摘要：
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.
