Filter paper disc is most frequently used in daily filtration, medium retention, and flow rate. Filter paper 1 is very widely used in laboratory applications to clarify liquids. Filter paper is typically used for quantitative analysis and separation of precipitates, such as lead sulfate, calcium oxalate, and calcium carbonate.

In agriculture, it is used for soil analysis and seed testing; in food, it is often used as a conventional method of separating solid food from related liquids and extracting liquids. Filter paper 1 is widely used for simple qualitative analysis separation in teaching. For air pollution monitoring, there are discs and roll types available. Atmospheric dust is collected from the airflow and then measured with a photometer; in gas detection, the filter paper is soaked with a chromophore and measured by light reflection.
