I bought a whole house filtration system for chlorine and other chemicals plus 2 whole house filtration systems for fluoride because I am extremely hypersensitive to both chlorine and fluoride and did need 2 fluoride systems to get levels down low enough I did not react. Anyone hypersensitive can not handle above .07ppm (they add .7ppm of fluoride to water on top of whatever the naturally occuring level of calcium fluoride is already in it). I had lived in the country and had spring water and was nervous when we moved to town that we would not be able to get enough chlorine and fluoride out for me to be able to use the water, but I am very excited to say that I can use it just fine!!
I have recommended this company and their filters to many people, some of who I know have purchased them and are happy as well.
Highly recommend this company. Their customer service is great and they are always helpful with questions and very knowledgeable.
