Adult and Child Safely Browsing the Internet

There are a number of free DNS-based Internet Filters available for you to choose from that you can use to protect yourself and others online. Looking at them on the surface (by name only), it is hard to know which one is the best, most comprehensive internet filter.

Comparing the Best Free Internet Filters

We’ve compared the Best Free DNS-based website filters by testing them against nearly 10,000 pornographic/adult domains to see which ones are the best at blocking objectionable content. Because the results varied significantly, you might be shocked at the results, as some of them do very poorly in comparison to others. But first, before we get into the results, let’s talk a little bit about why these types of filters are good for you to use.

Why Everyone Needs an Internet Filter

If you have children or ever have children in your home – you need an Internet filter. Early exposure to porn can change the brain in ways that are hard to overcome, leading to a lifetime of struggle with addiction, sexual identity that can ruin relationships, cause isolation and like any additiction, generally ruin your life.

If you are an adult or live with adults – you need an Internet filter. Pornography addiction robs you of life and ruins relationships. Instead, choose to block that junk from your home and your life!

The advantage of Internet Filters that are DNS-based

To begin with, the main advantage of DNS-based Internet Filters is that they protect all the devices on your network (including Chromebook, iPhone, Android, Mac, Windows, PC, or Linux). They do this through setup as an internet filter for your router, and not something that is installed on individual devices. Because of their central setup on your router, they are superior to internet filtering software. They can be used on individual machines as well, but they are primarily designed to be used across your entire network!

Additionally, there are other side benefits from using these filters:

  • First, they can force SafeSearch on sites like Google, YouTube and Bing, stopping adult and objectionable content from being part of search results.
  • Secondly, they can improve your Internet browsing speed by providing faster responses than your ISPs DNS servers.
  • Thirdly, these DNS-based internet filters will also protect you from malicious websites that can install viruses or scam you in various ways.

Everyone should have an Internet Filter that is DNS-based

Because DNS-based website filters protect your entire network from bad websites, every home should have a Internet Filter that is DNS-based as part of their plan to protect themselves and their families against dangerous adult content like: pornography, drugs, phishing sites, inappropriate ads, viruses and other dangerous websites.

You should still still choose to use other parental control techniques as a an additional layer because as you will find out looking at the results below, these filters are not perfect.

Adding to Your Website Blocking Protection – Beyond DNS Internet Filters

In addition to setting up a DNS-based Internet Website Filter, you should also do the following:

For Younger Children

  • Use a locked-down device with a tool like Infilter to create a custom Internet for your child. Infilter only allows them to visit the websites that you allow them to. A “whitelist” approach such as this is much safer than relying on a “blacklist” approach, especially for younger children.

For Older Children

  • Use a online activity monitor like Covenant Eyes or Accountable2You in addition to DNS-based Internet Filtering
  • Have open communication about online activities

For All Children & Household members

  • Have a rule in your house that device use is in a public area. Screens facing out so that everyone is held accountable for what they are doing online
  • Know the passwords and account information for everyone in your family so you can check up on their online activities.
