Big Berkey Using ProOne™G2.0 Water & Fluoride filters – 7 inch

As Propur’s ProOne™G2.0 Water & Fluoride filter elements can be used in most of the Berkey systems since they are gravity based, we have put together a Royal Berkey option for you. These filters offer a non-alumina based fluoride filter media while also adjusting the pH of the water to a more alkaline 9.5.

As they do have a slower flow-rate, we recommend using your unit for a smaller household than one would usually for a Royal size so that enough water is available for cooking and drinking during the day until system is refilled overnight. (Up to 4 people).

And remember, while these do have that slower flow rate, you are getting great taste and water that is alkalised in addition to being well filtered.

Height when in use: 48.9 cm
Compact Height for travel (upper chamber nests in lower): 33 cm
Diameter: 21.6 cm
Storage Capacity: 8.5 litres

Comes with: Two 7 inch ProOne G2.0 Water & Fluoride filter elements

Filter Capacity: 2,400 gallons per pair – replace about every 12 months.

To condition (prime), install in system and run through and pour out water about 3 times BEFORE drinking  – you should be able to drink water on the 4th run.

Initial flow rate while conditioning filters can be very slow: it can take UP TO  2 to 3 days to do all 4 runs as each run through can take UP TO around 8 to 10 hours. We recommend running the water through overnight while sleeping and then emptying and filling up again the next morning, etc.  Empty the first 3 runs.

For regular usage – flow rate: It can still take 2 to 4 hours to filter through on a regular basis for the first few weeks (though flow rate may decrease to 1 hour to 30 minutes after a few days to weeks). We recommend using a larger unit for your household size and filling it up overnight or if you need to fill up during the day, do it when you will be out for a few hours.

    Two filters which are an All-in-one – water filter AND fluoride Filter element
  • Alkalising: increases pH up to 9.5
