The filter paper can be drilled.
To prepare a filter paper for filtration, first fold the filter paper in half and then in quarters. Next, open the filter paper to form a cone shape and place it in the filter funnel. Wet the filter paper with a small amount of the solvent being used for filtration to help it adhere to the funnel.

Ash-less, hardened filter paper is made from high purity cellulose, sometimes washed with HCl and then with HF to remove minerals, and leaving ultra pure cellulose so when the paper ignites it burns completely leaving no ash. the hardening is achieved by washing the paper in nitric acid, which converts the cellulose to nitrocellulose which have more mechanical resistance and is also acid resistant.
Banana leaves do not resemble filter paper.
