The conical and the fluted papers employ the gravitation technique in the filtration process.

The conical filter method entails folding the filter paper into a cone and inserting the cone into the filter funnel. The fluted filter method entails folding the filter paper into a fluted filter.

With the use of the conical filter paper, the solvent may form a seal between the funnel and the filter paper, preventing displaced air from escaping and considerably slowing down the filtration process.

The fluted filter paper, on the other hand, allows air to enter the flask along its sides to equalize pressure, thereby increasing the speed of filtration. The fluted filter paper also provides a larger surface area through which the solvent can seep. These two factors expedite the filtration process when the fluted filter paper is used instead of the conical filter paper.
