Review: Good filter - Good
Review: Water smells like fish … Had to throw it away - Awful water taste (bad fish) i flushed my whole system like 5 times and every time the smell goes after flushing and comes back after water settles for a few minutes in the filter . I’ve noticed a couple of reviews here mentioning the same issue, it would be great if the vendor can explain what’s happening here and whether its a product defect or something. I had to throw this 3 days after hours and hours of flushing/wasting water

### ⭐ Horrible after taste

This filter gives an horrible after taste, tastes like plastic and not pleasant. Have wanted a few weeks to see if it goes away and run many liters of water through it but no improvement.
