We just got here in Winnipeg about 3 months ago. We read all labels before choosing for ZeroWater. And WOW!!! We can taste the difference between other water filters and ZeroWater. I drink a LOT of water daily, and this was the best feature for me. Winnipegs water tastes and smells chlorine, and this is the only filter I know that I can get rid of it. 
I got even more scared of how dirty the water is!!! You can check on the photos and see for yourself. 
If you are in doubt between ZeroWater and any other water filters, go for the taste, and check the TDS number of each one. 
Drinking a lot of water we just changed the filter (1 for every 3 months). its worth!
