Salin and Salin Plus are innovative, award winning medical devices, designed for home or office use, that saturate the ambient air with a dry salt aerosol, by forcing air through a special micro-crystalline filter. When inhaled, the salt particles travel deep through the upper and lower respiratory tract. These microscopic particles have the effect of increasing the viscosity of the mucous and thus expelling it from the respiratory system, whilst also reducing inflammation. This has the effective of removing the harmful bacteria that leads to infection and increasing the airflow, thus improving breathing. The device has no side effects and is suitable for everyone.The special filter also works to collect and retain airborne pollutants such as dust, smoke, and odours, and thus improve the quality of the air you breadth.
