We have had several water filtration systems and Pure water taste the best - we are happy we found yours when we were looking to remove radiation, which is local to our area. The sales person was friendly, well informed and knowledgeable about water filtration and very helpful in answering all our questions. He helped us to find the right one for our water impurities. Thanks for being the only company who makes this type of product. Reverse osmosis or distillation to get rid of radiation were not acceptable to us. Thanks for your help, product and good water.
