I have used mine for the past year almost every day. It is best for coffee, tea, and ice cubes because the water is so clean that it has no taste. Mixed with a small amount of juice it makes a perfect summer water. I also use the zero water in my Nespresso machine as it tastes great and it leaves next to no scale to clean away.
Not only would I recommend to friend but I have told all my friends they must buy one!!!! I did my research on clean water filtered pitchers and couldn't be happier with my purchase. The 10 cup is perfect, I'm the only one using it so the filter last forever, I'm constantly filling bottles so I have it on the go, I drink 60 oz's of water daily. When it says "zero" that's exactly what it means, I tested my water, my works water,my sisters water and "yuck" " what have I been drinking!!!" The first thing I did was use the supplied tester and sure enough it read "zero". So bottom line, if your looking for the cleanest water, stop looking, and buy this one!!!!
Our vet suggested we purchase this as it's best for cats to drink filtered water. He and his wife purchased a Zero Water pitcher and filters and although he doesn't make from recommending this product he tells his clients about it! The proof is in the pudding as our cat loves this water and drinks more than before. I use it to make coffee and tea which definitely is better than using tap water. With all this being said, I need to contact customer service as the TDS does not function al all...just got a defective one and I know that happens at times.
