    Very Happy

    Posted by Darlene on May 9th 2022

    I used to purchase my filters from Berkey and moving forward I will be purchasing ProOne filters. My water tastes significantly better compared to using the Berkey black and flouride filters. I started to doubt the effectiveness of the Berkey filters because of their refusal to have them certified. I am very happy that this filter also removes flouride. I didn't like that the Berkey flouride filter would sit in the clean drinking water. Periodically the flouride filter from Berkey would feel a little slimy. It did take a little over 2 weeks to receive my filters. I did reach out to their customer service inquiring about my order and they did respond within 24 hours regarding the delay in shipping.

    What an amazing filter that we have used in our Biotechnology Lab for the last four years. This companies design for water filtration outcompetes other brands. Our lab has tested the water samples after being filtered through the 7" filter with great results. Thanks so much for a great company !

    We love these filters! We replaced our old Berkey filters with these. They work well with our old Berkey system
