<span style="font-family: 'arial black', 'avant garde'; font-size: large;">Hello! I just recently got a Fantom Thunder and I know how to remove the filter casing I think. I hold that one button thing and pull up. Is that right? It is STUCK in place. Wont budge a bit. I need some more advice or tips for getting the casing off. The picture down below is the unit </span>
