Leaf Home UV Water Purification System Review: Is It Worth It?

How Does the Leaf Home UV Water Purification System Work?

The system uses a UV-C lamp inside a stainless-steel chamber. As water passes through, the light breaks down the DNA of microorganisms, making them harmless — without adding chemicals or changing taste. A built-in 5-micron sediment filter removes particles that could block UV exposure, ensuring maximum disinfection.

Where and How Is the UV System Installed?

The UV system is installed after your main filtration equipment — such as sediment or carbon filters — to ensure clear water reaches the UV light. It’s especially useful for well water homes or areas prone to biological contamination. Installation is handled by Leaf Home’s trained professionals for optimal safety and efficiency.
