Salin Plus is an air purifier that uses micro-crystallized salt to remove airborne particles and pollutants from the air. It claims to help relieve respiratory conditions and promote better respiratory health. However, there is limited scientific evidence to support the effectiveness of salt therapy for respiratory conditions. Salin Plus claims that the micro-crystallized salt filter has the ability to break down and eliminate airborne bacteria and viruses. The device is also said to help relieve respiratory conditions such as asthma, allergies, and sinusitis by releasing tiny salt particles into the air. How to Use: Turn on the appliance by plugging it in. Ensure that the air intake is not blocked and that there is adequate ventilation in the room. Leave the device to run continuously for at least 24 hours for maximum effectiveness. Replace the filter every four to six months or as directed by the manufacturer.
