https://berkeywaterfilter.us/berkey-fluoride-filter/ If you care about you and your family's health you will not want to drink tap water, and always have a filter strong enough to get out pathogens like viruses, bacteria, amoeba and heavy metals like fluoride, mercury, lead and radiation. Most city water is contaminated by Sodium Fluoride, which is a neurotoxin (brain and nervous system poison), immune system poison and can lower your IQ by 10 points. Here's how to get it out of you and your family's drinking water! Berkey Water filters for portable use and Pure Effect with Zeolites for whole house water filters (or drinking water filters) are the absolute best! #fluoride #waterpurification #filter #water #health
