Description
The XTRM MAXX filter is designed to force someone to breathe exactly what you specify. Red and black, solid, two-piece - a filter that immediately makes it clear who decides and who follows.
You can either play with the standard version - black container, direct draught - or you can add the red intermediate piece and turn it into the double version. More volume. More control. More influence on every breath.
What do you insert? It's simple: whatever your session requires. Socks, leather scraps, rubber, soaked absorbent cotton - you determine the resistance, you determine the intensity, you determine how much someone can feel that every breath is coming from you.
