I use a kitchen sieve to remove 'lumps' of wax. Even so, that may remove some pollen as the mesh becomes reduced by clogging.
The 75 micron will remove quite a lot of pollens; the majority, I would think, use the 200 micron for most purposes. 75 microns will give a 'brighter finish' - useful for the honey shows
.
Removing more pollen may lengthen the time for the initial onset of granulation (for any given floral type).
I dont think there is so much pollen greater than 200 microns. Your hayfever is likely caused by much smaller pollens (airborne) and if true 'hayfever' will be caused by the very small pollens from grasses - which bees do not collect.
I am quite happy to perpetuate the idea of eating pollen (in honey) to reduce the effects of hayfever, but I think in most cases it is likely the wrong pollen at the wrong time with an effect on the digestive, rather than the respiratory, system.
Time is also a factor under the same filtering conditions - the smaller the aperture, the more difficult to filter. 200 microns is the size I use, and at that size I reckon I can claim relatively unadulterated honey as the finished product.
Hope that helps.
