In this 3-in-1 review, we are going to check out the Aquios AQFS220 salt-free water softener and whole house filter as well as the Aquios AQFS220L and AQFS220C which are two slightly altered versions of the AQFS220.
All 3 promise to reduce sediment and chlorine in water supplies, plus the accumulation of limescale on pipes, fixtures, and appliances. Iron staining can also supposedly be prevented.
Let’s find out if there is any truth to that!
First of all, how do the Aquios AQFS220, AQFS220L, and AQFS220C work? Well, they are a combination of whole house water filter and salt-free water softener.
The softening component uses polyphosphate, a food-grade and FDA approved additive, that conditions hard water triggering an anti-scaling effect which keeps calcium, magnesium, and other hardness minerals in solution. How? The polyphosphate binds them so they can’t stick to one another nor to pipes and other surfaces (the method is backed by science).
As for the filtration component, the Aquios AQFS220 uses a 5-micron (nominal) carbon block filter that eliminates sediment, dirt, and chlorine among a handful of other impurities to mainly improve water aesthetics.
The only difference to the AQFS220C is that it comes with a clear rather than a white filter housing which allows you to determine the current state of the filter cartridge at a glance.
The AQFS220L on the other hand uses a 1-micron (nominal) carbon block filter instead of the standard 5 microns. The 1-micron version will remove more chlorine taste and odor for a longer period (more on this below) and also reduce potentially harmful VOCs, pesticides, chloramines, and cysts. Bottom line: Your water will be of higher purity and therefore healthier to drink.
You should keep in mind, however, that the AQFS220L is not recommended for well water applications unless you install an additional pre-filter. Otherwise, cartridge life will be shortened significantly and you are likely to see a huge drop in water pressure and flow soon.
By the way, Aquios full house water softener and filter systems can provide up to 12 gallons of water per minute, so enough for larger families.
Max hardness level is 30 grains per gallon.
What are the benefits of using a salt-free water conditioner vs. a salt-based water softener?
No salt means no regeneration and no brine. In other words:
Besides, the phosphate sequestering process minimizes the risk of discoloration and staining from iron etc. And, according to Aquios, it also dissolves hard water deposits that may have already accumulated in your plumbing system and appliances.
Lastly, Aquios systems are covered by a warranty that lasts 20 years.
The Aquios AQFS220 and AQFS220C remove sediments down to 5 microns in size and chlorine.
The AQFS220L removes sediments down to 1 micron, chlorine, VOCs, pesticides, chloramines, and some cysts.
All 3 systems reduce the scaling effects of hard water.

Aquios recommends installation be performed by a plumbing professional. However, taking into account that we have a very compact design, you should be able to set up the whole house water softener and filter combo yourself without any issues if you are handy around the house. The process isn’t overly complication.
Plus, the system features a built-in bypass integrated into the housing head. This makes installation a lot easier. The manufacturer says that the average DIY installation takes about two hours.
Tools and materials needed for installation:
How to install the system:
Maintaining an Aquios water conditioner is simple. All you have to do is replace the softening/filtering cartridge once it has reached its capacity.
The cartridge of the regular AQFS220 is rated at 15,000 gallons of chlorine removal, the AQFS220L cartridge at 45,000 gallons – which is not a whole lot. Depending on how much water you use, we estimate around $160-420 for annual replacement cost.
To change the filter cartridge:
Here is a link to the official manual:
https://www.aquios.net/publications/manuals/220Series/Online/index.html
The manufacturer states that the system is certified to NSF/ANSI Standard 42, which is the standard pertaining to the reduction of chlorine taste/odor and particulates.
We couldn’t find any documentation online to verify this.
The Aquios AQFS220 has no earlier product versions.
One major issue is that too many customers saw a huge drop in water pressure and flow rate soon after installing one of Aquios’ whole house water filters/softeners. The reason here is that the cartridges tend to clog up quickly.
While the supply is reasonable for a new cartridge, after one month of use it’s totally unacceptable in some cases. As a result, cartridges have to be replaced much more frequently which is not only a hassle, it also skyrockets the cost.
Speaking of, the regular AQFS220 filter element is rated at no more than 15,000 gallons of chlorine removal. At around $70 each, this can easily add up to more than $450 a year if we assume annual water consumption of around 100,000 gallons which is pretty average for a family of 4. The AQFS220L performs much better here.
What’s more, a handful of customers had problems with leaking systems, especially from the housing and the bypass valve when activated, and were disappointed by unresponsive customer service. This is certainly a concern, and something you’d want to examine closely should you purchase the system.
A large number of users had leaking issues with the AQFS220C filter in particular, from the clear housing. It makes sense to avoid this model if you’re planning on purchasing the Aquios system.
The polyphosphate additive is most effective at a pH-range between 8 to 10. This might explain why some users did not seem to get any softening benefits.
Personally, we don’t like the idea of adding polyphosphate into our water. Sure, the salt is food-grade approved and tasteless, but there are other water conditioning methods out there that don’t add anything which we prefer.
All in all, the Aquios AQFS220, AQFS220C, and AQFS220L full house water softener and filter systems do their jobs for the price, IF all water conditions and requirements are met (the series is best for regular-sized households on city water with a pH of 8 to 10).
Then you will not only get better-tasting drinking water, your hair and skin will also feel better, your clothes will look noticeably more colorful, your soaps and detergents will lather more easily, and you will see less deposits on faucets and other fixtures and surfaces.
Our rating: 3.0 stars.
Let’s compare Aquios water treatment systems to the SpringWell CSF which is another whole house water filter and salt-free softener.
The SpringWell CSF uses a 5-micron sediment filter and a tank filled with catalytic carbon and KDF filter media. Another tank uses TAC media. As such, the SpringWell removes sediments, chlorine, chloramine, volatile organic compounds, pesticides, disinfection byproducts, and other organics. KDF reduces water-soluble heavy metals like lead and prevents the growth of microorganisms. The TAC media conditions hard water minerals so they crystallize and can’t form limescale deposits (up to 99.6% scale reduction, 81 gpg max hardness).
Simply put, the SpringWell CSF provides a much more thorough filtration process when compared to the Aquios. And, it’s suited for much higher hardness levels without adding anything to the water.
On top of that, we have a filtration capacity of 1,000,000 gallons and annual cost of no more than $40. Flow rates range from 9 to 20 gpm (enough for very large homes), depending on which unit size you choose.
Did we mention the 6-month satisfaction guarantee in case you are not satisfied and the limited lifetime warranty?
We clearly prefer the SpringWell CSF over the Aquios.
