my original pet 60 filter looked just this one. notice 4 corners and two taps between a set.
not all the filters have this.
that spot is THINNER, and lines up with the release bottom for the main canister.
Just look at your original one, and match. can't say the other models are like this. But use the wrong filter, and the button is hard to press.
might break like mine did.
