We have been using Zero Water Filters for the past 3-4 years now, because they have and continue to prove that it's the cleanest filtered water that we have had yet, at a decent price!  Since using Zero Water Filters, we haven't had any negative health problems due to drinking the water after it has been filtered through a Zero Water Filter, and in fact, have been drinking A LOT MORE water since using Zero Water Filters, and boosting our physical and mental health in getting through a better successful day!  We have been so impressed, that we have bought Zero Water Dispensers with Replacement Filters for friends and family, as gifts, and after they have tried it, enjoy the same benefits we have and so been happy to convert them to enjoy the same trust in Zero Water Filters, that we enjoy everyday!
