Problems it Solves for Homeowners

Many homes across the country have a problem with hard water. Installing a WaterBoss 700 Water Softener is your first step toward solving this problem.

Here’s an example of a customer review on Home Depot’s website:

Alternatives to the Waterboss 700 or 900

Choosing a water softener for your house also involves looking at competing models. There are several ion exchange systems available on the market. In this case, we’re looking at the Springwell FutureSoft Salt-Free Softener and the Aquasana EQ-1000.

Springwell FutureSoft Salt-Free Softener

springwell future soft

A stand-out feature of the SpringWell Futuresoft Water Softener is that it’s salt-free. Consumers love that they can extend the lifespan of their home’s appliances while getting soft water. These systems are ideal for families that are looking for salt-free technology that also doesn’t require electricity.

See our full review of the Springwell FutureSoft Softener

This system uses Template Assisted Crystallization (TAC) instead of ion exchange methods for removing your water’s minerals. During this process, the hardness-causing mineralization converts to a crystal that can’t stick to surfaces. That way, no build-up occurs on your home’s appliances and pipes.

Aquasana EQ 1000


The Aquasana EQ-10 is another salt-free system that doesn’t require a brine tank. This softener’s stand-out feature is its ability to remove up to 975 of the chlorine taste in your water. It can do this for up to 1,000,000 gallons of water. That means no matter your water usage, this system can handle your water treatment needs.

Another stand-out feature is that you can also add a UV pre-filter sterilizing up to 99% of bacteria, cysts, and viruses. The system’s flow rate is seven gallons per minute, and its SMC technology safely and naturally removes the build-up of limescale in your house. This water softener is ideal for removing contaminants and hard water minerals to produce the purest soft water possible. 


We like the Waterboss 900 as an inexpensive ion exchange water softener because it’s an excellent choice for a family that’s living in smaller homes who are looking to reduce their water’s hardness.

We also love that this system features easy installation, it’s easy to use, and it’s affordable. Compared to the alternatives, the Waterboss is a good choice but we still think Springwell’s FutureSoft is the best option available. 

No matter if your water is from a well or municipality, you’ll find that the Waterboss 900 can meet your water treatment needs. Families can trust that every tap and water-based appliance in their home receives the water softening treatment it needs. You’ll also find that Waterboss has additional filtration solutions that adjust your water’s pH or eliminate excess iron.
