The confusion is completely understandable as we have paper filters with both brown and white rims.  They are identical otherwise (just made with different manufacturing equipment).  The old "Legacy PLA" filters have a UPC code on the brown rim.  So they can be easily distinguished.  See the image below.  The Legacy PLA filter is on the bottom.  



HISTORY:
The EcoPour filters were originally manufactured using PLA, a compostable bioplastic.  Those are the "Legacy" filters.  We figured out how to manufacture the Ecopours with an all-paper filter design and started offering those last year.  The All Paper format was important to us to address concerns of the bioplastic in the water path and as part of a continued effort to be as eco-friendly as possible (faster biodegradation).  The All Paper EcoPour will remain the focus of the company moving forward.  But, we still offer the legacy filters for the time being.
