Researchers have found that there are two types of cells inside the nose that are the likely entry point for the COVID-19 virus. These cells work as “viral entry receptors” and are highly accessible to the coronavirus because of the location in the nose. (Sungnak et al. 2020)
This developed the idea of a nasal protection device that could reduce the exposure to viruses.
In 2021, NOSA launches NOSA control – a medical device that reduces the amount of viruses entering the nose in the air inhaled.
Tests by external laboratories have shown that NOSA control can reduce up to 93% of Coronavirus, Rhinovirus and Norovirus when in contact with the device. A reduced exposure of viruses has been shown to reduce the risk of respiratory infections.
