Bob's Red Mill cereal

Question

Bob's Red Mill gluten free cereals. They manufacture several lines of cereals that have no Hametz on the label, and some of them are labelled "gluten free", such as their brown rice cereal. Can we use the ones labelled "gluten free" for Pesah? What about the ones not labelled "gluten free" that only list non-Hametz ingredients?
