SOFTENERS AND CONDITIONERS
Water Softener Reviews
Water Softeners use salt to tackle hard water issues such as scale build-up that can damage your plumbing and appliances. Read on to find out if you need one for your home and how to make the best selection.
What is a Water Softener?
Water softeners are systems that address hard water through a process known as ion exchange. Essentially, they grab the ions hard water minerals (calcium and magnesium) and replace them with harmless sodium ions. Through this process, the water is softened by removing hard minerals.
How Do Water Softeners Work?
As hard water flows into the system, it passes through a bed of resin beads that have a negative charge from sodium ions. Since the hard water minerals calcium and magnesium have a positive charge and opposite charges attract, they will be drawn to the resin beads as hard water passes through the system. The beads grab the hard water minerals and swap them with harmless sodium ions, so only softened water passes through to your home. Since water softeners rely on sodium for the ion exchange process, homeowners will need to add salt to the system on a regular basis. They also require electricity to function.

Water Softeners vs. Water Conditioners
Water softeners and conditioners are two solutions for addressing hard water that have a few differences.
Most notably, these systems work through different processes. Water softeners remove hard water minerals through ion exchange. Water conditioners don’t remove hard water minerals, they alter their chemical structure to make them harmless. Both options will address hard water, so your decision may come down to other differences between the systems.
Typically, water conditioners can only tackle minimally hard water. If your home has very hard water, you will likely need to use a water softener.
Beyond how they work, the largest difference between water softeners and conditioners is the maintenance and resources they require. Water softeners rely on sodium to perform ion exchange, so you’ll need to fill the system up with large salt bags on a regular basis and the system will also requires electricity which can add to your utility bill. As an alternative, water conditioners don’t require salt or electricity to work so they are seen as low-maintenance and more eco-friendly.
