Basic, Good, Better and Best. USA-made, AlkaViva Filters - Differences Explained

All of the filters for our AlkaViva (previously IonWays) water ionizers are made in the USA using only top quality, extensively tested materials. There are lower quality knockoff filters on the market that are made in Asia and do not remove contaminants like our genuine AlkaViva filters do. Using one of these will void your valuable warranty.

All AlkaViva filters offer you our more expensive and effective solid BioStone Carbon Block Technology. Other brand ionizer filters – and the knockoffs – typically contain little more than GAC carbon (carbon in a loose granular form). GAC is effective for removing chlorine but not efficient at removing chloramines or much else. GAC also channels - where gaps are created through the loose carbon reducing the filtering effect. When you buy AlkaViva filters you get superior performance and uncompromising safety. You are investing wisely in your health and the health of your family. Learn the different types of water filters we offer and choose the right one for you today.
