About Kind Water Systems
With a focus on cartridge whole house solutions, Kind uses state-of-the-art filter and salt-free softener technology that is unmatched in the water industry. Cartridge systems are particularly ideal because they are easy to install and take no floor space compared to tank-based options.
I personally appreciate their offerings because they are more eco-friendly without the need for chemicals or wastewater to operate. But best of all, they come at an affordable price.
“I am thrilled to have this system. No more hard water stains. I also did a taste test which proved the water is now drinkable.”

Overview
The Kind combines the best of both worlds with a salt-free softener and whole house water filter into one system. It is specifically designed to give you soft and healthy water from every tap in your house without the negative impact of salt and chemicals.
I installed one of these systems to test the effectiveness, flow rate, and durability first hand. (See the install and review video below).
Based on our lab test results, the Kind Filter And Softener Combo was able to remove 100% of the chlorine. It also did an excellent job removing 100% of heavy metals like aluminium. Hardness was reduced by over 50% to 16.0 mg/L from 38.7 mg/L. See the full analysis below.

- Before Test: See Full Analysis
- After Test: See Full Analysis
Note that with a salt-free softener, hardness minerals like calcium and magnesium are not completely removed but rather altered so they do not stick to your appliances. So the actual “hardness” results will be a mix of qualitative observations in addition to the quantitative results.
“Overall I am very pleased with the Kind. We have noticed a difference with showering and washing clothes and dishes. It has been a great improvement.”
Actual Home Owner Feedback After Install
This system is a top choice for best whole home water filter & softener combos in 2023.
System Components
- 5-Micron Sediment Filter Cartridge: The system includes a large 20″ sediment pre-filter to protect the rest of the filter cartridges. It has a durable pleated design so it is able to be washed several times before needing replacement if you have heavy sediment.
- Carbon Block Filter Cartridge: The included high-performance catalytic activated coconut shell carbon block filter is highly effective at removing city water contaminants. And since its a carbon block it won’t channel like granular carbon filters, which reduces effectiveness over time.
- eSoft Salt-Free Softener Cartridge: The proprietary Kind e-soft softener cartridge eliminates the effects of hard water without any need for salt or chemicals. And it never needs to be replaced!
- Filter Housings: The filter housings screw on and off in a matter of seconds which makes filter replacements very easy.
- Installation Kit: The nice thing about this system is it is very easy to install and it comes with all the components necessary to do it on your own. This means you will save money on professional installation or the need to buy additional plumbing.
How It Works
The Kind water filter and softener combo has three stages. It starts with water flowing through a premium 5-micron sediment filter. This extra-large 20-inch pre-filter removes silt, dirt, rust, and other debris. It will cleanse the water and help extend the life of the carbon filter in the next stage.
The high-performance Catalytic Activated Coconut Shell Carbon Block filter is highly effective at removing harmful contaminants commonly found in municipal water [1]. Its uniform pore structure increases water contact time with the carbon block. This further increases its ability to address hundreds of contaminants like:
- Chlorine & Chloramine
- PFAS (PFAS, PFOAS, PFOA)
- Volatile Organic Compounds (VOCs)
- Pesticides & Herbicides
- Heavy Metals (Lead, Copper, Chromium)
In the third and final stage, water is conditioned in the eSoft media cartridge using template assisted crystallization (TAC). Hard water minerals are treated so they can no longer stick to your plumbing and appliances. I love this system because it even removes existing scale buildup, unlike salt-based softeners that only address future scale.
Additionally, if you have issues with bacteria or boil advisories, all of the systems can be paired with a UV purifier. Ultra Violet light is able to completely sterilize microorganisms for the safest drinking water possible [2].

Overview
Utilizing a proprietary salt-free conditioning technology, the Kind salt-free water softener system is designed for worry-free water from every tap in your home. It is easy to install and eliminates the effects of hard water scale without the use of salt.
System Components
- 5-Micron Sediment Filter Cartridge: The softener system comes with a premium sediment pre-filter to protect eSoft cartridge. If you have heavy sediment, it can be washed several times before replacement to save on filter costs.
- eSoft Salt-Free Softener Cartridge: The cutting-edge softener cartridge completely eliminates the effects of hard water without any chemicals or salt. It also doesn’t create brine discharge that needs to be drained into your water supply.
- Filter Housings: The filter housing assembly easily mounts to your wall so it doesn’t take up any floor space. They screw on and off with the included spanner wrench which makes filter replacements easy.
- Installation Kit: Kind systems come with all the components necessary for a DIY install. This means you will save money on additional plumbing or professional installation.
How It Works
The Kind two-stage softening system starts with water pushing through the pleated 5-micron sediment filter. This extra-large 20-inch filter removes silt, dirt, rust, and other debris. It is the first step to cleanse the water and help protect the salt-free softener cartridge in the next stage.
The salt-free technology works through a process called Template Assisted Crystallization (TAC). Once hard water comes into contact with the eSoft media, the calcium and magnesium ions are altered. The end result is they are no longer able to stick to plumbing and appliances to cause scale buildup.
This system is great because it even removes existing scale buildup, unlike salt-based softeners which only address future scale [3]. It requires no salt or chemicals to operate so its more echo friendly. Compared to salt-based softener systems that utilize an ion exchange process and mix sodium into the drinking water supply [4].
The best part is you get all this without a drop in water pressure. The Kind system can support a house with six bathrooms and has a max flow rate of up to 15 GPM.

How It Works
Utilizing the latest in carbon filtration technology, the Kind whole house water filter reduces hundreds of impurities found in municipal water supplies. It comes with a pleated 20” sediment filter to remove silt and debris as water enters your home, which protects your system for the long-run.
The second stage is the coconut shell activated carbon filter. The uniform pore structure on the carbon block filter increases water contact time. Doing so enhances the ability to effectively address contaminants like chloramine, lead, arsenic, and more.
Municipalities and cities frequently vary the amount of chemicals used to treat water throughout the year. This cycle affects the longevity and effectiveness of a whole house filter. But since the Kind is specifically designed for city water, you can be confident it’s delivering the purest water throughout your home in any condition.

Kind Water System Installation
Installing the Kind water system is extremely easy thanks to its inline design. It contains only two connections, water-in and water-out. This means it is a DIY task that can be completed in under two hours.
We installed one of their filtration systems to test it out, and you can read the full install steps in our guide. Although a bypass is not necessary because the filter replacements are very fast, we set one up anyway.
All of the filtration systems come with an installation kit that includes all the components needed for a wall mount install. Furthermore, depending on your home, it is able to be set up both indoors and outdoors. And since it is not invasive like with tank-based models, you can even take it with you if you move.
Filter Replacements

The carbon block and sediment filters on the Kind water systems last 12 months before needing to be replaced. This is a long lifespan considering most cartridge-based options need replacing every 3 – 6 months. The salt-free softener cartridge never needs to be replaced, however. The total time to replace the filters is only 15 minutes or less.
For added savings, you can subscribe to the auto-ship program to get another 15% off. It’s a nice feature so you don’t have to keep track of your filter replacement cycle. The filters automatically show up at your doorstep once a year.
Here are the quick steps to replace the filter cartridges:
- Turn Off Your Main Water Supply: Turn off the main water supply line to your home. Note, that if you have a bypass setup, you can turn this on so you don’t interrupt your home’s water needs.
- Use Spanner Wrench To Loosen Cartridge Housing: Use the provided spanner wrench to loosen the filter housing. There will be water stored inside the housing, so it’s a good idea to place a 5-gallon bucket under the filter system to pour the water in.
- Swap Out The Filter Cartridges: Remove the old filter cartridge that is inside the filter housing. You can also place this inside the 5-gallon bucket for now. Place the new filter cartridge inside the housing making sure it is straight and seated correctly. Check the o-ring that is on the top of the housing. You should replace the old o-ring with the new one provided and lubricate it so it does not crack.
- Fasten The Filter Housing: Now that the new filter is in place and the o-ring replaced, you can secure the filter housing back onto the manifold. Hand-tighten it at first to make sure it is not cross-threaded. Once it is fastened all the way, used the spanner wrench to snug it up, but be careful not to overtighten.
- Turn Back On Main Water Supply: Slowly turn back on the main water supply and check for any leaks around the filter. If there are no leaks, go ahead and turn the water supply on all the way. If you turned on a bypass at the beginning, make sure to turn that off now. And that’s it, you just replaced your filter!
Key Considerations For The Kind Systems
Here are some key factors to consider when you are looking for the best whole home filter or Salt-free softener.
- Hardness Level: Salt-free softeners work fantastic for city water sources with light or moderate hardness levels (less than 15 PPM of hardness). This is especially true in areas where ion exchange softeners are banned like certain parts of California. However, if your water supply has extremely hard water, a salt-based water softener will deliver the results you are looking for.
- Water Supply: The Kind Water System is designed specifically for city water contaminants. A specialized well water filtration system is more suitable if you have well water.
- Space: Cartridge filter systems take up very little room. Compared to tank based systems, you can fit the Kind systems in tight quarters because they are wall mounted and take no floor space. This is especially true of salt-based softeners that come with an extra brine tank to hold the required salt.
- Cost: Staying within your budget is critical when looking for the best whole-house filter and softener solution. The good news is the Kind systems are very affordable when compared to their competitors and to tank-based systems. If you are on a tighter budget, the cartridge based system is the way to go.
Kind Cartridge Filters Vs Tank Based Systems
When comparing a cartridge filter to a tank-based system, there are some things to know. Both serve a purpose with their respective pros and cons. Although the Kind is affordably priced, it still checks off a lot of the boxes in terms of performance, warranty, ease of installation, and customer support. Below is a table summarizing the comparison between cartridge vs tank filter options:
