The G3.0 has an additional third-stage carbon block inner core to help enhance performance. The G3.0 has the same NSF-42 component safety certification and includes the recent NSF-372 lead-free certification.

    Easy to setup, clean and refill. Water tastes great.

  3. Patrick

    BEST WATER EVER. Have had a ProPur for years. Love it. There’s 2 of us and we only drink water, so refill every day. Plus we bought a clear blue 2.5 gallon container that goes in fridge. So you can fill that up and make more filtered water in the ProOne and always have plenty of great tasting water to drink and cook with.

    Love the shower heads also.

  4. Shashidran Rajagobal (verified owner)

    Great water taste, excellent water filter. All in 1 filters – no extras needed.
    Very good build quality, excellent product.
    Very fast world wide delivery.
    Highly recommend the ProOne and this company.

    We’ve been using this for about a month and couldn’t be happier! Water tastes amazing!!! So happy my kids don’t have to drink chemical polluted water anymore. It was definitely a good investment

  6. Jacob G (verified owner)

    Great filter! Water taste great and filters quickly with the 3 filter option. I had a pin hole on my top container and ProOne customer service was fast to get me a new hassle free.

  7. Nathaniel Palmer (verified owner)

    Great water filter, works fantastic! Currently using only one water filter, but I love the option to have three at a time when having people over!

  8. mhmaxwell (verified owner)

    ..I’ve been using Propur Filtration Systems since 2014 and just received my new Big+ System. I’m using 2-9” filters and It works great! I can highly recommend this gravity filtration system.
