The Salin® Air Purifier works by having air constantly passing through the filter with micro-crystalline salts which creates a fine, constant spray of salt particles in the surrounding area. This unique dispersal of salt into the atmosphere offers long lasting and gentle relief from respiratory symptoms, without the use of a mask or inhaler. The Salin Plus Air Purifier is simply turned-on and left to work overnight. Whilst you sleep the salt diffused air is then inhaled, reducing inflammation in the whole respiratory tract; absorbing any swelling from the linings in the airways, widening the airway passages, unclogging mucus and congestion in the bronchi and bronchioles. By dissolving and freeing the mucus, Salt Therapy can cause an increase in mucus expulsion. This action restores normal transport of the mucus and helps to eliminate foreign allergens such as pollen or dust particles. Regular and sustained use of the Salin Plus Air Purifier can also slow down the development and build up of mucus reoccurring.
