Goodbye Flouride

I never understood the late 60’s push to incorporate flouride, a poison, in our water supply. Since most toothpastes incorporate flouride in their products, any supposed benefit for retarding tooth decay is already covered. Due to my purchase of a Berkeley I am proud to say that my granddaughter has had a 2 1/2 year life that has been flouride free.

Great Water

I have been using the Berkey for over 20 years. It produces clear clean water that is superior to most bottled waters. I will never give up my Berkey.

Healthy water at last

After many years of using Brita and various fridge filters and believing this was sufficient, I have now learned this is not the case. We all need to watch out for fluoride levels in our bodies. I now have peace of mind knowing that my family will have healthy drinking water in any unknown situation as well. Thank you and God bless!

Simple to install forgot water has no taste! I feel confident and very pleased with the filters.

Sharlene Beale (Orchard Park, US)
clear water

Filter(s) make tap water 100% better. Never had a clearer good tasting water. Encourages you to drink more.

Polly Conner (Granbury, US)

I highly recommend the fluoride & arsenic filter. I’m trying my best to help our health stay well & good. These filters help me do that!!

Erin McClanahan (Lake Worth, US)
Everyone says I have the best tasting water

Not only does my water taste like.... well, nothing (as it should) but the piece of mind I have knowing my kids are drinking pure clean water is priceless.

Mark Miles (Bullard, US)
No more flouride

We know fluoride is not good for your body as promoted by our own government. Taking impurities out of our drinking water is necessary for better health and sense of well being. I would advise anyone out there get yourself a Berkey and spring for the extra flouride/arsenic filters. What you get in your home is not safe.
