PT-4.0/5 – 5-Stage Certified 36 GPD Reverse Osmosis System

PT-4.0/5 – 5-Stage Certified 36 GPD Reverse Osmosis System

The PT-4.0/5 is a certified 5-stage residential reverse osmosis system engineered to deliver clean, great-tasting drinking water directly from your tap. Rated at 36 gallons per day (GPD), this under-sink system provides enhanced pre-filtration for improved chlorine reduction and membrane protection.

Overview

The PT-4.0/5 expands on the standard 4-stage design by adding an additional carbon filtration stage before the RO membrane. This extra layer improves chlorine reduction, protects the membrane from chemical damage, and enhances overall system longevity.

Designed for residential kitchen installations, this system includes a 4-gallon storage tank, standard 2.5” × 10” filter housings, and complete installation hardware for reliable, long-term performance.

Filtration Stages

• Stage 1: 5-Micron Sediment Filter – Removes dirt, rust, and suspended solids.
• Stage 2: Carbon Block Filter – Reduces chlorine, taste, and odor.
• Stage 3: Additional Carbon Filtration – Further chlorine and chemical reduction for enhanced membrane protection.
• Stage 4: 36 GPD TFC RO Membrane – Reduces dissolved solids and a wide range of contaminants.
• Stage 5: Inline Post Carbon Filter – Final polishing stage for improved taste before dispensing.
