    Taste good water. Easy to install. Very convenient to not need to add fluoride attachment underneath like other brands’ filters.

  2. Megan Lamon (verified owner)

    I use these in place of my Berkey filters and they work great. No complaints and the company is responsive and helpful.

  3. Stephanie Mullenmeister (verified owner)

    After years of heavy lifting of water bottles, I am happy to have replaced my water need with this filter system. Have been using it for years and love it.

  4. Sharon Bruyere (verified owner)

    Customer service was excellent when I was not sure which one to buy for my Berkey system. Quick and explained and even left a coupon code for purchase. Super happy with this company and so far with the quality of water!

  5. CHRIS WEIGAND (verified owner)

    I`ve been using these since they were Pro-Pur, maybe 15 years. Excellent. And the customer service was great when one I received was leaking. They sent me a replacement with no problems. I started using them because the filters like Brita have a chemical for keeping bacteria/fungus down. These apparently have silver.

  6. Andrea Lee (verified owner)

    I’ve used other water filters and these are the best. The water tastes amazing!
