This filter does not work. The foam was too big for the Shark Rocket filter system. The foam filter and top filter looked like they would fit in the filter box. However, the Shark missile failed to maintain suction power, leaving the vacuum unable to suck up virtually anything. I bought another filter from another company at Revain and had no problems. I have to say that this purchase was wasted because the product does not work as advertised. And yes, I have checked that the Shark Rocket I own is listed as a match on this replacement filter.
