Yes, 1Blocker Premium can import filter lists from third-party providers as an alternative to our default filters. This works per block category: Ads, Privacy, Annoyances, and Adult Content can each use either 1Blocker's default filters or external ones, whichever you prefer.
To switch a category, open it in the app, tap the (...) button in the top-right corner, and choose External Filters.
For the full setup guide and requirements, see External Filters.
On a side note, we do our best to deliver well-balanced and optimized filters tailored for the Safari content-blocking engine. So, we recommend sticking to 1Blocker's default filters whenever possible. Preparing them for 1Blocker involves thorough testing to ensure the rules integrate smoothly and work effectively within our app without affecting its performance.
You are also always welcome to share your thoughts and ideas on how we can improve our filters further.
