How effective are face masks against the coronavirus (COVID-19)?
FFP2 face masks provide excellent protection against airborne coronavirus particles. FFP2 face masks protect the user and those in the vicinity. By wearing an FFP2 mask one contributes to reducing the spread of the virus. Almost all masks assist to some degree but not to the extent of an FFP2 or FFP3 mask.
For adequate effectiveness of the face masks it is important to wash your hands prior and after use of a mask.
Differences between FFP face masks explained
FFP masks are available in different classes. Masks which are primarily used in renovation and building activities (FFP-1 standard) and masks which effectively protect against viruses (FFP-2 norm). Our FFP2 face masks are CE certified and comply with all applicable EU norms and thus protect against the corona virus.
Surgical face masks are used a lot during the pandemic. Unfortunately, these hardly protect against the fine aerosolized particles which can contain the corona virus. Contrary to FFP2 masks, surgical masks are not tested 'as-worn' (which means that the fit between mask and skin is not a test criteria). Surgical masks are only tested for cloth caracteristics. And the cloth is allowed to let particles pass through which are 10 times the size allowed for an FFP2 mask.
What is FFP2?
In Europe approved face masks need to comply with the European standard EU 2016/425 / EN 149:2001. This standard for respiratory protection is divided in 3 classes (FFP1, FFP2 and FFP3). All classes need to filter ultra fine particles of 0,3 micron. The difference is the percentage of particles which will be filtered out.
FFP1 is the lowest class and filters only 80% of aerosolized particles. This standard permits a leakage of up to 22%. These types of masks are primarily used in construction activities and not in the health sector..
FFP2 masks filter an impressive 94% of the particles in the air. In addition, these masks allow a leakage of only 8% around the borders. Because of the effectiveness and the ease of fitting these FFP2 masks are mostly used by health care professionals. During the pandemic they are used a lot for protection against the corona virus.
FFP3 is the standard for masks with an aerosol filtration of 99% and a maximum leakage of 2%. These masks are better than an FFP2, but also have disadvantages. They are much more expensive, a perfect fit is even more important and not always easy, and breathing requires more effort. Hence, FFP3 is used in the most exacting cirmumstances (like asbest removal activities or in labs which deal with dangerous substances or bacteria).
How to recognize an approved FFP2 face mask?
- A Notified Body is supervised under stringent EU rules to ensure that the testing is done precisely according to the norms and regulations.
- Each Notified body has a unique registration number issued by the EU.
- After testing a selection of the products, an evaluation of the design criteria and an audit of the production process a CE certificate of approval can be issued. Subsequently, the import and sale of the approved products can start in the EU.
- Now you are on the official EU website with a listing of all approved and registered Notified Bodies
- Our masks have been tested by Notified Body with registratienummer 2163 (= Notified Body registration # for Universal NB)
- Search for '2163'. Then click on the link to the website of this Notified Body. That way one can be sure to access the correct site for that organization.
- On this website the validity of the CE certificate for our masks can be checked.
- The certificate number for our FFP2 masks is 2163-PPE-1160
Quality of Duuja's FFP2 face masks
|FFP2 norm - minimum||Duuja FFP2 masks|
|Sodium Chloride testing||94%||99%|
|Paraffin Oil Testing||94%||98%|
What is the difference between KN95 en FFP2?
KN95 is a Chinese standard which indicates the quality of face masks.
The KN95 norm is equivalent to the FFP2 norm described above. The minimal required filtration percentage for KN95 is slightly better than the European FFP2 class.
- >90% (KN90) >80% (FFP1)
- >95% (KN95) >94% (FFP2)
- >99,97% (KN100)>99% (FFP3)
HOWEVER: KN95 is not an allowed standard in Europe. During the panic of the first corona wave a temporrary exemption was introduced. Until June 2020, KN95 masks without CE certificate could be imported from producers which were regulated by the Chinese government. With the understanding that such KN95 masks could only be used in the medical sector and were not destined for sale to the general public..
Unfortunately, during the panic of the first corona wave a lot of sub-standard product with a KN95 stamp was brought into Europe. Products which did not comply with the Chinese standards, but which were nevertheless imported by shady companies. Sometimes in good faith. Often deliberately. Long lists circulate of companies and brands which have commercialed inferior masks.
As of June 2020 all FFP2 maskers need to comply with the EU CE certificate rules, and are then sold as an FFP2 mask with CE seal and certificate. Buying a mask with a KN95 stamp is a big gamble. It could be a legitimate, well functioning mask. But possibly it is a non-effective counterfeit product. Why take the risk when approved FFP2 masks are available?
What is the minimum FFP for health care professionals?
In Europe, the minumum requirement for face masks for health care professionals is FFP2 or FFP3. These masks provide the required filtration needed for the treatment of patients who (possibly) are infected with the corona virus.
When should an infected patient wear an FFP2 mask?
As soon as a patient is suspected to be infected with the corona virus, the patient should immediately wear a mask of at least the FFP2 class or higher. This will protect their health care professionals against contact with the virus.
Should an essential worker wear an FFP2 mask?
Does your profession not allow working at a safe (minimum 1.5 meter) distance from your customer or colleagues? Or do you work in a closed environment together with others, with possibly insufficient air circulation? The only way to ensure you protect yourself and others is through the use of an FFP2 mask. Thus you indicate to customers and collegues that you take the risk and their health seriously
How effective are FFP2 masks?
A (corona) virus, can spread by adhering to droplets which leave our lungs via coughing, sneezing, breathing or talking. Such droplets can travel 1,5 meter and infect anyone who gets in contact with such droplets. In addition, the droplets can adhere to surfaces which are later touched by someone who then touches mouth, nose or eyes and thus gets infected.
In the meantime various studies have confimed that the virus is aerosolized. This means that it sticks to miniscule droplets which can remain suspended in the air for a long time in insufficiently ventilated indoor areas. It explains why there was this massive explosion of the second wave after the summer period when the infection rates in much of Europe had dropped drastically during the summer months. In autumn and winter we spend much more time indoors and this increases the risk that we get in contact with an aerosolized version of the virus.
Face masks which conform to the FFP2 norm are effective in preventing this type of contact with the virus. This is especially important in public places where social distancing is difficult, such as supermarkets, shops, schools, public transport or work.
Who should not wear an FFP2 mask?
Children younger than two years, people with respiratory problems and persons who are not able to take off the mask themselves should not use a mask.
How to put on an FFP2 face mask?
Step 1: Clean hands with soap and water or with a disinfectant gel.
Step 2: Ensure that nose and face are covered by the mask and there are no open spaces between mask and face.
Step 3: Prevent touching the mask during use. Infected particles may stick to the surface. Should the mask be touched, wash/clean hands immediately..
Step 4: Replace the mask when it gets damp/moist. Or if breathing becomes more difficult. A damp/moist mask is not effective. Do not re-use masks marked 'NR' ("Not Re-usable").
How to remove a face mask?
Step 1: Remove the mask by holding it at the straps
Step 2: Dispose of in a sealed waste basket.
Step 3: Wash/clean hands after use.
How to use a face mask?
Most important is for the face mask to provide a seal for the air going in and out of our body while breathing. Since the air needs to be filtered before inhaling and after exhaling, it is important that the mask has a tight fit around the face. Please ensure a proper fit. Also use the adjustable nose clip for a perfect fit.
It is important to not touch the mask during use. Before and after use, wash/clean hands thoroughly. After use, dispose of in a sealed trash can.
Attention: facial hair such as a beard can cause a less than optimal seal with the mask and may cause the mask to be less effective.
How long does a face mask offer protection?
It is not recommended to use the FFP2 mask for more than 8 hours continuously. In the following cases, it is advisable to replace the mask more often:
1) Breathing becomes more difficult.
2) The mask is damaged
3) The mask has gotten damp/moist
Please remember to order sufficient masks.
Attention: most/damp and/or damaged masks do not offer protection.
Is re-use of an FFP2 mask safe?
We advise to replace the face mask at a minimum every 8 hours. If the mask is used during the treatment of infected persons then it is recommended to change the mask immediately after the treatment. FFP2 masks witht 'NR' (not re-usable) behind the type indication are not meant for re-use. In case an 'R' (re-usable) is shown, then the mask can be reused subject to the recommendations in the manual.
How to clean a face mask?
Possibilities to desinfect face masks is being investigated. The results of this are not yet known.
How to use a face mask during a cold/flu?
Using a face mask while suffering a cold or the flu is a very social thing to do. It prevents viruses or bacteria infecting others around you. Follow the regular instructions for use.
Can a face mask be returned?
Any face mask can be returned within 14 days when unused and in the original packaging. Masks are a hygienic product which cannot be returned after use.
