Filter replacement is easy. CAUTION. When removing the wand that is immediately above this filter you must reach around the back base and feel for a tab sticking out. Pull on it and lift the wand up. If not you may break the tab off which is a retainer needed for the center wand that supplies water to the upper rack. This would have been a 15 minute job but I broke the tab off I mentioned earlier. I ended up adding a stainless steel screw through the base just above a flange that rises when the water pressure forces it up.
