### ⭐⭐⭐⭐⭐ Water filter
*by M***D on 4 September 2025*

Good filters for the price I noticed in a previous review that the customer had the filter upside down, the arrow on the filter tell you the direction of the flow , so the arrow should be at the top of the filter pointing upwards to indicate the direction of flow . It’s not the end the flow goes into .
