This is one of the more frequent questions asked about these products. There is absolutely no taste to the liquid that these units produce. To some, the taste that comes from the tap is often very distinct, and it will leave a bad taste in your mouth. With these products, the line of activated charcoal eliminates the chemicals that have a bad smell and leave a foul taste in your mouth, and the split molecules actually feel lighter and smoother in your mouth. Plus, if you have ever guzzled a big glass down after a good workout and could feel a distinct sloshing feeling in your stomach- these devices actually help to reduce that feeling. Due to the fact that, as we stated earlier, the molecules are split and reduced in size, they actually absorb much faster in your system.
