This filter filters much better than the original equipment. This is a thinner thickness. It fits so snugly in the plastic filter holder that it takes some effort to attach. I take it off and wash it after vacuuming it a few times, it washes easily. Soap is washed out much easier than a native filter. I note that the 2nd filter that fits under the plastic filter holder is also included. This filter does not get dirty because the filter above does a great job of filtering.
