We have been using a the Salin® Plus Air Purifier for a few months now and the change in my sons asthma is amazing. Dylan was being admitted to hospital every 3-4 weeks due to his severe asthma. Since using the Salin® Plus he has not been to hospital or doctors. His asthma symptoms are practically non-existent and he had not had any difficulty in breathing since using this product. It has changed my son’s life in such short space of time after suffering since he was 8 months old.
