Filter is correct size.  Problem is the filter is fragile and the packaging was inadequate to keep it from being crushed around the edges.  It will probably work when I use it.  It was not needed for immediate use.  I ordered ahead so I would have a filter available when the current one needs replacing.  Whether it will work as well as designed with the edges crushed is unknown.
