Glad I took the plunge

YouTube now has lots of contradicting opinions of the best gravity filter. Sadly, I initially ordered an inferior brand, but eventually got all Berkey

We LOVE our Berkey water filter so much that I bought each of my daughter’s family one. I can’t believe how great the water taste especially when compared to the horrible water that comes out of the faucets in our home!

I have been supplying the family with Berkey filtered water for years. Started with the small size and advanced to a "Big Berkey". I find I can not drink water when away from home because I NOW know what "clean" water tastes and smells like. I notice a very real difference. I will continue to use the Berkey system as it is easy to maintain, makes water "drinkable", and provides peace of mind.

The Berkey Big Berkey, 2 filters and 2 arsenic filters

I love my Berkey water system. There was a couple week delay getting the products but TheBerkey customer service was very quick to respond to my inquiry and my product arrived in great condition. I would recommend this company. I was confused because of so many places where you can buy this product. I am happy with my choice.

Review of my whole Berkey system

We have just been through Helene - The Berkey is invaluable. We were able to purify our water, rainwater and now our city water,for ourselves and to share with neighbors for drinking and for washing produce and cooking... . It has saved us. Thank you so much - This was and is one of the most valuable tools in our home.

Trusted Brand

Fakes on non approved websites but know I can rely on this site. With EPA the organization to control the health of our teeth, can’t be trust them. The required PPM in water is high for our children & grands. If you are mixing your own formula, include these filters in your Berkey!

At first I was very suspicious bc I ordered from theberkey and I didn't hear much from them. Nowadays we get everything so fast and with plenty of tracking info. I called and said I was suspicious of a scam. Well I finally received it... actually I gifted it to a special brother who moved to a town with city water and I love him so much that I want him to have pure water. My brother loves the Berkey and is forever grateful to me for caring about him. He is on a new healthy living kick... cut out alcohol, soda, juices ... just drinks water and coffee/tea...and now he exercises every day. He is like a new man and very happy. When other family visits him they learned about his Berkey and were impressed ... now they all want a Berkey! Sorry, I can't gift everyone ... and they have to buy their own 😔...
