Which is the most fitting word for the disposal of unnecessary data in a data set; filtering or filtration?

e.g. Log data filtering or Log data filtration?

  • I'd use "to screen data", with the "for unnecessary data" implied if you want to put the emphasis on the removed part (as in "screen people for disease")--> data screening. Or " to filter data" if you want to highlight the set kept-->data filtering

  • If you do a Google ngram search for (data filtering),(data filtration) you will see that data filtering is far more common, and that data filtration usually appears in texts that were authored probably by non-native speakers (judging by their names).

  • Thanks for your answers. One example: is "A proper filtering algorithm will save valuable information and discard the rest" preferred over "A proper filtration algorithm will save valuable information and discard the rest"?

1 Answer 1


Filtration is the process of separating solid/particles from fluids.

I would then go with filtering, though filter alone may do as well.
