Diffuser device, system and method

A diffuser device for diffusing exhaled vapor that is inhaled from a vaper producing device, the diffuser device comprising:

• a first tubular portion including a length and a first interior surface defining a first bore extending through the first tubular portion along the length, the first interior surface defining a first ledge;
• a second tubular portion including a second interior surface, the second interior surface defining a second bore, the second tubular portion removably and rotatably coupled to the first tubular portion such that the second bore is coaxial with the first bore;
• and
• a removable, disposable filter having a cylindrical structure sized to be positioned within the first bore between the first ledge and an end of the second tubular portion.

A method of diffusing exhaled vapor that is inhaled from a vapor producing device, the method comprising:

• providing a diffuser device including a first tubular portion rotatably coupled to a second tubular portion with a disposable filter positioned within the first tubular portion such that the first tubular portion is coaxial with the second tubular portion and such that the filter is positioned and secured between a ledge defined by an interior surface of the first tubular portion and an end of the second tubular portion;
• inhaling a vapor from a vapor producing device;
• and
• exhaling the vapor through one end of the first tubular portion such that the vapor is diffused by the filter positioned in the first tubular portion so that air passes through the filter and vents from the second tubular portion.
