Two good options. Here’s how they differ.
Both systems soften and treat the water for your whole home, and both are installed by VK Water. The difference is how they’re built. Here’s an honest side-by-side to help you choose. Neither is a stripped-down version of the other: they’re two different ways to treat the water for your home.
