Profanity Filters vs Site Blockers
Published: September 10, 2026 by Andrew Apell
Site blockers remove places while profanity filters remove words, and most households need both. The usual layers look like this:
- Use the operating system’s supervised profile controls for unsafe categories and specific unwanted domains.
- Install PureWord to filter profanity on every approved site.
- Use Excluded URLs to filter everywhere except a few sites or Included URLs to filter only on specific sites, if you want the filter scoped rather than global.
- Enable Parental Lock if the browser is shared with children, so the filter and its settings cannot be changed.
FAQ
Does a profanity filter replace a site blocker?
No. They do different jobs. A filter cannot stop a child reaching an unsafe site and a blocker cannot clean up swearing on the sites you keep.
Can one tool do both?
Some tools bundle both features. With PureWord, the Excluded and Included URL lists give you site-level control over where filtering applies, while the word lists control what is filtered.
Which is better for screen sharing?
A profanity filter, because you can keep using the sites you need while swearing stays off the shared screen.
Which is better for kids?
Both. Block the sites that are unsafe, then filter the profanity on the sites you approve.
Summary
Site blockers and profanity filters are not competitors, they are two layers. Block the sites that should not be visited at all, then filter the words that should not be read on the sites you keep. PureWord handles the word layer on every website, locally and for free.
