I have been using aragonite filters for three years now, after extensive research on filters and their different technologies. It is indeed very good in many aspects. Through the aragonite, a substance derived from pearls, it converts hard salts into salts that can be fully absorbed by the body. So, for example, it helps with bone health and prevents the formation of kidney stones. Maybe it is insignificant compared to the advantages, but I want to be honest the taste can be slightly bitter once the filter is newly replaced but I think this applies for all filters and after a couple of months it tastes great again. Overall, I highly recommend it, especially compared to common carbon filters. Especially for individuals with health issues in the gastrointestinal and urinary systems, I believe it makes a difference

One of the best filters. I bought it 3 years ago after a lot of research because it cuts a lot of impurities and salts. EXCELLENT. It's worth its money, even if it's not advertised on TV.
