This article is about the filters that we develop and that come pre-installed in AdGuard. To check them out, you can download the AdGuard app

This article is about the filters we create to use in AdGuard and other ad-blocking software (e.g., uBlock Origin). Filters are sets of rules in text format used by AdGuard apps and programs to filter out advertising and privacy-threatening content such as banners, popups, or trackers. Filters contain lists of rules based on their purpose. Language filters include rules for corresponding language segments of the Internet (e.g., German filter). Task-based filters group rules that fulfil a specific task, such as Social media filter or Tracking Protection filter. Enabling or disabling a filter makes it easier to work with the entire list of rules at once.

Our filter policy defines what AdGuard filters should and shouldn't block, as well as the rules for adding and removing rules from filters. Read the full text of AdGuard filter policy for detailed information.
