Removable filter for a smoking pipe

A filter kit comprising:

• a screen;
• a staple in the form of a letter shape U comprising two parallel pins spaced a first distance, connected at one end by a central curve;
• wherein the two pins are adapted to puncture the screen, creating two holes in the screen, spaced at the first distance, through which the pins pass, when the staple is pushed with average adult human fingers into the screen;
• wherein a portion of the pins of the staple that have passed through the screen are adapted to be splayed apart by average adult human fingers such that the ends of the two pins are then separated by a second distance, larger than the first distance;
• wherein the screen is adapted to be placed into a smoking pipe bowl with an orifice, wherein an inside of the bowl and an inside of the orifice are fluidly connected;
• and
• wherein an inside diameter of the orifice is smaller than an inside diameter of the bowl;
• wherein the screen is adapted to block solid particles from the smokable charge from passing through the screen while permitting smoke from a burning charge to pass through the screen into the orifice;
• and
• wherein the screen, staple, bowl and orifice are adapted so that the screen and staple may be removed from the bowl by grasping and pulling with an average adult human thumb and forefinger a portion of the staple above the screen.
