Replaced my 3 stage pre filters. It's important to do this. If the flow rate slows down unexpectedly it could be time to replace the filters. If you really want the purest, cleanest, healthiest, highest Antioxidant, highest alkalinity water you need to get the appropriate pre filters based off of a water report for your water supply and hook them up to your water line before the water gets to your kangen machine. This ladies and gentlemen creates what we call "glacial milk." It keeps the beneficial minerals in (unlike reverse osmosis, purified, & distilled water) and takes ALL the bad stuff out (yes, even fluoride!) unlike your Brita or your Pur filters! You would be blown away at how good this water tastes and feels. ❤️💦👏🏻 #prefilters #waterfilters #ionfaucet #glacialmilk #kangenwater #alkalinewater #antioxidantwater #purewater #cleanwater #filteredwater https://www.instagram.com/p/B1mEGm9n1FQ/?igshid=1mnwjqdndnrsy
