Why choose the iSpring RCC7P-AK Under Sink 6-Stage RO Dual Filter + Softener?

The next name on this list of best water softeners to consider this year is the iSpring RCC7P-AK Under Sink 6-Stage RO Dual Filter+Softener.

This model packs a big punch regarding water filtration, water softening, reverse osmosis, and price.

Here are some more things you need to know about this water softener + water filter:

  • DIY installation by most users, the entire system fits nicely under a standard kitchen sink.
  • The device features a noiseless booster pump that ensures optimal pressure to the RO membrane at all times;
  • Re-mineralization restores just the right proportion of healthy minerals.
  • The RO membrane provides clean water to a large family.
Pros Cons
Best under-sink dual water filter + water softener You may need a whole house water filter if water hardness is through the roof
DIY installation backed up by stellar technical support
Best water softener for the money
Built-in booster pump raises low incoming water pressure


If drinking water, stained dishes, dry skin, and bad-tasting or bad-smelling water are your main concerns, then the iSpring RCC7P-AK Under Sink 6-Stage RO Dual Filter+Softener is the device you want to consider this year for municipal or well water. It has few competitors in the water filtration department.

Given the poor water quality in the United States, this RO filter + water softener combo is the best money can buy if you deal with a handful of water pollutants, contaminants, toxins, heavy metals, and water hardness. Its greatest advantage is the compact design that allows you to install it under the sink. In other words, it works well in both homes and city apartments/studios.

The iSpring brand is also a good reason to include this unit on your shortlist of water softeners to buy this year. The company makes some of the best under-sink reverse osmosis water filters on the market.

However, if you test your water hardness and you want to make dramatic changes to your home’s water hardness, you may want to look for a water softener boasting a more significant grain number.

Best Water Softeners Alternatives and Other Water Treatment Systems for Your Home

A water softener as a standalone device works best when you want to intervene upon the hard water in your area that does not also require filtration. You can also look for shower filters for hard water if you do not like bathing with hard water either.

What is Template Assisted Crystallization?

Template Assisted Crystallization (TAC) technology, although not new, but on the rise, is a salt-free alternative to conventional salt-based water softening. One of the products on our list – the Watts OneFlow + Salt-Free Scale Prevention and Water Filtration System – uses TAC for water softening.

The process is similar to conventional water softeners, but not quite. Such a water treatment system does not use ion exchange and does not replace the hardness minerals in the water with sodium. A TAC system modifies the structure of the minerals, preventing them from adhering to pipes and appliances and thus eliminating limescale.

TAC water softeners, in short, do not create a separate stream of wastewater. It simply transforms the hardness ions into crystals. The crystals are still in the water, but after the crystallization process, are less dangerous from a hardness point of view. 

A hybrid between conventional water softeners and water descalers (that we will discuss immediately), TAC water softening systems have a few drawbacks.

  • Your water is just as hard as before the treatment, it just doesn’t affect your pipes, plumbing, faucets, and appliances anymore.
  • TAC water systems are vulnerable to iron, manganese, and other types of sediments and impurities. For this reason, you should combine a TAC water softener with a pre-sediment filter, an iron filter and/or a whole house water filter with carbon technology to protect the TAC systems at the same time.

In conclusion, TAC water softeners leave the healthy minerals in your water, do not create a salty brine that goes down the drain, are more environmentally friendly, consume less energy to work, and are more affordable than salt-based water softeners. Since they do not require regeneration with the help of salt pellets and take little room, these water softening systems are becoming increasingly popular. 

What Are Water Descalers?

Just as TAC water softening systems, water descalers are salt-free water softeners using electrical impulses or magnet technology to change the physical properties of the hardness minerals in the water.

A descaler is a small, compact unit you can install in any house or apartment. As the water passes through its field of influence generated by electricity or magnetic fields, the water descaler modifies the structure of the calcium and magnesium ions. In other words, a descaler does not replace or remove the hardness minerals, but leaves them there in a different shape.

This modification prevents these minerals to adhere to pipes, plumbing, faucets, or appliances. You will not have limescale anymore, but still enjoy healthy minerals in your water.

Our recommendation of best water descalers to consider this year are the Eddy Electronic Water Descaler – quite the classic when it comes to electronic water softeners – and the iSpring ED2000 Whole House Salt-Free Electronic Descaler Water Conditioner.

As you can easily understand, water descalers are an eco-friendly alternative to conventional water softeners. They consume little energy, are easy to install, require little to no maintenance, are quite affordable, and do not take space. 

Understanding These Best Water Softeners’ Tech Specs and Features

Now that we finished the water softeners reviews and discussed water softener alternatives, we want to make sure you understand a few things about these devices, because we saw plenty of misconceptions running around, confusing even the experts.

What is the Difference between Water Filters and Water Softeners?

For starters, as we mentioned with a previous occasion when we discussed the best whole house water filters to consider this year, a water softener and a water filter are not the same things. On the contrary, they work best together. A water softener also shields your plumbing from particles, making the system more efficient and ensuring that you drink and use clean, safe water.

People living in areas with polluted and hard water combine the two systems (water filter first and water softener second) to make sure they drink and use clean, safe water. 

If you want to make sure you do not drink softened water coming from the conventional softener, we recommend you install an under-sink reverse osmosis water filter as well. This device is capable of removing 99% of the sodium in your water, making drinking water taste great.

If you want to learn more about combining different types of water filtration technologies, water softening, and water conditioning, check out our guide on how water filters work. There, you will also find a table helping you to match the water problems in your home with the best types of filters and home water solutions!

Now that we made this clear let’s focus on the tech specs and features you should consider before you buy any of the best water softeners we analyzed today.

Water Softeners’ Tech Specs and Features to Consider

  • Size: Just like water filters, water softeners have to fit in their designated places. Some are large (industrial size), and you have to make room for them. Some are small and slick enough to fit under the sink or in your bathroom to treat water, so it does not stain, smell, or taste funny.
  • Weight: It is an essential factor especially when you have to install the device by yourself or carry it around.
  • Flow rate: The standard for proper water flow rate in a home for a family is around 10-15 gallons per minute (GPM). Water softeners should not interfere with the water flow rate in your home.
  • Softener Capacity: Measured in grains, it describes the amount of water hardness it can remove before it needs to regenerate. A “grain” of hardness represents 1/7000th of a pound of dissolved particles (calcium, magnesium, etc.). As you can figure out, the higher the grain number, the more efficient the water softener.
  • Warranty: Measured in years and usually offered by the manufacturer.

Salt Water Softeners vs. Salt-Free Water Softeners

As we discussed above, the majority of water softeners you find on the market are salt-based. A great advantage is they completely remove calcium, magnesium, etc. from your water before you even turn on the faucet. The downside is you have to pay attention to stock on the salt they need to work correctly.

Salt-free water softeners do not use chemicals to soften the water (thus appealing to health-concerned people and environmentalists), but they do not remove particles in the water, they neutralize them. In other words, they still expose you to water hardiness, even if it is in a neutral state. However, with the current bans and restrictions on water softeners, some of the best eco-friendly choices you have are TAC systems and water descalers.

Remember to contact the manufacturers in case you have more questions about these top-rated water softeners.

If you want to learn the hardness of your water and what is the best water softener for your home, we recommend you purchase a water hardiness kit and use it following the instructions.

For instance, iron may be the biggest problem with your water, so you should focus on getting an iron water filter, especially if you rely on well water for your daily needs!

Some reverse osmosis water filters also deal quite well with eliminating the hardness minerals, becoming good alternatives to salt-based water softeners. However, if you have very hard water in your area, you should mix activated carbon filters, water softeners, and reverse osmosis filtration.

The benefits of having a water softener to counter the adverse effects of hard water

  • Healthier water to drink;
  • Softer skin and hair;
  • Stain-free surfaces;
  • More efficient water-using appliances from an energetic point of view;
  • Significant reductions in the amounts of soaps and detergents you use.
