I made this to hold my Brita water filter on the countertop of my camper. Whether its full or empty, this will hold your water filter pitcher upright and will not let it fall over no matter how bumpy the roads are. Tested over a 8000 mile drive across 15 states.
I recommend some double-sided sticky tape to keep it in place on your countertop.
