Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
Please share some sample filtered URLs so we can check and advise accordingly.
Meanwhile, Rank Math usually sets the canonical URLs to the main URL for those pages with query parameters (filters).
This way, search engines would refer to the original content, and avoid duplicate content issues.
Looking forward to helping you.
