The Vita Shield has demonstrated 90% Bacterial Filtration Efficiency (BFE) when tested in accordance with EN14683 (Medical face masks – Requirements and test methods). This result exceeds the specification set in the Belgium and French standards for community masks of >70% BFE.
Vita Shield has passed the CWA 17553:2020 (European workshop agreement for face coverings) from the independent test house, Centexbel. During testing, our face covering filtration efficiency for 3 micron particles was recorded at 98% compared to the minimum pass rate of 70% and passed the air permeability (or breathability) at 319 l/(m2/s) compared to the standard requirement of >96 l/(m2/s). The filtration efficiency test simulated the wearer’s experience of exhaling droplets and aerosol particles that may spread the virus by capturing these when we cough, sneeze or talk, while the air permeability test demonstrates the face covering allows the wearer to breathe easily.
The test requires the face covering to be washed and dried after its initial test and then retested, to ensure re-use claims. Our Vita Shield face covering retained 98% filtration efficiency, showing no reduction in performance.
The advanced polymer used for these face coverings is from a range of polyurethane foams selected and approved for use in hygiene applications and is tested extensively in the UK and Europe for volatile organic compounds (voc) to ensure that the cleanest products possible are used. Vita Shield face coverings are produced in a range of sizes. Please refer to health authority and government guidance on suitability of face coverings for children and vulnerable people.
It is a scientific fact that experiments have shown that wearing a face covering properly can significantly reduce the droplets and aerosols ejected from a person’s nose and mouth. When you wear a face covering that fits properly, little or no droplets are released into the atmosphere when you cough or sneeze. It is important to wear a face covering properly to reduce the potential spreading of the virus. Many Countries have made the wearing of face covering mandatory, or highly recommended, although views are still being formed. For Country specific guidance we recommend you consider the guidelines issued in your country of residence. Vita Shield is not a medical device or personal protective equipment (PPE). This product is not packed in a sterile environment.
Face coverings are considered personal items which are sealed for health protection and hygiene reasons, and as such may not be exchanged or returned for re-sale where they have been unsealed following delivery. Face coverings will be replaced only if defective in description, materials or construction.
This is not PPE and does not replace any PPE you are required to wear in your workplace.
Please check your government and local heath authority web site for the latest information.
For some people with asthma, wearing a face covering might not be easy and could make it feel harder to breathe. Please check government and local health authority guidance.
Breathability is the ability of a material to allow moisture vapour to be passed through the material. The higher the breathability the more can pass through and the more comfortable the face coverings is for the wearer.
