I have a very old Eureka vacuum cleaner that uses bags. I don't have the model number but the front has the following words: "ALT Air CLEAN" and "DELUXE."  I thought I had more bags for it, so I threw out the old one, but now I found I don't have any bags left.  Does anyone have an idea of the bag I need? I thought I saw a Y on the old bag.  I also saw one online that looked like it would fit that was an "F & G" bag. Help!!!! Thank you...:)
