It's a bag of rocks.
Scientifically speaking, everything contains carbon and yes they might attract some impurities to rest on them, but there's literally no biological or mechanical mechanism in place to legitimately make this function as a filter. Your water might taste different, but that's because there's a rock in it changing the Ph values (honestly another unnecessary thing to do, your body self regulates Ph values within a certain range). They're also LYING when they say this is organic. Organic material must be a live organism or come from a live organism. Again THESE ARE JUST ROCKS. If you want to filter your water properly, you need to crush these and stick them in a few layers of other finely ground rocks with a membrane in place to separate finer particles and roughly two other stages of filtration.<br /><br />As for all you people out there trying to get rid of bad vibes... How about you stop buying this junk that people tore into the echo system to obtain? Mining severely impacts the earth. It's not a sustainable practice at all. These rocks are the source of bad vibes because they were removed from the place they belong.
