Filters come in various forms, search history, language, location, OS, account-based history, etc.
Filtering my results based on my location is still a filter bubble. Filtering it based on anything, and not just showing me exactly the same results as everyone else who searched the same query is the definition of a filter bubble.
People who don't want to be bubbled use DDG. It's a big part of the reason it exists, and you want that changed. What you actually want is another search engine, which is probably Google since they have the most functional (in the sense of utility derived by the end user) filter bubbles.
