Remove areas< 1 acre?  Maybe a majority filter with prejudice?

I have a huge raster (<300,000,000 cells) broken into 5 values I would like to eliminate zones which are smaller than 1 acre.  It was suggested that I convert them to a .shp and use the eliminate tool, this would just merge the smaller zones into larger ones.  The size seems prohibitive though, I doubt it would function at all as a .shp.  Is there a way to do this and keep it in a raster?
