är combines the best technologies


ViralOff is a revolutionary treatment that reduces the presence of viruses on textiles by 99% within two hours. It has been tested against Influenza A virus subtype H3N2 and H1N1, BirdFlu, Norovirus, and Corona (SARS) - and 99% protection was achieved in every trial. In addition to that, ViralOff doesn’t interfere with the natural bacterial flora of your skin. It has been certified by ISO 18184:2019 and ATCC VR-1679 (H3N2) tests. The active ingredient is a biocide. Reaction mass of titanium dioxide and silver chloride.


The Eco Acqua Zero treatment of fabric makes the surface of the mask water repellent, causing water to flow off the material and not be absorbed (Note: this does not mean it works in heavy rain). It also helps remove water from inside the mask, transporting it to the surface where it evaporates. This fabric treatment replaces older methods that were not as environmentally friendly and could be harmful to the wearer’s health. Eco Acqua Zero is completely safe and provides the first line of defense for aerosols released during coughing, sneezing, and regular verbal communication.


Our är Facemask is one of the few products of its kind equipped with an exhalation valve in front of the filter. This means that you can relax and feel protected while knowing you are also significantly reducing the chances of infecting those around you because all the air you are breathing out passes through the nanofilter.


The top part of every är Nanofilter is equipped with an aluminum strip that lets you adjust the shape of the mask so that it sits on your nose perfectly. The foam along the edge of the nose piece makes it truly comfortable to wear while also preventing any leaks.


Nanotechnology filters block up to 99.98% of viruses, bacteria, dust, and other airborne pollutants and contaminants. Their ability to block common viruses of today has been proven by tests administered by Nelson Labs. Each filter comprises of three layers that create a high level of protection. The nanofibers within the filter, whose average thickness ranges between 100 nm - 500 nm, are 1,000 times thinner than a human hair! These fibres filter out biological contaminants such as viruses, bacteria, and pollution, while the porous weave means easy, comfortable breathing. These filters are replaceable, giving you a maximum feeling of protection. .


To ensure the highest level of comfort, är Facemask is fitted with a small buckle on each strap. This allows you to adjust the length of the straps for a snug fit over your ears, to make sure the mask covers your mouth and nose properly and fits your head perfectly.
