We are currently out of stock on replacement alkaline water filters for our 108 and 109 pitchers. We are in production and estimate that we will be back in stock within 35-40 days.
We sincerely apologize for this inconvenience. We do have a supply of new but unboxed green 1089 water filter cartridges (some may have open foil to double check color). This have the same internal design as our production units but they are unboxed and are part of the batch we had produced to ensure that the filters were functioning properly. These will fit any model 108 or 109 pitcher that you have.
