Danyang Xunda Smoking Set Co., Ltd. (named Danyang Xunda Tools Factory before) is a professional enterprise specializing in design, development and manufacture of smoking sets. Our company was set up along with the reformation and grows under the condition of quick development of national economy. In recent years, starting with the improvement of management, we are expanding marketing network, perfecting after-sales services and creating new products. Our cigarette filters and holders are well appreciated and loved by consumers. If you can't quit smoking, by regularly using this filter you can reduce the tar, nicotine as well as many other harmful substances in the cigarette that you inhale at each puff. By reducing your nicotine intake, you can also reduce your nicotine dependency to help you to quit. The black-brown deposit trapped in the filter that would otherwise stick to your teeth, mouth, throat and lungs is clearly visible in the deposit chamber. The filter should be disposed after 5 to 10 cigarettes when the color mark is completely covered. If you are interested in our products, please feel free to contact us for more information. We are looking forward to cooperating with you in the near future.
