I’ve tried quite a few filtered pitchers and have been regularly disappointed both in taste and measurements of dissolved solids (I like to see a reading of 5 parts per million or less).
The ZeroWater ZP-010 was the first that I actually liked.
The water tests at 0 to 1 PPM and thus tastes extremely clean, and the filter lasts a solid 3 months or so at 1 to 1.5 gallons per day being run through it.
It also comes with a TDS (total dissolved solids) meter so you can easily see when it’s time to change the filter.
Forget Brita and Pur–go with ZeroWater.
