British Berkefeld Ultra Fluoride Filter Cartridge (Model 8B76)

If you need a reliable replacement filter cartridge for your gravity water filter that targets municipal fluoride, harsh chemicals, and microplastics, the Doulton Ultra Fluoride Filter Cartridge (Model 8B76) is the gold standard.

As the official Doulton distributor in New Zealand, we supply genuine British Berkefeld replacement parts to customers across NZ and Australia who refuse to compromise on their drinking water standards.

Core Benefits

Your gravity water filter system is only as powerful as the cartridge inside it. Choosing a verified replacement ensures that your home or travel setup continuously removes harmful impurities without failing behind the scenes.

The Ultra Fluoride 8B76 cartridge provides multi-stage filtration by combining an outer sub-micron ceramic shell with a highly specialized carbon-based media core. This dual-action design forms an absolute physical barrier against microscopic pathogens, trapping harmful bacteria on the ceramic surface while allowing healthy, naturally-occurring minerals to pass through freely.

This is an investment in your baseline health. By swapping out your filters on time, you support your body’s natural detoxification pathways, maintain peak mental clarity, and ensure your water always tastes completely crisp and pure. At only a few cents per filtered litre, it offers massive savings over buying bottled water, while keeping plastic waste out of our natural environments across Australia and New Zealand.

Universal System Compatibility

This premium 7-inch filter candle is highly versatile and fits almost all major counter-top gravity filtration units on the market. It is fully compatible with:

• British Berkefeld Gravity Systems

• Berkey Water Filters

• ProOne and Phoenix Systems

• Purewell and Newton Gravity Systems

Important Setup Note: It is not recommended to mix Ultra Sterasyl and Ultra Fluoride filter elements within the same housing, as doing so reduces filtering efficiency.

Replacement Schedule

To maintain the filter performance, the manufacturer recommends replacing your filter cartridges in accordance with how many elements you run at one time:

• 1 Cartridge running by itself: Replace every 6 months.

• 2 Cartridges running simultaneously: Replace every 12 months

• 3 Cartridges running simultaneously: Replace every 18 months.

• 4 Cartridges running simultaneously: Replace every 24 months.

Note: If you live in an area with high sediment or cloudy water, the ceramic pore structure may slow down its flow rate early. Simply remove the cartridge, scrub the outer surface under cold running water with the abrasive side of a clean sponge to remove buildup, rinse, and reinstall. Make sure no water enters the stem.
