Question: does this filter flouride
Document: I was disappointed that I was not allowed to return this item. I was not aware there was a filter in this waterbottle and I wanted one I could put ice in. What a waste of $40!
This bottle fell from a hook to the floor while empty. As a result the filter broke at the top making it useless as a result of the filter at the bottom a long stem. Bummer! Don't let this product fall!
After purchasing this bottle to make it easier to drink filtered water throughout the day, I started to drink less and less water since it was so difficult to drink out of. I read the reviews that said you have to work a bit at it to suck the water through the filter and after I first got it, I agreed.
I own two of their first generation stainless steel water bottle models and I am very pleased with them. The water tastes crisp and clean without the awful chlorine taste. Their customer service is very professional and this company definitely stands behind its product (I had to return a filter once and did not return the second one since I already installed it in the bottler.
I bought one for myself and one for my husband thinking it would be great to use particularly at our work where the water isn't the cleanest. But it takes a lot of effort to get the water up through the straw every time, a lot. This product might make more sense for a hiker. I'd rather pour water through a filter and drink it easily, than have to suck it through a filter every time I'm thirsty. I still use it occasionally, but my husband refuses to use his now.
Very disappointed...
This will be the last water bottle you will ever need in my opinion. I can't say enough good stuff about it.
That is why I bought two, one to drink and the other one to chill in the fridge.
Plus leaks when on its side...overpriced.....hard to drink out of its straw...I would not buy this again....I would get a refund if I could,but I bought it about 2 yrs ago.
Although the price is a bit steep, you will receive a great quality, American made product. I would pay extra for that any day of the week. Yes, it feels a bit different to drink out of these bottles but you will get used to it. They are great for the gym, the car, work, school, hiking, biking, etc.
