This is the first year that my girls produced enough honey to harvest so I'm getting everything together. Out of my six hives, I have two that produced a surplus. My question is about the different filtering systems. In the new Brushy Mtn. flyer they have the 5-gallon filtering system and the stainless steel double sieve on sale. Would I be able to use just the 5-gallon filter or do I also need to get the double sieve to adequately filter the honey? I'm trying to save a little money and don't want to buy more than I need at this point.
