How to Clean Cigarette Filters

Unscrew the cigarette filter from the o-ring. The o-ring is the portion on the filter which fits over the cigarette.

Fill a bowl with warm water and a squirt of liquid dishsoap. Place the filter in the soapy water and allow it to soak for five minutes.

Lift the filter from the soapy water. Insert the wire-end of the filter cleaning brush into the filter to clean the mouthpiece. Use the soft-end of the brush to wipe down the outside of the filter and the o-ring.

Rinse the o-ring and filter under cool running water to remove all soap residue. Allow the pieces to air dry prior to using.
