touch the face, nose, eyes, and mouth with their hand.
Does an exhalation valve deliver better protection against the COVID-19?
In contrast to community face masks, the FFP2 manufacturer’s design belt face mask to protect others and yourself. However, face masks with exhalation valves offer a considerably lower level of protection to others than face masks without exhalation valves. The aerosols exhaled by the exhalation valve are not captured by the material but are only to a substantial degree slowed and whirled around by the valve. Though you can ensure self-protection against infection, the people around the wearer of a face mask with an exhalation valve are exposed to his or her aerosols and hence not endangered.
Can you reuse FFP2 face masks?
In the professional area of industrial health and safety, FFP face masks are for single use only. Trained personnel (like in medical care or construction) is often open to an increased risk of transmission. However, in daily lives, people are generally available to lower pathogen loads. It is why several people decide not to throw their privately used FFP2 face masks away after one use as intended but to wear them several times.
