I used to do one 50% a week on my 3 gals. and the bettas lived quite some time. BUT - I now do two 50% cleanings on all my 5 gals. & under. I really think the fish do better with the two cleanings a week - but that's just me.
And, yes, they are all filtered. :)
On an unfiltered - one 50% & one 100% a week is my understanding.
