Many have asked the difference between the different types of drinking water filters they could use in their homes, at work, or at school.

Cation-Exchange Softener:

• Typically used to soften hard water (water containing excessive amounts of calcium and/or magnesium) by ‘trading’ minerals with a strong positive charge for those with a weaker positive charge.
• Often referred to as ‘water softeners’.
• You will find most systems of these water hardness treatment systems functioning as whole-house water filtration systems.
• These systems effectively remove calcium and magnesium (water hardness) which can build up and leave depositis in plumbing and faucet fixtures over time. Water softeners can also remove contaminants such as barium which can cause health problems in humans.
