Keep your Arizer setup ready with this practical 50-pack of Go filter screens. Made from stainless steel, these screens provide filtration for Go Shells while supporting an open airflow. They are also compatible with Go Glass Aroma Tubes and Go Frosted Glass Aroma Tubes, where they can be used with extra-fine botanicals. For routine cleaning, let the screen cool, remove it and gently brush away loose residue before refitting.
