Why do you need any kind of filter pad in your overflow? Is it to
keep the drain silent, or to keep the water level at a certain height?

I used to run my HOB overflow with only a 90 degree elbow and some
rigid airline tubing. It worked well and kept things silent.

It's there to serve as a prefilter. I could probably get by without it.
