You really only need one sifter, I think the ones I posted above are a set. You search on Amazon, I think I paid about $13 for the one I have. I also use it to make blends. I use a big tumbler cup and scoop up charcoal and then a scoop of Competition blend and it makes a nice comb of 50/50.wow thanks for posting that I am going to have to get one of those sifters now I had no idea of the danger.
FYI--In a humid environment, the sawdust buildup will clog up the auger system.
No. Just picked up on it while "listening" to other users via YouTube videos. I have only used the PB pellets, and notice the difference among different varieties within their company, some worse than others.
