Refill Disposable Water Filters With Activated Charcoal

Contrary to popular belief, water filters don't actually run on magic and disposable plastic. However, they're very easy to change out, and you can do it for much less than the sticker price that comes with the Brita name.

Instructables user IAMSatisfied shows in the video above how to cut open a single water filter (the only one you'll need to purchase) and refill it with fresh activated carbon. The key ingredient that actually does most of the filtering is extremely cheap, and the disposable filter can be modified for repeated refills, potentially saving a fortune over the long term.
