Bought G5RO Global Water for work and it's amazing. Cold and hot water is all we need (we currently have an office of 15 staff). I like the machine, but the filters for it are not standard. They're well built, but unlike most reverse osmosis systems, you're tied to the filters you buy and they're quite expensive. Don't get me wrong, they work great. The spring valve prevents most water leaks when changing and is so easy I can get anyone in the office to do it. I'm getting about 13ppm from a source water with more than 200ppm (this is not a reverse osmosis filter, just three pre-filters). It's worth it for everyone to have clean water at work. I just want to know beforehand that I'm buying a proprietary system. I'll probably need a few more to have a supply for a few years in case they stop making them.
