The key difference between Whatman filter paper and normal filter paper is that the Whatman filter paper is suitable for qualitative analysis whereas the normal filter papers are suitable for both qualitative and quantitative analysis.
Filtration is a technique of separating different components in a mixture. We can use filter papers for this separation. Therefore, we use it as a barrier that is perpendicular to either a liquid flow or air flow. Thus, these filter papers are useful for qualitative or quantitative analysis. Whatman filter paper is specific for qualitative analysis.

What is Whatman Filter Paper?
Whatman filter paper is a specific type of filter paper that is used for qualitative analysis. These filter papers contain cellulose fibers, and people manufacture them from high quality cotton linters (First, we have to treat them in order to increase the amount of alpha cellulose). Therefore, Whatman filter paper contains a high percentage of alpha cellulose. This gives it high quality and consistency. There are several grades of these filter papers. We can divide them into grades according to the particle retention, thickness, and weight. Ex: Filter paper grade 1, 2, 3, etc.
