@hillard55,
Both are fine units but my preference would be the Kinetico. That price is cheaper than many dealers offer. Both are considered high efficiency models.
The twin tank, non-electric offers many advantages, especially with 4 people. Knowing your water will always be treated is a comfort even when usage exceeds typical water use. It uses standard mesh resins but regenerates with treated water. Having never to worry about electrical breakdowns or shortcomings is nice. It has a ten-year warranty on all parts including the resin.
The EcoWater has some nifty gadgets like remote monitoring and takes up a little less space but a little taller I think. Some units use fine mesh resin but whenever it cleans itself, it uses raw, hard water with iron. It has a 25-year warranty on some parts and one year on the resin.
I don't care for cabinet models unless space is a premium.
Either one will serve you well, especially if the company stands behind it.
What was your feeling about the presentations? Notice any differences?
