One filter for 3-7 cigarettes This product will not repair damage to the lungs..It has been proven that with the constant use of the TARBAR filters ,much of the harmful substances will REMAIN in the FILTER and not enter your LUNGS. SCIENCE.....With inhalation the smoke is fed into the filter and forced through the 6 pinpoint holes creating a circular motion with wind speeds in excess of 200 mph. The centrifugal force pushes much of the impurities to the sides of the filter preventing them from entering your lungs.
