You made me go look at my directions, and mine say to use the same. The hardest issue I had with it was making sure the filters are facing the right direction when you insert between the plates. Got it wrong the first time and it is like the filters were not working and drip tray was catching it all. So I stopped and read directions again. But it is a joy to use, plus I have an inline house filter I have hooked up with my All-in-One vacuum system when I need it. Handy for sure.
