Perfect replacements for the G30
I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.
