Alkaline Filter Cartridge

The Biocera alkaline antioxidant filter cartridge is an inline cartridge which alters the properties of filtered water. While water run through reverse osmosis or carbon filtration systems helps purify water, they have the negative effect of leaving the water mildly acidic; the Biocera inline filter, however, alkalises water and stimulates the release of molecular hydrogen.

Most mineral cartridges do not provide an antioxidant effect; but the Biocera inline cartridge is different.

The cartridge allows you to quickly and easily turn your existing reverse osmosis or carbon-filtration system water into health-promoting alkaline antioxidant water.

The cartridge is simple to fit and enhances the properties of filtered water without sacrificing the crisp, smooth taste. After all, who doesn't want the water they drink to be clean, pure and contaminant-free?

Why Settle for Filtered Water? 

Water exiting a typical reverse osmosis system is devoid of beneficial alkaline minerals and usually has a slightly acidic pH; it lacks structure and is in essence ‘dead’ water. By adding this extra stage to the filtration process, you’ll transform your drinking water into ‘pure’ alkaline water with a healthy mineral content.

However, this is not just a remineralisation cartridge: as well as adding vital minerals back into drinking water, the bioceramics stimulate the release of molecular hydrogen. Much research has been devoted to molecular hydrogen in recent years, and the benefits of drinking hydrogen-rich water are spreading like wildfire as awareness grows. The Biocera Alkaline Inline Filter Cartridge is one of very products on the market to give water which is both alkaline and hydrogen-rich!

How the Inline Filter Cartridge Works

The Biocera alkaline antioxidant cartridge uses several combinations of mineral crystals formed into bioceramic balls. As the water passes through this filter, it is changed in several ways. In particular, the cartridge has the following effects:

• Increases the pH of filtered water, typically to between 8.5 and 9.5.

• Changes the water's Oxidation Reduction Potential (ORP) to between -100mV and -250mV. This gives the water antioxidant properties. The antioxidant effect is due to the release of molecular hydrogen, which research is proving to be a highly powerful antioxidant.

• Reduces the size of the water molecule clusters, so that it is more easily absorbed in the body.

• Infuses the water with beneficial alkaline minerals such as potassium, magnesium and calcium.

Thanks to this cartridge, you can enhance your purified water with additional valuable properties. The special filter media in the Biocera alkaline antioxidant cartridge enjoys NSF certification. This is an international standard focused on product safety. Biocera are one of the leading developers and suppliers of bioceramics for water treatment and environmental enhancement.

Installation is Easy

When you buy your alkaline inline cartridge, we supply it with pipework and holding clips so that it can be readily fitted to your existing filter system. The filter cartridge is typically changed annually if used in a standard domestic filter system. 

Purifying water is great for eliminating contaminants, but if you want the same clean taste without sacrificing minerals, molecular hydrogen or an alkaline pH, add the Biocera filter cartridge to your current system. You won't regret it.

Further Information

 The alkaline antioxidant filter cartridge contains a special blend of the following ceramics:


Alkaline Antioxidant Minerals: Makes the water more alkaline and changes its Oxidation Reduction Potential, giving it antioxidant properties. As the water passes through the filter, it reacts with the special media to release molecular hydrogen, a powerful antioxidant. 


Antibacterial Ball: Helps to reduce pathogens and facilitates the uptake of heavy metal ions.

Tourmaline: Reduces water molecular cluster size and emits far infrared rays known for their healing properties.

The ceramic materials are manufactured by Biocera, one of the world's leading companies in the development of bioceramics for healing purposes. The ceramics have won NSF approval (safety standard), the first company to have gained this international safety approval standard for their ceramic minerals.

The alkaline antioxidant filter cartridge is 230mm long. It is easily fitted horizontally before the final carbon filter of your existing filtration system. The filter is designed to treat 4,000 to 5,000 litres of water before requiring replacement (approx 1 year for the average household).

You can buy our alkaline antioxidant cartridge from our online shop, or alternatively call us on 01764 662111.


To turn your existing reverse osmosis or carbon filtration system water into a filtration system capable of providing you with health-giving alkaline, antioxidant water, simply fit this alkaline, antioxidant filter cartridge before the final carbon filter of your existing filtration system using the fittings provided.


This alkaline, antioxidant filter cartridge contains a special blend of the following ceramics:

1. Alkaline Antioxidant Minerals, which make your water more alkaline and change the oxidation reduction potential of your water.

2. Pi Minerals, which increase water absorption and natural healing ability.

3. Tourmaline, which reduces water molecular cluster size, and emits far infrared rays which are thought to have healing properties.

The ceramic materials are manufactured by Biocera: one of the leading companies in the development of bioceramics for healing purposes. The ceramics have attained NSF approval (safety standard). Biocera are the first company to have gained this international safety approval standard for their ceramic minerals.

Each filter is supplied with 2 x 1/4" union connector and 1/4" pipe to connect to your existing filter.
