Product review (5 stars): Good quality replacement filter for Mavea pitchers.
I've been pleasantly surprised with these filters. They take a bit more preparation than the Mavea filters, requiring that they be dunked in water for 15 minutes before use and also that the first 3 pitcher fills be dumped, but afterward they filter quickly and efficiently. I've had the first one installed for a few days, and it does a good job of improving water taste and oder. They certainly work as well as the original Mavea and are a great bargain at nearly half the price.

Update 10-31-17. I'm happy to say that the first filter lasted 4 months before I finally decided it was time to replace it - even thought the water still tasted pretty good. These filters really are great!
