I have never used the brand of cellulose insulation on the left, but I have purchased Green Fiber cellulose from Menard's when in a pinch last year. The quality was awful and it was not a 100% borate formula, smelled like ammonia, and a few bags where damp inside. With every bag I was amazed at how much junk was in the bag, and how large the pieces were.
