I bought one for my DD vacuum cleaner and first noticed that after installing this filter the cover hardly fitted again. so tight that they are a) difficult to "escape" if you lazily toss the contents of your vacuum upside down in the bin, and b) the snug fit can also help ensure they are snug while you're actually vacuuming so use in there. I'm very happy with mine and plan on buying another one later. In fact, my only criticism is that the seller immediately started selling them in pairs at much better prices (almost cheaper!) right after I bought mine. It happens, but I like this filter.
