I just got a stove installed last month and bought a quarter ton of a few brands to compare. I'm nearly done burning one brand, Clean Burn, made in tacoma washington and I seem to be having some breathing issues. The other two I bought lignetics, (which was super dirty) and Golden Fire (100 percent douglas fir which I bought an additional ton of and is awesome) I had 0 issues with. Has anybody else ever have breathing issues or allergy issues with one type of pellet or another? I can't find the exact type of wood clean burn is to know, but it smells pine like. I'm not aware of anything in allergic to but for the past couple weeks burning it I've been suffering a bit.
