Tap water can contain chlorine, hard water minerals, and dissolved substances that may affect taste, smell, and everyday drinking quality. Other Water helps customers better understand their water quality with TDS1 testing support and countertop reverse osmosis filtration.
Chlorine is commonly used during water treatment and can affect the smell and taste of drinking water.
Minerals in hard water can contribute to scale buildup in kettles, appliances, and everyday kitchen use.
