We have 2 old vacuum cleaners (both at least 10 years old) so I have no idea what models they are (and if they even make them!) and I had no idea what filters I got clean should change! I was using one about a month ago when I emptied it and decided to undo the area the filter is in - oh my! Dust has accumulated over 10 years. Although I cleaned it, I figured that maybe it would work a little better if I bought a new filter (more suction, longer, etc.). So glad I found her here! Who knows if they will help, but we don't have to buy new vacuums when a filter change will do. good price too.
