Re: How fine Do You Filter Honey?
Here is a bit of a different answer to the question. Also straining and filtering both are targeted at the same object. to remove unwanted particles. but they are different in the scale of particles they will remove as well as the mechanics of the process required.
I use these strainers of a purpose other than honey. One that actually allows you to see the size of particle that is passing the strainer mesh. 600 micron will allow a particle that is clearly visible to the naked eye and in fact would be felt on the tongue or mouth with ease. like a grain of sand. The 400 micron will allow only slightly visible and barely feel able particles to pass comparable more to flour. In my application these particles are so fine they cannot be dumped from a bowl from there own weight they simply cling to the plastic much like flour clings to everything it touches. I do not use the 200 micro in what I do but obviously there would be a comparable reduction in particle size. as was mentioned before you are getting down to pollen particle size.
