FFP3 face masks, also known as N99 masks, are form of Personal Protective Equipment (PPE), which filter up to 99% of particles from the air. They provide protection to the wearer from viruses, bacteria and other harmful particles in the air. FFP3 masks provide the same amount of protection as each other, but have different names depending on where they have been made. These masks are commonly used by those working in the healthcare industry and are now being used by the general public to provide a higher level of protection than other masks. The “N” in N99 stands for “not resistant to oil”, and “FFP” stands for “Filtering Face Piece”. These PPE face masks are resistant to fluid and have been approved by the World Health Organisation for preventing the transmission of COVID-19.

FFP3 masks have a filtration rate of up to 99% and have 5 layers of protection. They are more effective than other respirators such as N95, FFP2, FFP1 and surgical masks. Whilst many healthcare professionals use FFP3 masks, our masks are not intended for use by medical professionals.
FFP3 respirators cover the mouth and nose area. They have two elastic headbands which go over the head, or the ears to keep the mask securely in place. They are fitted with a metal strip which can be adjusted to secure a tight fit around the bridge of the nose, preventing air from entering through the sides of the mask. Please contact us if you require a specific type of mask.
FFP3 masks are not usually reusable and should be disposed of after one-time use. Most respirators will be marked with the letters “NR”, which stands for “Not Reusable”. This is because infectious particles are not visible to the naked eye, and it is not possible to tell if your respirator is contaminated. If you wish to reuse your face mask, you should look to purchase reusable face masks.
If you wish to reuse your face mask, there are a few points to consider:
FFP3 masks are not washable. High heat and certain liquids can destroy the structure of the mask, making them ineffective. If your respirator becomes infected, you should discard it and use a new one.
FFP3 respirators are made of fine tangled fibres, creating a difficult path for small particles to travel through. This structure leads to particles being caught by the fibres, so they are unable to reach the mouth and nose. For a face masks to be effective, these pathways cannot be too small as they would make it difficult to breathe. At the same time, they cannot be too big, as this would allow all particles to pass through. These masks also exhibit electrostatic absorption, which is where electrostatic charges attract very small particles to the fibres of the mask. FFP3 masks are also fluid resistant, so fluid will not absorb through the mask, offering a high level of protection. FFP3 masks are designed in a way to allow the user to breathe, whilst providing a high level of protection from airborne viruses, such as coronavirus.
You can use these respirators for up to 8 hours. However, if you remove your mask or suspect that it has become contaminated, you should discard the respirator and use a new one.
FFP3 masks with a valve contain a small plastic structure, which allows small amounts of air to be released, without allowing any air into the mask. These masks provide protection to the user but offer limited protection to those around them. These masks are predominantly for use by those with breathing difficulties, such as asthma, COPD and cystic fibrosis.
There is no difference between N99 and FFP3 masks, as they both offer the same level of protection. The difference in name is due to different codes depending on the country in which the masks were manufactured. N99 equates to FFP3 in the same way the N95 equates to FFP2. The difference between FFP1, FFP2 (N95) and FFP3 (N99) respirators are the number of particles which they filter. N99 respirators filter up to 99% of particles, providing the highest level of protection, followed by N95 or FFP2 masks, which filter up to 95% of airborne particles, and FFP1 masks, which filter around 80% of particles.
To find out more information, you can read our article about the difference between FFP3 (N99) masks and FFP2 (N95) masks.
These masks are not designed to fit the face of a child. If you wish to purchase a face mask for a child, you should look for specific children’s face masks.
Masks with headbands generally provide a tighter and more secure fit. They form a seal around the face, minimising the chances of your mouth and noses from coming into contact with airborne particles.
A duckbill FFP3 or N99 mask resembles the shape of a duck’s beak. They offer the same level of protection as the standard flat folded mask; except they cover a wider surface area of the face. These masks offer a good fit for those with a larger face size.
To ensure maximum protection, you should ensure that you wear the FFP3 respirator correctly. This is to avoid cross contamination, and to ensure that there are minimal gaps to reduce the risk of infection. You can see “how to wear an FFP3 mask” under our instructions tab.
UK Guidelines state that FFP3 masks are the recommended masks for use by NHS professionals, who are at medium to high risk. These respirators are predominantly used by staff who work in hospitals, such as nurses and doctors. This is because they offer the highest level of protection to the wearer. Research suggest that if worn correctly, FFP3’s can provide up to 100% protection.

Cup the respirator in your hand ensuring that the nose-piece is at the top and the headbands are hanging freely
Position the respirator under your chin with the nose-piece resting on the bridge of your nose
While holding the respirator in position, place one loop over your head
Still holding the respirator, place the other loop over your head
Using both hands, adjust the malleable nose-piece so that it fits snugly against the bridge of your nose and face
Using a mirror, check to ensure that all of the edges provide a good seal around your face
