What's difference between filter and nonfilter relay? I know, it's filtered from public, but make any sense to have both relay, or have only one?
Welcome Curated Feeds: https://feeds.nostr.band/
Many people believe Nostr needs some new feeds.
Here is one: wss://feeds.nostr.band/popular - all notes with 10+ interactions.
Or another: wss://feeds.nostr.band/meme - some memes, as you might expect (curated by nostr:npub10awzknjg5r5lajnr53438ndcyjylgqsrnrtq5grs495v42qc6awsj45ys7 ).
Add a feed URL to your relay list. Then, if your app allows that (Damus), you can go to Global, switch off other relays, and enjoy the nice filtered feed.
There are also feeds with pictures, video or audio.
And you know what?
You can create your own curated feed, and let others subscribe to it!
It's built around labels, NIP-32. You add some labels to some notes, and our custom relay will then serve the notes you've curated.

There are many approaches to curation, algorithms and filtering. Hopefully, this new tool could help Nostr become more engaging, welcoming, diverse and safe.
Discussion
When you connect to a relay, you should logically expect you’ll be getting all the notes it broadcasts. So if you already have a connection to a high quality maintained relay, like filter.nostr.wine, you don’t need to connect to a general purpose relay.
Obviously, there are special cases, like curated relays, like the ones Artur mentions in his post above or specialized relays, e.g. the ones operated by your local community, which are not being monitored by the paid filter relay you are using.
