Scientists from Imperial College London has invented a new device for air cleaning, which reduces symptoms in patients with asthma.
To test the device, the volunteers ( all testing was carried out 282 people with severe forms of the disease) report that they have experienced improved quality of life with this invention.
Dr. John Warner said: "This device is comparable in effect with long expensive treatment, so it helps to prevent disease".
Machine called protexo is placed on a bedside of the patient and provides a flow of clean filtered air around the head of the sleeper. The machine filters out the irritants and allergens that cause asthmatic reactions, including filtered dust mites and allergens from pet hair.
Specialists in asthma call upon, patients with severe forms buy cars, though the original cost of the drug is 6 thousand dollars.
