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.

,,,,paid 5 hundred dollars for Cosan… ,,,,paid 5 hundred dollars for Cosan USA in 2018...now can't get 4 filters package for replacement....it looks like we lost money...... what a terrible company!!! .... very regret that bought this Hydration system.... in 1.5 yrs we must throw it in garbage.

RO unit to Pure Hydration ??? I bought my Pure Hydration System last October 2018. The connection set-up was from a Culligan RO system. I followed the installation procedure from the Cosan YouTube video. Bought a couple of reducers to connect to my existing RO unit. My whole family was drinking from this set-up since it was first installed until last Saturday(March 9); my wife asked me to check the PH value and found out to be only 7. Checked the water coming from the faucet and it’s higher than 7. Is the RO unit affecting the filters of the Pure Hydration? I’m confused. Need your help.

Great products, awesome customer service, works as advertised! Great products, awesome customer service! I have highly recommended CosanUSA's Pure Hydration and filtered bottle water container to my family and friends. The Pure Hydration is very easy to set up and works exactly as advertised. The water container is perfect to have when on-the-go. I even filter bottled water from the store just to have my drinking water at it's purest ph levels. (Most bottled waters I've tested were very low in ph levels) Customer service is easy to get in touch with and inquires were always professionally handled. These products are absolutely a great investment in keeping your body healthy! Check out their youtube comparison video: CosanComparison1

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.
