What's really in your tap water?

Chlorine & Chloramines

Municipal disinfectants dry out skin and hair, fade laundry, and give water that pool taste. The catalytic carbon bed removes them at the point of entry - every shower, every faucet.

Heavy Metals & Dissolved Solids

Lead, arsenic, nitrates, fluoride and PFAS pass right through basic pitcher filters. The RO membrane rejects 96-98% of dissolved solids - the same technology bottling plants use.

The Bottled Water Bill

A family spends $600-900 a year on bottled water and hauls jugs every week. The dedicated faucet delivers the same quality for pennies per gallon, straight from your sink.

Two barriers. One installation.

Whole-House Protection

Every shower, washer and appliance gets chlorine-free, metal-free water from the point of entry. Skin, laundry and water heaters notice within weeks.

Self-Cleaning Clack Valve

The industry-standard Clack WS1 valve backwashes the media bed automatically at night. No disposable cartridges in the pre-treatment for 5-7 years.

6-Stage RO Under the Sink

Sediment, dual carbon, a 100 GPD membrane, post-carbon polish and remineralization - hidden in the cabinet, served through an elegant dedicated faucet.

Longer Membrane Life

Because water reaches the RO already free of chlorine and sediment, the membrane lasts 2-3 years instead of one - lowering your yearly maintenance cost.

Mineralized, Great-Tasting Water

The final stage adds back calcium and magnesium and balances pH to 7.0-7.8, for a crisp spring-water profile - not flat, stripped water.

Professional Install & Service

Vontech technicians install, pressure-test and program the system, and our annual service plan keeps every stage on schedule - we track it for you.
