Security

• Filtering software is also useful for ensuring that children are able to use the Internet safely. There are far too many predators using chat rooms and social media on the Internet for you not to take the precaution of using filtering software. Even if you cannot block all types of chat rooms, most filtering software will have a feature to block particular websites.
  
  

Efficiency

• It is very common for employees and even students to try to use websites that are of a leisure or recreation nature when it is not appropriate to be doing so. This results in a slower work pace and a loss of productivity. Websites that are the usual culprits for such use include social networking, email accounts and any sort of general-informational or fun websites. Without a filter, use of these websites will add many hours of use that is of no productive value to a computer's history.
  
  

Inappropriate Content

• Children are using computers and the Internet more and more these days, both at home and at school. For this reason, it is important to be sure that inappropriate content is not being viewed by children of younger ages. Filtering software can ensure that children are only viewing websites that are appropriate for their age level. By blocking pornography or other websites with adult content, you will be able to worry less about what children are finding on the Internet. Usually, software is able to automatically block such content.
  
  

Accessibility

• The resources of your computer are limited. These resources include RAM and bandwidth, both of which can affect how well and efficiently you are able to use your computer. Filtering software can help you to fight this issue by blocking certain sites that encourage activities like downloading, which take up a lot of bandwidth and a lot of computer storage space. You can also use the filtering software to block sites that stream music or video and use much bandwidth themselves.
  
  

Warning

• It is true that Internet filters can cause issues when they block websites that they are not intended to block. This is because the filters are not, in fact, human and cannot make subtle distinctions between the context in which some topics are discussed on the Web. Filters will instead only block the content that they deem to be inappropriate without consideration of the context. To this end, certain sites with legitimate information, such as medical and biological science websites, are automatically blocked by filter software.
