Best Overall: GE 40,000 Grain
This top pick for best overall water softener will take care of the entire home. While liquid and pellet softeners are great for specific tasks like laundry, they are too limited to handle a home’s whole water supply. The GE 40,000 Grain, however, has the capability to tackle every watering task since it hooks up directly to the plumbing, filtering the water well before it reaches a faucet.
The water softener removes around 125 grains per gallon of hard materials such as iron using its salt-storage capacity of 230 pounds. For some customizability, it comes with a digital display with programmable settings, an alarm, and memory for saving your preferred settings. GE’s SmartSoft technology adaptively learns the home’s standard water usage so it can better adapt the softening process to things like laundry and bathing automatically.

Best Pellet Water Softener: Diamond Crystal Soft and Bright
Whole home water softening systems require a softening source such as salt to get the job done. Typically, this can involve dumping pounds of specifically formulated salt directly into a brine tank. Since this can get rather messy, a good alternative is a salt pellet like the Diamond Crystal Soft and Bright which comes as a single, packed unit of salt.
When placed in the brine tank, the pellet will naturally dissolve into the water to automatically soften it while in use. Each pellet contains 99.8% pure salt so you don’t have to worry about harmful chemicals getting into the water. Once the pellet runs out, simply add a new one to keep the system running.

Best Electronic Water Softener: Eddy Water Descaler
An electronic water softener is the best option to consider when you want a modern way of removing minerals from the water. Electronic softeners such as the Eddy Water Descaler produce an electromagnetic wave that naturally breaks up minerals in the water as it passes through the pipes in a home. Compared to salt, this process can handle a variety of minerals without any leftover particles in the water.
The unit hooks up directly to the existing plumbing and filters the water without any need for salt or other chemicals. Specifically made for removing calcium, magnesium, and manganese compounds, the softener does a good job of dealing with limestone buildup that can damage tubs, sinks, showers, and other fixtures hooked up to the plumbing.

Best Heavy Duty Water Softener: Aquasana Rhino 5-Stage
Large-scale water softening can be necessary for big homes or businesses where the quality of the water really matters. Liquid and pellet softeners will simply fail for these large tasks.

Should you need the most in terms of capacity, the only real option is the Aquasana Rhino 5-Stage.

Beyond just softening, the filtration system also removes chlorine, heavy metals, pesticides, and other chemicals that are harmful to the water and air during evaporation. The system doesn’t rely on any electricity, so installation is as simple as hooking it up to your existing plumbing.
