((snip)) i gave up on kalittas. Those damn filters are the most annoying pieces of @#?!
^^^ this. Without the "unless". There is no unless. The filters are a horrible, terrible, poorly designed system intended to aggravate specifically me.
Later, I learned, collapsing filter waves are "okay", and whether they remain perfect shape or not, will probably and most likely not impact the results, and therefore, maybe these filters aren't so badly designed. But then, that's like pulling out a fork from a pancake restaurant's dishwasher with a piece of rice still stuck on it.
