In order to maintain taste richness while reducing harshness, certain "filter-insert" and filtered Wooden cigar mouthpieces designs place a filter element inward from the tip, allowing smoke to still travel through extra tobacco.

Although they have little influence on gasses like CO, filters (in general smoking goods) can lessen the "harshness" of particulates and keep tobacco particles out; users of filtered formats frequently report smoother, less unpleasant pulls.

In order to chill the smoke and minimize some dangerous compounds, some mouthpieces and regional cigar shapes (like Toscano accessories) advertise filter alternatives; the precise reductions vary depending on the filter material and arrangement.

Filtered formats can feel softer and lessen coughing for novices or people with sensitive throats, but they can also lessen the intensity that connoisseurs occasionally like in premium long-filler cigars.
