Traditional asthma treatment focuses its efforts on the symptoms, like so many treatments do. This treatment focuses on the causes instead, i e allergens in the air. The machine reduces the allergens so that the air you sleep in is practically free from them. Therefore you can relax without any symptoms and hopefully feel more rested in the daytime too. It is hard to function when you have difficulty breathing. This device is sheer brilliance and the many testimonies speak their own language to that, all in praise of this fantastic solution to an affliction.
