It's a nonlinear spatial filter that generally gives an overall lowpass effect. Ideally it removes noise without attenuating high signal frequencies (thus preserving edges), but I was never fond of the result myself. The result is often too smooth. YMMV. What I'm suggesting is a linear (pseudo-)shift-invariant lowpass spatial FIR filter. The simplest way is just to filter the columns and then filter the rows using a 1D filter.
