Filtration media Mineral / pH
Alkaline Ball is a fired ceramic ball made with natural minerals that, the supplier states, release calcium into water and make it alkaline.
Made of: Ceramic with natural minerals (supplier); full composition not disclosed
Form: Ceramic balls
Main job: Raises pH and adds calcium to low-mineral water
Used in: Waslix custom layered cartridges; also sold loose by weight
As water flows past, alkaline minerals in the ball dissolve slowly. They neutralise acidity, which raises the pH and adds calcium hardness. The effect fades as those minerals are used up.
Raises pH: in another maker's published test of a similar white alkaline ball (200 g, 1.4 L/min, RO water at pH 6.0), pH rose to 8.3 at first and fell to 7.0 after 1,400 L
Adds calcium: the supplier states the ball releases calcium, but gives no amount
Can overshoot: the same maker quotes a range of pH 8–10.5, so fresh media, RO water or water left standing in the cartridge can go above pH 8.5, the top of the US EPA's recommended (non-enforceable) range of 6.5–8.5
Evidence: manufacturer data The pH figures come from another maker's test of a similar ball, not from our supplier, and we have no test data for this exact material. It is also marketed for 'alkaline' and far-infrared 'activated' water; independent evidence for health benefits of alkaline water is limited.
It belongs near the outlet, after the layers that remove contaminants, so the higher pH does not weaken pH-sensitive media such as activated alumina and iron-based arsenic media.
Layer position: Near the outlet, after carbon, KDF, resin, activated alumina and iron-based media, and before the filtration pad
Pairs well with: Activated carbon and the other contaminant-removal layers placed before it; use it instead of Calcite or MPH Alkaline Ceramic Balls, not alongside them
Keep in mind: Works best on soft, acidic or RO water; on hard water it adds little and can add to scale; it removes no contaminants

Before first use: Rinse until the water runs clear, then send the first flush to drain; new media sheds fine dust and gives its highest pH
Storage: Keep sealed and dry, away from chemicals
Replacement: The supplier gives no service life; replace when a pH test shows the outlet water no higher than the incoming water
No. It changes pH and adds calcium. Contaminant reduction comes from other layers in your cartridge, such as carbon, KDF or resin.
Both add calcium and raise pH. Calcite reacts slowly and, under normal conditions, stops once the water reaches a non-corrosive balance, while alkaline balls can push pH well above that and fade with use.
Yes, as its own layer near the outlet. Keep it after activated alumina and iron-based arsenic media, which work less well at higher pH, and use only one pH-raising medium per cartridge.
No certification is claimed for this product. Filter media can be certified for material safety (for example to NSF/ANSI 61) and complete systems for performance (NSF/ANSI 42 or 53), but we have not found such a listing for this material.
How well any medium works depends on your water, the flow rate, contact time and the other layers in the cartridge. This page describes the loose medium, not a certified filter system.
Alkaline Ball is a fired ceramic mineral ball for the outlet end of a layered cartridge. It releases calcium and raises pH, most noticeably in soft, acidic or RO water. The effect is strongest when the media is new and fades as more water passes through. It is not a contaminant-removal medium.
