Diamond Ultra Filter - Whole-House System
The Best Whole-Home Water Filter
Get clean, safe water from every tap in your house with the Honest Water Filter Diamond System.
It’s powerful, easy to use, and built to last.
Long-lasting: Field tested to treat up to 1 million gallons.
Super clean water: Reduces 99.99% of bacteria, cyst, viruses, and other tiny particles.
Low maintenance: It cleans itself and runs efficiently, saving you time and money.
Works anywhere: Great for city water or well water (just need a simple well report).
Proven quality: Fully certified to meet strict safety and performance standards.
Upgrade option: Add our Silver Plus filters to reduce chemicals and prevent scale buildup.
Municipal water systems do their best—but some contaminants can still slip through. Bottled water helps for drinking, but not for bathing, cooking, or washing.
The Diamond System gives you better water everywhere in your home, protects your plumbing, and helps you ditch the plastic bottles.
