Ask HN: Tips for filtering HN RSS feed

Hey guys, so I've been reading HN for around 10 years.

And over the course of time it changed a lot, so now I see more and more things that do not fall under my own criteria of what HN used to be or rather how I want it to look.

In other words, I would call it casual news that I stumble upon when I read non-tech news sources.

  My question is: how do you filter HN feed so that you don't see things that aren't tech related like housing crisis, talking to whales, healthcare news et cetera?
