CleanBrowsing Family DNS Review – The “Invisible” Internet Filter
CleanBrowsing is the definitive “Zero-Software” solution for families who want to sanitize their entire home network instantly. Unlike apps that must be installed on every single device, CleanBrowsing works at the DNS (Domain Name System) level. By simply changing a few numbers in your router’s settings, you can block pornography, gambling, and malicious sites on every device connected to your Wi-Fi—including Xbox, PlayStation, Smart TVs, and guest phones. It is famous for its Enforced Safe Search capability, which locks Google, Bing, and YouTube into “Safe Mode” so that explicit content cannot be searched for, even if the user tries to turn it off.
VERIFIED DATA: CleanBrowsing is widely respected for its “No-Nonsense” privacy policy. Unlike other free DNS providers that sell your browsing data to advertisers, CleanBrowsing does not track or sell user data. In 2025 latency tests, its Family Filter DNS servers showed excellent response times, often faster than ISP default servers, ensuring that your internet speed remains snappy while being filtered.
Core Filtering and Performance Matrix: Detailed Analysis
CleanBrowsing offers three main filters: Security, Adult, and Family. The Family Filter is the most aggressive, designed specifically to create a safe bubble for children.
| Filtering Metric | CleanBrowsing Rating | Expanded Analysis and Technical Detail |
|---|---|---|
| Pornography Block | The filter blocks access to millions of adult domains at the router level. If a device on your Wi-Fi tries to load an adult site, the connection is refused instantly. This covers browsers, apps, and hidden in-game browsers. | |
| Safe Search | Forced Enforcement | Most unique feature: It intercepts traffic to Google, Bing, and YouTube and forces the “Safe Search” parameter. Even if a smart teen tries to disable Safe Search in Google settings, CleanBrowsing re-enables it automatically. |
| Mixed Content | Reddit & Imgur Blocked | The “Family Filter” is strict. It blocks sites like Reddit and Imgur entirely because they often host mixed (NSFW) content that cannot be easily filtered. Note: The “Adult Filter” tier allows these sites. |
| Evasion Prevention | Anti-Proxy / VPN | Smart kids often use free VPNs or Proxies to bypass filters. CleanBrowsing’s Family Filter actively blocks the domains of known VPNs and Proxies, making it much harder for tech-savvy teens to break out. |
| Cost | Free Forever | The core DNS IP addresses are free to use for anyone. There is a paid plan (approx $60/yr), but it is optional and adds features like custom blocklists, scheduling, and activity logging. |
| Setup Difficulty | Moderate (Router Config) | Requires logging into your router (e.g., 192.168.1.1) and changing the DNS settings. Once done, it applies to the whole house. No app installation is required on child devices. |

CleanBrowsing Architecture: How DNS Filtering Works
Think of DNS as the “Phonebook of the Internet.” When you type “google.com,” your computer asks a DNS server for the IP address. CleanBrowsing replaces your ISP’s phonebook with a “Safe Phonebook.”
1. The “Family Filter” IPs
To use the free Family Filter, you simply configure your device or router to use these specific IP addresses:
Secondary DNS: 185.228.169.168
Any request sent to these IPs for an adult site returns a “Null” response, effectively making the site disappear.
2. No Software to Bypass
Because there is no app on the child’s phone, there is nothing for them to delete.
- Device Agnostic: It works on old Nintendo 3DS consoles, Kindle Fire tablets, Linux laptops, and Smart Fridges—devices that don’t support standard parental control apps.
3. The Paid Dashboard (Optional)
If you upgrade to the paid plan, you get a dashboard.
- Custom Rules: Want to block “TikTok” but allow “Reddit”? The paid plan lets you customize the blocklist. The free plan is “One Size Fits All.”
The paid dashboard (optional) gives you visibility into your network traffic. You can see exactly how many threats were blocked and which devices are the most active.

Detailed Performance Evaluation: Usability & Value
For a free tool, CleanBrowsing is unmatched. It provides enterprise-grade filtering for zero cost.
Feature Validation Summary (2025)
- Latency: Extremely low. CleanBrowsing uses Anycast routing with servers globally, so your internet speed is usually indistinguishable from using Google DNS (8.8.8.8).
- False Positives: Rare, but possible. Because the “Family Filter” blocks “Mixed Content,” legitimate Reddit threads or innocent YouTube comments might be hidden.
- Router Compatibility: Works with 99% of routers (Netgear, ASUS, Linksys, Eero, Google Wifi). Eero and Google Wifi users may need to look for “Custom DNS” in their app settings.
- Mobile Use: For protection outside the house (on 4G/5G), CleanBrowsing offers a free app for Android and iOS that forces the DNS settings on the phone locally.
Pro Tip: If the “Family Filter” is too strict (e.g., you want to read Reddit), try the “Adult Filter” IPs (185.228.168.10). It blocks porn but allows social media and mixed content.
Setup & Critical Configuration Recommendations
To deploy CleanBrowsing effectively:
- Router Method (Best): Log into your router and change the “WAN DNS” settings to the Family Filter IPs. This covers every device in your house instantly.
- Lock the Router: Change your router’s default admin password. If your teen knows the router password, they can revert the DNS settings.
- Mobile App for Data: Install the CleanBrowsing app on your child’s phone. This uses a “Local VPN” profile to enforce the DNS even when they switch to cellular data.
- Flush DNS: After setting it up, you may need to restart your devices or “flush the DNS cache” to see the blocking take effect immediately.

Who is CleanBrowsing Best Suited For?
- Budget-Conscious Families: The free tier is robust and permanent. You effectively get an enterprise-grade porn filter for $0.
- Parents of Gamers: It is one of the only ways to filter content on gaming consoles (Xbox/PS5) and VR headsets (Meta Quest) without complex hacks.
- Tech-Savvy Parents: If you are comfortable logging into a router, this is the cleanest, most lightweight solution available.
- “Set and Forget” Users: Once configured, it just works. No updates to run, no subscriptions to renew.

Who Should Consider an Alternative?
- Users Needing “Time Limits”: DNS cannot count minutes. It cannot stop Fortnite after 1 hour; it can only block it or allow it. For time limits, get Qustodio or Circle.
- Non-Technical Users: If “logging into a router IP” sounds scary, an app-based solution like Bark might be easier to set up.
- Parents wanting Activity Logs (Free): The free DNS does not log history. You won’t know who tried to visit a bad site, only that it was blocked.

Top Family Safety Alternatives
OpenDNS Family Shield
Primary Strength: A similar free DNS service owned by Cisco. It is slightly less aggressive against “Mixed Content” than CleanBrowsing.
Circle Home Plus
Primary Strength: A hardware device that offers “Time Limits” and “Pause Internet” buttons, which DNS alone cannot do.
Bark
Primary Strength: Focuses on monitoring content (text messages, bullying) rather than just blocking websites.

Final Verdict: The Best Free Foundation for Safety
/ 10.0
CleanBrowsing Family DNS is the unsung hero of parental control. It isn’t flashy, it has no mascot, and it doesn’t send you notifications. But it is the single most effective “first line of defense” you can install. By implementing it at the router level, you sanitize the internet for your entire home instantly. While it lacks the time limits and detailed reporting of paid apps, its ability to Force Safe Search and block adult content for free makes it an essential layer of security for any connected home in 2025.
Conclusion
For a free, powerful, and privacy-respecting way to keep adult content out of your home, CleanBrowsing DNS is the industry standard.
