Filter Press or Lenticular Housing? Pros and Cons

Filter presses and lenticular housings are both solid equipment options that can handle small and large volume filtration jobs. Both are utilized in beverage, food, industrial, and pharmaceutical processing. The initial upfront equipment costs for each are comparable. However, the final cost will depend on the size and features of the equipment. Each option has pros and cons.

Filter presses work with a full range of filter media and are an economical choice for most filtration applications.  The size and dimension of the press plates determine the size and dimension of the filter sheets that can be used.  Most popular are 40 cm and 60 cm presses, although hundreds of variations exist. 


  • Full range of filter media available, including media embedded with active carbon.
  • Filter sheets are lower in cost per square foot of media compared to lenticular filters.
  • Sizesrangefrom small benchtop presses to units that can take up an entire room.
  • Multi-step filtration can be done in the same press with use of a crossover place, e., filtering through a coarse sheet and then through a polishing sheet.
  • Consistent performance.
  • Can be very cost effective, gains in efficiency can be made through optimization.


  • More time needed to load/unload
  • Can take up a larger footprint and requires more room than a lenticular housing.
  • Not enclosed.
  • Wicking or dripping.

Lenticular filter housings also work with a full range of filter media, including carbon embedded media and are great for filtering high value material.  Lenticular filters are made up of pre-assembled “stacks” of filter sheets that have been molded together using plastic. These filters provide a larger amount of filtration surface area in a compact form, but they are more costly per square feet than filter sheets.


  • Full range of filter media available, including media embedded with active carbon.
  • Easy to load.
  • Housings are available in different diameters and height configurations.
  • Smaller footprint due to its vertical orientation.
  • Enclosed unit offers a more sanitary filtration and less product loss.
  • Short term storage of filter media in between uses maximizes the life of the filter media.
  • Consistent performance
  • Efficiencies can be gained through optimization.


  • Lenticular filters are more expensive more per square feet of media than filter sheets.
  • Larger housing units may require additional equipment to safely lift the housing dome.
  • More waste disposal from more components within the lenticular filter.
  • Sensitive to backflow but easily avoided with a check valve.
  • Some units are limited to use with manufacturer specific filters.
