If you live in an area where water hardness is high, a washing machine filter is an absolute necessity.
Continued exposure to hard water results in limescale buildup inside your washing machine, affecting the heating coil and drum. Over time, this results in breakdowns and maintenance requirements, reducing the life of the washing machine.
If you think the effects of hard water stop there, think again. Your favourite Egyptian cotton shirt feels a stiff and dull after a wash? The satin bed spread feels a bit rough on your skin? Hard-water salts are the likely suspect.
Hardness in water is caused by mineral salts – mostly calcium (Ca) and magnesium (Mg).. The mineral salts react with soap / detergent to form an insoluble precipitate known as soap film. This results in poor wash quality, and these salts stick to fabric making clothes look dull and leaving them stiff & rough.
