Range Filter Missing Form Label

According to the WAVE accessibility checker, the range filter in a website I manage needs a form label. It would be nice to have a label field for filter elements, with the option to use heading tags or a p tag for the label. Or maybe have a nestable form field element that provides label options? Then any fields related to a form could be built inside that?

Anyone have any thoughts?

Or maybe just provide an aria-labelledby field in the filter elements for easier access.
