FYI, the replay by kinma13 shows the water filter in both the HW276 & 296. Mine needs to be replaced because when my daughter used it and they filled the fresh water tank with non-potable water. I found out that none of the RV mfr's. do not support that size (5). I may replace mine by using something different (I have several ideas, but not sure which one I will use until spring). you may want to check with Forest River, ask for the Tent Camper parts department (574)642-8927, Kathy Swope, email
