prefiltered
Cleaned before use
Prefiltered describes something that has already been filtered before reaching its current stage.
Water may be prefiltered to remove large particles before finer purification.
In computing, prefiltered data has been screened before processing: The prefiltered results load faster because irrelevant entries were already excluded.
The prefix emphasizes that filtering happened earlier in a sequence.
