2023 Buyers Guide to the Best Water Softeners

Buying your home’s water softener can be an arduous task, much like selecting a reverse osmosis system or whole house water filter. The devices seem complex and installation feels nearly impossible. But the cost of not addressing your home’s hard water will add additional cost to running your household, and may negatively impact your family’s health.

Hard water means that your water supply carries a lot of extra minerals like calcium, magnesium and heavy metals such as iron. Finding the right water softener to combat this requires consideration of these key points, which affect the water softener’s overall performance and lifespan.

Key Considerations To Choosing A Water Softener

  • Salt-Based or Without Salt: Salt-Based water softeners basically exchange the unwanted calcium, magnesium, copper, iron and more for harmless ions. This is done in the tank, so the salt isn’t in the flow of your water. When the hard water passes over salt media inside the tank, it goes through an “ion exchange.” So, this way when the water is done passing through the salt it is softer. Your water doesn’t taste salty, and your appliances are protected. Salt-Free water softeners are actually “water conditioners” because they don’t technically soften water. Instead, they remove some particles like sodium and magnesium with a filter. Then they prevent lime scale and disruption to your pipes and appliances because the unit breaks the minerals ability to bond to metals. For many homes, this is enough and will protect your appliances.
  • Water Hardness: Are you sure your water is hard? The tell-tale sign is that your detergents aren’t as effective. If you’re pulling out glasses or plates with water spots and streaks, then your detergents aren’t as effective as intended. Hard-water is probably the culprit. But, there is some grey area when it comes water hardness. If you’re looking for the best water softener for your home, start by checking your water’s hardness. There are several kits that are inexpensive. Because water softeners are expensive, you don’t want to go out, and by the biggest one out there is your water is only moderately hard. The scale on water hardness starts with “soft” and ends with “very hard.” Soft water is 0-1 grains per gallon and slightly hard is 1-3.5 grains per gallon. If you’re in this range, you could use a less intense water softener than a house that registers as “hard” in the 7.0-10.5 grains per gallon range.
  • Water Flow Rate: Finding out your water flow rate isn’t an exactly a science. The water flow rate of your home is determined by how much water is regularly used. Most people make an estimate based on these factors: How many bathrooms are in the home?How many people are living in the home? How many water-based appliances are in use?Take into consideration appliances like your washer, and the dishwasher then counts them almost like another person in the household. Usually, bigger tanks have faster water flow rates, but the biggest on this list is the Iron Pro 2. It features the fastest water flow rate available at 16 gallons per minute. If you’re really not sure and considering a salt-free system, then you’re in luck. There are many salt-free models that don’t affect the water flow rate. However, many salt based systems can track and adapt to your water flow needs.
  • Regeneration Process: Throughout our research, the “regeneration process” came up a few times. This sounds really technical but is fairly simple. This is how long it takes the water softener to completely recover from a period of hard use. Each model has a different regeneration rate. For some people, this isn’t a make or break aspect, but if you constantly use large amounts of water in your home, you could have difficulty with a long regeneration time frame. Many of the best water softeners can track and time their regeneration process. The best water softener should have the ability to track your water flow rate and time its regeneration process only when necessary. That way it uses the absolute minimum amount of water and salt necessary.

FAQs For Water Softeners

How does a water softener actually work?

It’s a simple question with a very technical answer. However, examining how a water softener works sets the salt-based and salt-free systems clearly apart. Understanding how they work can help you decide which is the best water softener for you.

A salt-based water softener uses water softener salt as a resin media. This means that as the water passes through the resin media, it undergoes an ion exchange. It removes the minerals and some of the heavy metals then, it replaces them with harmless ions. Basically, it takes out the stuff that hurts your appliances and replaces it with filler, which in the case of water is just water. When the unit is holding a large amount of calcium or magnesium, it begins its regeneration cycle.

A salt-free water softener system works a little differently. Instead of removing the particles it removes the minerals ability to bond. Where calcium and magnesium are known to attach to pipes and inside appliances, it simply won’t be possible. After chemically altering the state of the unwanted minerals the water is technically conditioned, not softened.
