The idea behind The Filter was devised by musician and digital pioneer Peter Gabriel and software entrepreneur Martin Hopkins.

(Modern game consoles solve this problem by pre-filtering the 480i video to a lower resolution. For example, Final Fantasy XII suffers from flicker when the filter is turned off, but stabilizes once filtering is restored. The computers of the 1980s lacked sufficient power to run similar filtering software.)
The filter was popularized in the field of economics in the 1990s by economists Robert J. Hodrick and Nobel Memorial Prize winner Edward C. Prescott.
Alex Strong and Kevin Karplus realized that the Karplus-Strong algorithm was physically analogous to a sampling of the transversal wave on a string instrument, with the filter in the feedback loop representing the total string losses over one period.
The Microparticle Performance Rating (MPR) system rates an Air filter’s ability to capture the smallest airborne particles—from 0.3 to 1 µm in size from the air passing through the filter.
The 13 Group HQ was at Kenton, near Newcastle upon Tyne with the Filter Room at nearby Blakelaw Quarry (not Blakelow, as erroneously mentioned previously).
The précieuses remembered through the filter of Molière's one-act satire of them in Les précieuses ridicules (1659), a bitter comedy of manners that brought Molière and his company to the attention of Parisians, after years of touring the provinces, and attracted the patronage of Louis XIV; it still plays well today.
Because most of the filter primitives represent some form of image processing, in most cases the output from a filter primitive is a single RGBA bitmap image (however, it will be regenerated if a higher resolution is called on).
