    How does NOSA bacterial control work?

    NOSA bacterial control is placed in the nostrils so that you can breathe through the product. The product design forces the air to pass through the device where the bacteria gets in contact with the lamella structure that captures and inactivates the bacteria. This is possible due to the unique silver ion substrate inside the lamellae structure.

    In this way, the device reduces the amount of bacteria that enters the respiratory system. NOSA bactrial control is a medical device class 1 and is available within Europe.

    Why NOSA bacterial control?

    For several years NOSA have been working on a solution that can reduce the amount of viruses and bacteria in the air we inhale through the nose. Research has shown that virus and bacteria often spread and infect through the upper respiratory tract through the sensitive mucous membrane in the nose. Since the outbreak of the Covid-19 pandemic, NOSA worked even harder to offer a solution in the time when it was needed the most. In 2021 NOSA control was launched, a product family that reduces the amount of viruses and bacteria in the air inhaled through the nose. NOSA bacterial control is tested against several common bacterial strains, such as staphylococci, pneumococci and e-coli. In hospital environments these bacteria can cause serious harm to patients and staff, especially to people with a reduced immune system.


    Both virus and bacteria are often called microbials, and are of microscopic size. Viruses are much smaller than bacteria and unlike bacteria, can’t survive without a host. Viruses are not living organisms and reproduce by attaching themselves to cells. Most viruses can cause disease and are often attacking specific parts of the body, such as the respiratory system. Bacteria is a bit different though since there are a lot of “good” bacteria that do not cause diseases. In fact, most bacteria are harmless, but there are some bacteria such as Staphylococcus, Pneumococcus and E-coli that can cause serious illness. (WebMD Medical Reference, 2021)


    Viruses mainly have a negative effect on the body since it often causes disease or illness, while bacteria can have both a positive and negative effect on the body. Some “good” bacteria are even crucial for our survival, for example the bacteria that already exist in our digestive system. But there are also bacteria that makes us sick, for example Staphylococcus (MRSA) which often exist in the nose or other membranes. (WebMD Medical Reference, 2021)

    The most common virus is the Rhinovirus, which causes cold. There are also other types of more serious virus-diseases, for example the Coronavirus. (Kry, 2020)
