The CIVIS company, i.e. the occupational health and safety specialists, tested 15 different masks/materials and wrote an opinion about the SHIELD mask: “In some properties, the mask is comparable or even superior to a certified safety mask according to the EN 149 requirements.”
Our SHIELD reusable sanitary face mask performed great at the test. For this reason, we were contacted by CIVIS and we and our clients were offered professional cooperation. They produced very professional and precise instructions for natural and legal persons on the business conduct and operation during the SARS-CoV-2 epidemic (COVID-19).
In the tests performed with the basic water permeability criterion, only two masks showed a different result than almost complete permeability, namely the disposable mask (EN 149) and the SHIELD mask, which has a TPU membrane in the material. These two masks are the only ones tested that have not absorbed a drop of water on the surface within eight hours. The other masks absorbed the water within seconds. In their essence, the results of the test are unsurprising. Most materials the
“handy” masks are made of, such as cotton, paper and the like, are designed to absorb moisture. Of course, these materials perform this task very well, but the effect is unfortunately the opposite of what a proper mask should do, i.e. act as impermeably as possible.
It should also be noted that disposable masks are not intended for disinfection and are thus unsafe in reuse, so it would be wise to consider how much of the family budget you are prepared to allocate for face masks at the time of the SARS-CoV-2 (COVID-19) epidemic and pandemic. Provided they are used properly, a half-year cost for disposable masks, e.g. the certified FFP2 masks, comes to a staggering amount of €826.80 per person, or €360.00 per person, which is the same cost for
the disposable (EN 149) masks. The cost for the entire family is extremely high! You can save money by choosing a high-quality SHIELD sanitary face mask made of material that has been tested for moisture and liquid absorption.
The CIVIS conclusive opinion on our SHIELD sanitary face mask:
“The results of water and vapour permeability tests have shown that, in some respects, the mask can be compared or is even superior to the properties of a protective mask certified according to the EN 149 requirements, which is probably also related to the fact that the protective mask (EN 149) is intended for single use, while the SHIELD sanitary mask is reusable (provided that the maintenance and washing instructions are followed).”
