There is currently no way to refill or recycle Brita filter cartridges in North America.  Take Back the Filter, a grassroots movement, is advocating that Brita (i.e. Clorox) offer recycling for old filters so they don’t stock pile in the dumps.

Inspired by Jim McKenna’s and John Lieberman’s successful campaign to urge AOL to quit sending out unsolicited CDs, they are collecting used Brita filters, both pitcher and tap, to deliver to Clorox en masse at some point in the future.

Filters in the US can be mailed to the following address:

Take Back The Filter
5245 College Avenue, Box #815
Oakland, CA 94618
