"WebFirst, it seems wrong to say that filters are a generalization of nets -- in one sense they are equivalent to nets, and in another sense nets are the more general object: if one passes from a filter to a net and then back to a filter, one gets the original filter back again, but this is not the case for nets: the nets on a set form a proper class.
