How do you not have the filters for an alkaline machine a few years old I bought my alkaline machine a few years and the filters Cosan USA sent me to replace are not compatible. How do you not offer the same filters for an older machine? I called and no one answers the phone. I sent an email through the website; and via my gmail. I read their return policy and I would be responsible to return the items. Where do I return it to? I am very disappointed.

This Pure Hydration system works great This Pure Hydration system works great. I've been drinking it for about 2 weeks now, and I feel much more energetic since i've been on it. Usually, by the afternoon I would feel very tired and sluggish, but ever since I started drinking this ionized hydrogen infused water, the afternoon's are not a problem, and I get a lot of work done now.

Important change My water now has a good taste & I would recommend this company to anyone who wants Alkaline water. I am reading a book called the PH diet & it says if you can only change one thing right now It would be to drink Alkaline water since it is so important for you.

Cosan is simple to install, takes very little space very user friendly. For the price I would reccomend if your tap water isn’t too hard.
