Well, if the have the DI cartridge on it, you can’t drink the water, it’s unsafe. The DIT cartridge removes any sediment from the water, making it even cleaner.I was looking at something similar earlier on in the day, though granted it was nowhere near as complex as the one you sent, it was only one phase of filtering. I've found quite a few, some look fancier than others but I'll do research on which one to get. some are as low as 40 yet others are around 600-700, so I'll need to know what I'm looking into. I guess something like this will make the water quality better for drinking too, which would be nice, I like drinking water.
I only use this for my saltwater tank, and it provides clean water for my fish and coral.
