A comprehensive test of the nine engangsmundbind and six reusable stofmundbind, as the Danish Technological Institute have carried out for Politiken shows that engangsmasker is better to filter particles from the than the stofmundbind, which is with in the test.
Stofmundbind vary so extremely in their filtreringsevne. It writes Politiken.
The slightest stofmundbind in the test is a design-mundbind from a large fashion company. It filtered only 23 percent of small dråbepartikler and 58 percent of larger dråbepartikler from.
Mundbindet is so popular that it, according to the newspaper right now is out of stock due to high demand.
the Danish Technological Institute is a certified institute. It tests, among other protective equipment for enterprises and authorities. The institute must, for legal reasons not to disclose the names of the products.
For comparison, the filtered test nine engangsmundbind at least 97 percent of dråbepartiklerne from.
There must, however, be subject to the test is only testing the material. It tests not how mundbindene ends close in the real world.
Consultant and ph.d. Stig Koust Hansen from the Danish Technological Institute says to Politiken that 23 percent filtering is not sufficient.
- I do not believe that the 23 percent filtering provide enough protection. You can imagine that you put yourself in situations where you are close in the larger gatherings, because you think, mundbindet provides protection.
- I would not use it, he says to the newspaper.
You can also not count on a stofmundbind made of three layers is better than a mundbind with fewer layers. The general recommendation from the Danish Health and medicines authority is otherwise, you should use stofmundbind with three layers of fabric.
A mask with just one layer of cotton was tredjebedst among stofmundbind. It confirms many international studies showing that the quality of the material is of crucial importance, writes Politiken.
Friday night, the Parliamentary parties reached an agreement on the genåbningens stage 4. Here it appears that 'the government expects that the use of mundbind in the Danish society should be disseminated and made more uniform'.
According to DR's information will be the key message in the prime minister Mette Frederiksen press conference Saturday morning that all passengers must wear mundbind in the public transport in the whole country.
