KINGFA has established a vertically integrated supply chain, from the upstream production of polypropylene, the midstream production of melt-blown nonwoven fabric to the downstream production of face masks. KINGFA provide wide range of face masks such as: Medical Face Masks (Type I), Surgical Face Masks (TYPE II/llR,LEVEL 1/2/3), Particle Filtering Half Masks (FFP1,FFP2,FFP3)
All FFP masks must be tested and must filter out varying amounts of the test aerosols. FFP1 masks must filter out at least 80%, FFP2 masks at least 94% and FFP3 masks 99% of test aerosols. Testing is performed in line with the European standard EN 149:2001+A1:2009 with aerosols and ensures that the FFP masks available on the market fulfil technical norms and have proven to protect against aerosols.
Face masks and barrier face coverings should generally be used for source control, meaning they may help prevent people who have COVID-19 from spreading the virus to others. These products may also help limit exposure to respiratory droplets and large particles but are not a substitute for filtering face piece respirators or surgical masks.
Two important ways to make sure your mask works the best it can.
1. Make sure your mask fits snugly against your face. Gaps can let air with respiratory droplets leak in and out around the edges of the mask
2. Pick a mask with layers to keep your respiratory droplets in and others’ out. A mask with layers will stop more respiratory droplets getting inside your mask or escaping from your mask if you are sick.
1. Flammability: this tests how likely the material is to burn and spread flames.
2. Breathability: This test measures the resistance to airflow
3. Particulate Filtration (PFE) : This represents the percentage of submicron particles filtered at 0.1 microns by the mask
4. Bacterial Filtration Efficiency (BFE): This tests measures what percentage of bacteria at a size of 3 microns are filtered by the mask.
5. Fluid Resistance: This test checks the ability of the mask’s material to minimize fluids from traveling from the material and coming into contact with the wearer.
FFP mask (“Filtering Face piece Particles”) is an individual respirator protection mask. Developed as per standard EN149, it is designed to protect the wearer against the inhalation of both droplets and particles suspended in the air.
1.FFP1 masks which filter at least 80% of aerosols (inward leakage < 22%);
2.FFP2 masks which filter at least 94% of aerosols (inward leakage < 8%);
3.FFP3 masks which filter at least 99% of aerosols (inward leakage < 2%).
Type I, and Type I R face masks have a BFE (bacterial filtration efficiency) of 95%, whereas Type II and Type II R face masks have a BFE of 98%. The breathing resistance, and splash resistance for Type I R and Type II R masks, are exactly the same.Type I, I R, II and II R face masks are medical masks tested in the direction of exhalation (inside to outside) and take into account the efficiency of bacterial filtration. Surgical masks of this type stop the wearer from infecting the surrounding environment. They are not effective at protecting the wearer from airborne diseases such as coronavirus.
ASTM International considers the aforementioned performance tests when rating a mask’s performance. There are three numerical ratings they assign which can be summarized as the following:
Level 1 – Low barrier protection
Level 2 – Moderate barrier protection
Level 3 – Maximum barrier protection
