Does the tap water in your home have a metallic or somewhat sour taste?
If yes, you may be one of the many American households that receive acidic water contaminated with heavy metals.
Sounds hazardous?
It can be! Regular consumption of acidic water contaminated with heavy metals can put you at risk of heavy metal poisoning and a range of other health issues.
Our alkaline water treatment system, Defiant, can help avoid them and make the water taste good.
The Next-Gen alkaline water filtration system for your home

Salt-free water conditioning system for the whole house
Are you concerned about the extra sodium a water softener adds to your diet?
Though it is not much and poses no health risk to most healthy individuals, it may be a problem for those required to maintain a low-sodium diet. This can put them in a tricky situation with regard to the use of water softeners.
It shouldn’t, though, because there are salt-free water treatment systems available as well.
Compact design for smaller spaces
Just because you live in a studio apartment or do not have enough empty space for a water softener system doesn’t mean you should continue using hard water and brace all the plumbing, skin, and hair issues it leads to.
You can improve your home’s water quality, taste, and smell without allocating a large area to a water treatment system or making your small space look cluttered through an All-in-One Cabinet Style Water Softener.
Introducing Smart Digital Valve Water Softeners
Knowing that the cost of owning a water softener can be too high for some people; we are introducing a series of advanced digital water softeners. Outperforming their analog predecessors by a big margin in cost, efficiency, and ease of maintenance, these smart water softeners will make water purification a seamless experience.
Our innovative digital water softeners come with several unique features that make them stand out and a perfect fit for your home regardless of their size and plumbing design. These include industry-size inlet and outlet yokes that allow them to be installed in your existing plumbing system without any modifications. Our smart water softeners also come with a detachable bypass valve, hydraulic meter, and slick, space-saving design.
