Our donut-shaped filters for Suka Pipe give you a smoother hit as well as capturing tar in it's 100% polyester fibers.  This set of five filters actually has ten donut pieces, because two donuts fit into one Suka Pipe.  You can also rotate the round filters, flip them upside down, or switch top and bottom, to get full use out of them.  They will however eventually fill up with tar and need replacement.  

If you don't like to cough during a pull, are a beginning smoker, or just prefer gentler hits, these filters may be for you.  If you are a veteran smoker who likes the 'choke', or just prefer a harder hit, then these filters may not be for you.  It's all about preference.
