Aquios FS-220 Salt Free Water Softener Review

There are countless benefits to softening the water in your home – but there are so many products on the market that it can be challenging to identify the best water softener for your home.

That said, when looking for a water softener, consider the role that salt plays in your water quality. The Aquios FS-220 Salt-Free Water Softener and Filtration System is an efficient and quality whole house water system that uses a salt-free method to treat your water.

Everyone has different needs when it comes to their home’s water, which is why we make a point of recommending a wide variety of water softeners to suit different family’s unique needs.

If you are on the market for a water softener, these are the reviews to check out to help you make an educated decision. Invest in a small but highly efficient unit capable of treating and transforming large volumes of water when you choose the Aquios FS-220.

With the Aquios FS-220, you’ll get the benefits of commercial water restoration technology combined with carbon block filtration. There’s a lot to love about this system that softens and filters your water without any salt:

All-In-One System: Key Features

With advances in technology has come an increase in water technology products like advanced water softeners that treat and filter water efficiently and in style.

This is one of the slimmest water softeners on the market with everything you need rolled into one lightweight and space-saving bundle.

What’s Included: You will receive the water softener, the mounting bracket, and the inlets you need to get going straight out of the box without needing to go to the hardware store. The manual includes detailed installation instructions.

Easy-to-install with No Electricity or Programming Required: This is a non-electrical unit so that you don’t need to worry about any rewiring, placement or power outlets. There’s no programming to learn, nor will you be faced with any confusion about regeneration cycles. There are no magnets, salt, or backflush.

Conditioning, Scale Reduction, and Filtering: Your water will taste dramatically better with all the sediment and impurities removed along with any lingering traces of chlorine. The accumulation of scale that can clog up your pipes and appliances will be history, too.

If that isn’t enough, you’ll find that your water is conditioned, so soaps and detergents will perform better. Your hair, skin, and laundry will also all benefit from this modest investment which will transform your water supply.

Salt-Free System

When you check if your home has hard water and end up realizing your water is in desperate need of cleaning, you’re going to want to solve the problem as efficiently as possible.

This system gives you the efficiency and effectiveness of a salt-based option without any of the harmful consequences of using salt. Enjoy your water clean, filtered and scale-free without the expense or environmental impact of a reverse osmosis system with salt.

Siliphos: Siliphos is a food-grade polyphosphate approved by the FDA. This additive works to prevent scale from forming. It protects your pipework and appliances without your water taking on that slippery feel that some water softeners can create.

Valve-In-Head Design

There’s a bypass valve built into the head of this unit with shut-off and internal bypass functionality.

A simple twist to shut off or bypass: Should you need to turn off the water flow – when you’re changing the cartridge, for instance – twist the head to the off position. Twisting the head to bypass will help you prolong the system if you need to use untreated water at any time, which can be useful if you frequently water a large garden and don’t want to waste treated water on your grass.

High-Capacity Filter Cartridge

While these cartridges are not particularly cheap, you’ll get a great deal of functionality, and your first cartridge will be included in the bundle.

Carbon block filter: This stops carbon fines from being released into your water supply while also getting rid of sediment, the taste, and smell of chlorine, as well as organic contaminants that might otherwise taint your supply.

The lifespan is roughly six months, enough for the treatment of 40,000 gallons of water. You should rinse the filter for 5 minutes before installing it for best results.

Features Statistics

How about the statistics that count? We’ll break those down for you next:

Pressure: Recommended pressure with this unit is 80 PSI. If the water in your house comes in greater than the maximum operating pressure of 100 PSI, you will require a pressure reducer in the water line before the housing of the filter.

Temperature: The temperature range of the Aquios spans from 40 degrees F to 115 degrees F.

Capacity: While the cartridge can treat up to 40,000 gallons of water, it largely depends on how hard the water is. Expect to replace the cartridge twice a year.

Filter: The filter in this softener is rated at 5 microns, and it works for treating water hard to 22 grains per gallon.


This innovative water treatment solution has a 20-year warranty in place, clearly indicating how much faith the manufacturer puts in the product. Let’s face it: no company expects to lose out on a guarantee.

Beyond this, you’ll also have a full two months after the purchase to call in a full refund if you’re not entirely satisfied with the results it brings. You can’t ask for more than that!

The Bottom Line: Aquios Salt-Free Water Softener & Filtration System

If you’re skeptical about the expenses or the environmental footprint that comes with a salt-based water softening system, this innovative alternative from Aquios is well worth a place on your shortlist.

If you’ve been scouring for a combined unit that can give you great tasting water while also eliminating scale and conditioning your water supply, there’s no need to invest in separate components since the Aquios ticks all boxes.

As a bonus, this water softener can be installed outside. That said, you should make sure that wherever you put it, it’s not somewhere that it’s likely to drop to freezing point.

By using a food-grade polyphosphate additive rather than salt, you’ll be able to do your part for the environment while saving money on increased efficiency. You’ll also be able to enjoy fresh tasting water while you’re at it!

You might not get some of the bells and whistles of more complex models with the Aquios salt-free water softener, but in return you get a hard-hitting and reliable multi-purpose water softener with a super-slim form factor.
