Using fuzzy filters in the sense of P. Eklund and W. G\"ahler [2] in fuzzy preuniform
convergence spaces as introduced in [11] compactness and weak compactness are presented 
by means of convergence and preconvergence of fuzzy ultrafilters respectively. 
The generalization of these concepts by localization leads to bicoreflective  subconstructs 
of the construct of \textbf{FPUConv} of fuzzy preuniform convergence spaces 
which are additionally cartesian closed. 
These results are even new in the non-fuzzy case (i.e. in the realm of preuniform convergence spaces) 
which is included and improve the situation for topological spaces.
