Review on Certified Performance Replacement Materials: Enhancing Compatibility for Optimal Results by Stephanie Davis

We use our Kangen SD501 EVERY DAY! I fill liter jugs to take to work. We rinse/soak our products in highly alkaline water. We use it to wash floors. Do you understand. We use it A LOT! I'll update if anything goes wrong with ours, but 1-2 months is generally good :) UPDATE: Only a year old and as expected it's time for a replacement. Now small white "chips" appear in the water. So far I am completely satisfied with this filter. I'm about to buy another one.
