Replaced the HEPA filter in our Rainbow e2 with this one so far so good. It has been sealed and boxed and looks like a real rainbow piece. Apparently you have to replace the HEPA filter on these vacuums every few years and after trying to clean the old filter and not seeing much improvement I ordered it. Since we have a lot of kids and pets in our house, the new filter made the Rainbow smell brand new when I cleaned it again. Hooray!
