Smoking pleasure with less pollution - scientifically inspected!
The microfilters from David Ross are used as a mouthpiece on the filter of a cigarette and reduce up to 60% of tar and nicotine of the smoke that you inhale. This works due to the physical Venturi-principle, in which a negative pressure is created inside the filter. Thanks to this negative pressure, a part of the tar particles and other noxious substances is pressed to the inner wall of the filter, remains stuck there and doesn't get into your lungs.
Each microfilter can be used for approx. 5 cigarettes. As soon as the transparent plastic turns completely black from the inside, the filter should be disposed and replaced by a new one.
The David Ross filters are hygienically wrapped in bundles of 5 and can be taken separately from a blister pack.
