"We started off with the regular system, and we were missing something. We came from having a salt system, so we knew what adding the salt system does for our water. We added the salt to our whole house system, and that made all of the difference for us. If you aren’t used to a salt system, you might not notice the difference without it. If you are, you’re going to notice it. The people at Kind are amazing! So incredibly helpful! The absolute best customer service!"
"Have had this WS installed for a couple of months now as as replacement to the saltless water conditioner. It is working great, can tell the difference in the water 100% where we really could not with the water conditioner. Repurposed the water conditioner to now have a sediment filter followed by the charcoal filter before the water softner followed by the UV light. All seems to be working. Would recommend the water softener and filters but would not recommend the water conditioner. Kind as a company has been very good to work with and I would recommend as a company."
"The Kind Water S-650 water filtration system is by far one of the most comprehensive systems that we’ve installed and are proud to offer this to our customers. The US based support staff is also a huge help for determining what system best suits our customers needs. Keep up the great work guys!"
"I like what I see. I need a plumber and no time for tha at the momemt. onetat the"
"we had success right away. no more water spots!!!"
Unfortunately, private wells are non-treated water supplies and more susceptible to contaminants and bacteria. The best way to ensure clean tap water throughout your home is to keep pollutants out of the water before it enters your home in the first place. The level of contamination and bacteria can vary from month to month and impact the level of filtration that is required.
That’s why Kind recommends upgrading to the S-650UV — featuring the latest Ultra Violet (UV) purification for complete protection. This powerful final stage of treatment uses concentrated UV light to neutralize harmful microorganisms, including bacteria, viruses, and pathogens, without adding any chemicals to your water. When it comes to the quality of water you drink and bathe in every day, there can be no compromise.
Our systems come with a limited lifetime warranty on the tanks and 7 Year Warranty on the Electronic Heads, as well as a 120-day satisfaction guarantee, This means you can return it for any reason if you are not 100% Satisfied.
Yes, the S-650 can be used with septic. There is some concern about the sodium in the salt-softener discharge, but modern efficient softeners do not use as much salt as previous era softeners. We have never received feedback from customers over damaged septic systems due to our salt-softener.
Yes, the system can be installed outside as long as the electrical components are protected from the weather. Operating temperature outside has to be between 39°F and 113°F.
You should always start with one of our Water Test. Testing the water will guarantee you are buying the correct system for your water quality problem.
The cost of your water test will be fully credited toward any system purchase.
