It looks like it only has one filter and it's 25 micron, so it won't actually separate the trich heads, which are about 4 times that size, from the plant material. It would catch almost everything and only mold spores would go through. You would need to buy another filter probably about 120 to 180 micron to put before that 25 micron one. When you buy these kits you need to find ones that come with several filters, not just one. You can actually buy nylon filters of 150 micron size for brewing so you don't actually need to buy actual bubble hash bags though maybe they would fit better inside the outer bag you already ordered. Maybe bubble bags are really just brewing bags relabeled, wouldn't surprise me.
