The Clever Coffee Dripper combines the best features of French press and filter drip brewing, eliminating the drawbacks of each. With French press brewing, you can control steeping or infusion time, but heat loss and sediment in the cup can be a problem. Brewing with a paper filter is easy and convenient; the problem is lack of control over steeping time (i.e. the coffee begins to drain immediately). By adding a stopper to a filtercone, the Clever Coffee Dripper combines control over steeping time with a sediment-free cup.
