@RexRed,
honey is the ripened nectar.Pollen is pollen. The two , together as a colloidal suspension should NOT define honey. Whether bee pollen is actually an effective anything is not settled science.
A number of people are actually allergic to pollens and in increasing severity. Im not certain thats why they filter it, but when we raised bees we would ultra filter some and sell it as pollen-free honey. Having the FDA take it upon themselves to redefine honey if and only if it contains pollen (and it probably also contains quite a bit of bee ****), that's incorrect and base upon your posts Ive contacted our local Apical sciences at Penn State with the question.
0.4 microns is pretty small and would remove about 99.9999% of the pollen bits nd most all the bee **** , mites etc.
Its kind of like when food prep firms started advertising "PENUT FREE" stuff
