Product review (2 stars): Not the quality of OEM Mavea Cartridges
You do get what you pay for.  These filters are not up to snuff compared to the OEM Mavea cartridges.  The flow rate through is much higher, not sure of the quality of filtration as a result.  I will be going back to the made in Germany Mavea's, the water spends more time in the filter before coming out.
