Abstract
The present technology provides a method for preparing an acid-reducing filter that includes depositing a mineral blend layer to a filter substrate, where the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1, the mineral blend is free of soluble halide or hydroxide salts of alkali or alkaline earth metals, and the mineral blend layer is insoluble in water.
Claims18
A method for preparing an acid-reducing filter comprising:
- depositing a mineral blend layer to a filter substrate, wherein:
- the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1;
- the mineral blend layer is free of soluble halide or hydroxide salts of alkali or alkaline earth metals;
- and
- the mineral blend layer is insoluble in water.

A method for preparing an acid-reducing filter comprising:
- combining a mineral blend comprising calcium carbonate, magnesium carbonate, and insoluble fiber materials with a solvent to obtain a material matrix;
- depositing a layer of the material matrix to a substrate;
- and
- separating the solvent from the material matrix, wherein:
- the mineral blend has a weight ratio of calcium carbonate to magnesium carbonate of about 1:10 to about 10:1 by weight of the mineral blend, is free of soluble halide or hydroxide salts of alkali or alkaline eath metals, and is insoluble in water.
