Many people ahve tap filters or pitchers with filters so that they can eliminate bottled water. BUt what happens to the filter? I didn't know what could be done but I felt terrible tossing it out. I also wondered if the red light was telling the truth but I can't figure that out. I did find a way to refill the disposable filters on Instructables.
Instructables is a site that has how to's for almost anything. It is really interesting and I love the ingenuity and determination displayed by all the contributors. This is what the Internet was meant for; sharing useful information!!!!
