How It Works

Five-Stage Filtration for Pure Drinking Water

Reverse osmosis pushes water through a semi-permeable membrane with pores of 0.0001 microns. Only water molecules pass through. Lead, PFAS, arsenic, chromium, fluoride, nitrates, bacteria, and viruses are rejected. The result is water that is 95-99% free of dissolved contaminants.

The 5-Stage system stores purified water in a dedicated tank under the sink, ready at a dedicated faucet in your choice of five finishes. An alkaline remineralizer is always included to balance the pH and add beneficial minerals back into the purified water.

Stage 1: 5-micron sediment pre-filter
Stage 2 and 3: Double NSF carbon block filters (removes chloramines, THMs)
Stage 4: NSF thin film composite RO membrane (100 GPD, 95-99% rejection)
Stage 5: In-line NSF coconut shell GAC polish
Alkaline remineralizer included (always)

Benefits

What Changes After Installation

Proven filtration performance with pure, alkaline water at a dedicated faucet.

Removes 95-99% of Contaminants

The RO membrane rejects lead, PFAS, arsenic, chromium, fluoride, nitrates, bacteria, viruses, and heavy metals at 95-99% efficiency. DFW tap water typically runs 200-400 ppm TDS. After RO, it drops to 10-50 ppm.

Removes PFAS and Lead

PFAS (forever chemicals) and lead are two of the most serious contaminants in DFW water. The RO membrane removes both at 95-99% efficiency, providing meaningful protection for your family.

Alkaline Water Included

The built-in alkaline remineralizer adds calcium, magnesium, and potassium back into the purified water and raises pH to a natural 7.5-9.0. Better taste and better hydration.

Dedicated Drinking Water Faucet

A separate faucet mounted at the sink delivers pure RO water on demand. Choose from five finishes to match your kitchen.

Removes Chloramines from Drinking Water

The double carbon block pre-filtration stages specifically target chloramines, the disinfection chemical used by DFW utilities that standard GAC cannot effectively remove.

Annual Filter Replacement

All five filter stages are replaced once per year in a straightforward service visit. Filter maintenance keeps the system performing at full efficiency.
