Will there be an option to work with filters without ajax?
It would be nice to make a separate option, when enabled, parameters from the selected filters will be dynamically added to the shared URL.
It is also better to make these parameters configurable so that in the URL, instead of technical information about the request, you can see simple and understandable SEO parameters. This will make it easier to read information from the URL, as well as have a permanent link to the filtered page.
For SEO, of course, you will need more settings there, but you can start by adding parameters to the URL.
