RAW- Maifan Stone Ceramic Balls

Filtration media Mineral / pH

Maifan Stone Ceramic Balls are fired balls made from powdered maifan stone (also called maifanite), a natural feldspar-quartz rock, mixed with clay.

• Made of: Maifan stone powder and clay, fired (makers' recipes)

• Form: Ceramic balls

• Main job: Releases small amounts of minerals; may slightly raise pH

• Used in: Waslix custom layered cartridges; also sold loose by weight

What it does

Maifan stone is a silicate rock whose main minerals are quartz and feldspar. Its surface dissolves very slowly, giving off small amounts of elements such as potassium, sodium, calcium, magnesium and silicon, and it tends to move water pH toward neutral.

• Mild pH lift: makers quote outlet pH of 7.0–7.5 in one case and 8–9 in another; the figures do not agree

• Adds trace minerals: lab studies report that maifan stone releases minerals into water; the amount depends on the stone and the contact time

• No contaminant removal claimed: lab reports of metal uptake come from tests on maifan stone itself, including acidic mine wastewater, and do not carry over to a drinking-water cartridge

Evidence: limited Lab studies report that maifan stone releases minerals and moves pH toward neutral, but the only drinking-water pH figures are makers' own and they disagree. Maifan is widely marketed as a 'mineral' or 'activating' stone; independent evidence for benefits beyond its mineral content is limited.

Where it goes in your filter

Use it as an optional finishing layer near the outlet, after the layers that remove contaminants.

• Layer position: Near the outlet, after 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

• Keep in mind: Its pH effect adds to any other pH-raising layer; it can give off a little silica, which can weaken arsenic media placed after it; it removes no contaminants

Specifications

Handling & care

• Before first use: Rinse twice with clean water, as makers advise, and send the first flush to drain

• Storage: Keep sealed and dry; it is silicate rock, so keep dust down and wear a dust mask when pouring large amounts

• Replacement: The supplier gives no service life; replace it with the cartridge

Common questions

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.

Maifan Stone Ceramic Balls are made from maifan stone (maifanite), a natural feldspar-quartz rock, mixed with clay and fired. Used as an optional finishing layer near the outlet, they release small amounts of minerals and may raise pH slightly. They are marketed as a 'mineral' stone; independent evidence for benefits beyond their mineral content is limited, and they do not remove contaminants.
