Filtration

Basic concepts

• Coffee filters are a widely-produced commodity, and so are very cheap.
• Laboratory filter paper ^[?] comes in a variety of pore sizes, with some very technical attributes. [1] [2]
  • Vacuum filtration is regularly used in the laboratory, since gravity filtration can be too slow.

• For industrial-scale filtering, a filter press ^[?] is used. [1] [2] [3]
• Fryer oil filters are used for filtering fryer oil.
