ProOne G-Series 7" Gravity Filter Replacement - Microplastics, Lead & PFAS

I love these, they have such a long life (a year I do believe) I use them in my Berkey since the Berkey filters were outlawed by the gov. I think these are pretty good, I don’t know chemical for chemical how they compare to the Berkey, but they fit just fine and I like the rubber gaskets more. Plus they send extra, which the Berkey never did 🙃

UPDATE 04/01/2025 - Supervisor Josh reached out and finally provided full refund via PayPal on 03/28/2025. Overall, a very disappointing experience but I’m glad I got my money back. I ordered G3 7" filters directly from the company's website, followed installation instructions, and water did not flow through more than a few drops. LITERALLY a few drops. Contacted customer support for assistance (spoke with Tyler) who recommended to try the installation instructions again using warm water. Tried again with same result. Called customer support several times only to have the automated message loop to the beginning without ever connecting to a customer service representative. After attempting phone contact numerous times, I finally reconnected with Tyler who informed me that filters were indeed defective and a refund would be issued, as receiving a replacement would likely net the same results. No refund received after several weeks, and made numerous attempts to contact customer support, to include numerous emails outlining the issue as well as using the customer support form on the website. Never received a response from any method I used. Sent a total of 11 emails and 4 customer support requests via the website and still no response. Contacted customer support via phone on 2 occasions afterward and spoke with Genie who informed me the refund would occur in 3 to 5 business days. Even received an email saying the refund had occurred, even though nothing was received back to the card I used for the purchase. Called again and Genie informed me that I was to receive store credit for another ProOne product from the web store, which I have no use for. I asked for her supervisor and she stated his name was 'Josh' and she attempted to patch me through to him but I only got his voice mail. Left a detailed message along with my order number and contact info and did not receive a response. Resent one of my emails requesting status of my refund and still no response. Called again today and left a message again for the supervisor (Josh Eskins?). Incredibly frustrated with the lack of customer support and the fact that I paid $102 for defective products that I can't use without getting a response or refund. Very dissappointed with ProOne considering I enjoyed using their products until this experience. Hopefully you won't have to go through the same experience.

was good. am changing to r.o. system .. pro one company is no more

I have been using these for about 3 years now for well water. They are great.i do prefilter the watrr 1st through a votton ball filter system to extend filter life.90 % of the liquid i dring passes through this filter.the water has a nice crispness to it.it will do about 3 gal over night easily. Pushed 1 time to see over 24 hour period constantly filler filter box.was very surprised.just over 6 gal would have been prob 8 if i would have topped filter box off all night.a fella has to sleep

This is the third ProOne filter I have purchased and overall I am pleased. First two lasted a good number of months, but most recent one failed after just a little more than one month of use Since this was over 30 days from purchase, it was not returnable to Amazon. So, I reached out to ProOne several times for warranty replacement and nearly 2 months later I finally received a response and replacement filter. While I would have appreciated a more timely response, I appreciate that they finally provided me with a replacement filter. I think the product itself merits a solid 4 to 4 1/2 star, but the fact that I had to reach out several times, that my initial contacts went unanswered, and the ensuing time delays are the reason for my assigning 3 stars. Nevertheless, my faith in these filters has been restored.
