It appears that this model 2300 is being phased out. Amazon does not mention this. Amazon calls it a special for Prime members. You cannot get the replacement filter, bissell part number 1611508 or 1611500, from Bissell, Amazon, or in Google search. Bissell and Amazon claim the filter is washable and does not need to be replaced. But the filter is too fragile to be washed more than a couple of times. If the stuff in your dirt cup is mostly very fine carpet fibers or other light- weight dust, it sticks to the dirt cup and filter and flies all over when you try to empty the cup. I would return it except that I found all this out by using it and so it's too late to return.
