The requirement to carry a mask with us when leaving our homes has made it difficult to find one's way through the plethora of masks that have been flooding the market for several months. Moreover, standards in this area are still relatively unclear at the national level.
Some models of these so-called "community" masks claim to be certified even though they don't really meet standards, "but that's not the case with KT Care's latest mask," explains Babette Keller Liechti, president of Keller Trading, a company specializing in microfibers based in Biel, in the canton of Bern.
"These labels require materials without the addition of harmful chemicals, with a filtration level of at least 70% for aerosols with an average size of one micrometer. We have achieved a score of 74%," stresses Babette Keller.
Microfiber for sustainability
The founder of KT Care points out that these masks are not made with conventional textiles, but with microfiber. "These are polyester microfilaments that form a tightly knitted yarn. We have added silver fiber, which is known for its resistance and antibacterial properties. The problem with natural textiles such as cotton is that they are almost always treated with pesticides, which is not good for the environment or for health."
Currently, only two so-called "community" masks are certified in Switzerland : the Everyday 2.0 from KT Care and one from the company Jakob Schläpfer.
Moreover, the Biel-based company's solution is more cost-effective, with an annual total cost of CHF 43, compared to an average of CHF 438 for an average of two disposable masks used on a daily basis.
In line with this sustainability approach, the company promises to work on a future recycled polyester version of its mask for even more environmental friendliness.
