5" I've never bought a Wynn filter, but don not think it comes with a flapper to clean the filter.

Hi Fred, No a flapper will not be found on a Wynn filter because that is not a recommended way to clean any of the high end filters (according to the filter manufacturers) it lessens the life of the filter by breaking down the "fabric." Wynn and Donalson (Torit) both told me to only use compressed air, from about a foot away, on the outside of the filter, blowing into the inner core.
