I bought this Hepa EF-9 filter to replace the original filter in our Kenmore model 116.31140311. Reviews for cheaper filters said they sometimes don't fit, so I went with this one and the one linked on the Sears website. The way Sears is going they may not be available next time so I may be forced to buy cheaper ones which may or may not fit properly. This filter fits, but requires a lot of pressure to fix it.
