Two things. 1) I almost didn't buy because someone wrote a review saying they didn't get a real rainbow filter, but figured I'd just return it if I didn't get it - I DID get a genuine part. It is rinsed with water and there are no soapy images on it. Glad I took the risk. 2) I was concerned because the photos on the internet made it look like the exposed vent was round and not oval like the part I wanted, so I figured it might not fit. Well, it's oval, not round. Funny because I posted a photo with my review and it looks round in my picture too. To illustrate this, I placed a round lotion container in the hole. Hope this information can help someone because I was really hesitant.
