The sterifilt has a polypropylene membrane that filters much more effectively than makeshift filters (such as cigarette filters) and is much less likely to be shared because it:

This means that the sterifilt has significant potential to reduce the soft tissue infections and other problems arising from the re-use of dirty filters.

Filters that have been contaminated with blood may also a hepatitis C infection risk, although this is much less than from shared syringes providing filters reinforces the importance of not sharing.
