    Hi, everyone! I'm wondering how long activated carbon lasts once it's been used, not new in the box. In other words, how often do you really need to replace the carbon in your filter? Thanks!

    Every three weeks unless your using it to remove Meds then its as soon as the treatment is over

    Good morning,

    I'm with Don and I change my carbon every 3 weeks. After 3 weeks (maybe 4) the carbon begins to lose its effectiveness.

    No. Washing it or baking it, nothing will reactivate it.
