This review is to help people figure out where this filter belongs. Thought I'd replace the yellow foam filter on top (I have a Bissell Cleanview 5959A). This is for another filter. I am attaching a photo where I open the compartment where this filter is located. Pulls forward. Push the old filter down and it will fall through the floor. Insert the new filter from below. Voila! Now I need to find and order the yellow foam filter I was planning to buy.
