Solution:
The above statement is true.Filtration is the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles.
Both filter paper and cloth contain pores which are used for filtering. The pores of clothes are larger, due to which particles of sand may pass through the cloth to filtrate. At the same time, the pores of filter paper are microscopic. Due to this, sand particles do not pass through it. That is why filter papers are used.
