    What is Hard Water?

    Hard water is water that has a high concentration of dissolved minerals, primarily calcium and magnesium. These minerals are picked up by water as it flows through rock formations, such as limestone and chalk, and dissolves the minerals along the way. The level of hardness in water is measured in grains per gallon (gpg) or milligrams per liter (mg/L).

    How to Filter Hard Water

    The degree of hardness in water can vary depending on where you live. Some areas may have water that is slightly hard, while others may have water that is very hard.

    Hard water is a term used to describe water that contains high levels of minerals, particularly calcium and magnesium. These minerals are naturally present in the earth’s crust and can dissolve in water as it passes through rocks and soil. The concentration of these minerals determines the hardness of the water. While hard water is not considered harmful to consume, it can wreak havoc on your home’s plumbing system and appliances. This is due to the fact that when hard water is heated or evaporates, it leaves behind mineral deposits known as limescale. These deposits can build up over time, clogging pipes, reducing water flow, and damaging appliances such as water heaters, dishwashers, and washing machines.

    The hardness of water is typically measured in grains per gallon (GPG) or parts per million (PPM). Water with a hardness level below 1 GPG is considered soft, while anything above 7 GPG is considered hard. It is important to note that the hardness of water can vary depending on your location, as different regions have different geological compositions. Understanding the level of hardness in your water is crucial in order to determine the best course of action to combat its

    The Negative Effects of Hard Water

    The presence of hard water in our homes, while often overlooked, can have a profound impact on both our wellbeing and our living environment.
