Filter materials

Functional ceramic and mineral media to fill water filter cartridges.

Filter media overview Water purifier filters Filter materials

Seven functional materials in three groups. They are mixed with activated carbon or placed in a dedicated stage of the cartridge, depending on the effect you want from the water.

Documentation

RoHS certificates, MSDS, NSF/ANSI 42 certificate and test reports are available for the materials listed with these marks. Ask us and we will send the files for your product.

Mineral-forming media

Raise pH and add minerals to pure or RO water.

Magnesium ball (99%)

NSF/ANSI 42MSDSTest report

Form: Sintered spherical bead, 2 mm
Main components: Magnesium and SiO2
Typical dose: 50 - 70 g per cartridge, mixed with GAC carbon

Turns purified water (such as RO water) into alkaline water: it raises pH, lowers ORP (a deeper negative value) and generates active hydrogen to scavenge free radicals. Being sintered, it is non-flammable and keeps a stable output over a long service life, unlike loose magnesium chips or flakes.

pH control ceramic ball

RoHSMSDS

Form: Ceramic ball, Ф3 or Ф8
Releases: Calcium (Ca) and magnesium (Mg)

Alkalizes and stabilizes the pH of the water. It acts as a pH buffer and slowly and steadily releases Ca and Mg into the water. A moderate effect, typically raising RO water from pH 6.0 - 6.5 to pH 7.5 - 7.8.

Coral sand

RoHS

Form: Granule, 5 mm
Releases: Sodium (Na), calcium (Ca) and other minerals

Adds minerals to the water and improves its taste by releasing a range of minerals such as sodium and calcium.

Antibacterial media

Keep the final cartridge and the water free of bacteria. One of the two types is normally enough.

Antibacterial ceramic ball

RoHSTest report

Form: Ceramic ball, Ф3 or Ф5
Test result: 99.9% E. coli removed in 24 hours

Ceramic ball that complies with RoHS safety requirements. In a 24-hour test it removed 99.9% of E. coli bacteria (100 g of balls in 1 L of water).

SA ball (Super-Antibacterial)

MSDSTest report

Form: Spherical bead, dark brown, 7.5 mm or 10 mm
Typical dose: About 10 balls per final cartridge (about 3,000 balls per kg)

Outstanding bacteria-killing ability, with close to 100% kill rate in the manufacturer’s test report. Only about ten balls in the final cartridge are needed. Does not use nano silver.

Water-activation media

Functional ceramics that energize and activate the water.

Far-infrared ray ceramic ball (Pico TR ball)

RoHS

Form: Ceramic ball, 4 - 5 mm

Emits far-infrared rays and activates the water.

Tourmaline ceramic ball

RoHS

Form: Ceramic ball, 5 - 10 mm

Produces a very small electric current and generates negative ions (anions), which act on the water molecules through a temporary electrical discharge.
