A filter may refer to any of the following:

  1. The most common filter is a software filter that reads data and manipulates the data to fit another output pattern or removes data that may not be needed. For example, spam filters help filter unwanted e-mails from reaching your Inbox.

  2. Hardware devices can also be filters. For example, a firewall can filter network traffic to help protect a network.

  3. The term filter also refers to a device inside a power supply that smooths out pulsing DC (direct current).

  4. With Adobe Photoshop, a filter is a digital effect used to modify images. See our Photoshop filters page for a complete listing of Photoshop filters.

  5. Alternatively called censorware, a swear filter, or a content filter, a filter can describe software or hardware which selectively blocks specific data. For example, a parental control Internet filter can block obscene websites from children on the Internet.
