Niko Stop Cigarette Filters are disposable filters designed to reduce the intake of tar and nicotine when smoking cigarettes. These filters are typically attached to the end of a cigarette and help to trap harmful substances, providing a smoother and potentially less harmful smoking experience. Niko Stop filters are often small and discreet, making them convenient for use on the go. They are a popular choice among smokers looking to reduce their tar and nicotine intake without giving up smoking altogether. However, it's essential to note that while filters may reduce some harmful substances, smoking still poses significant health risks.
