5 Stage Reverse Osmosis Water Filter [2025 TX Model]

Ecosoft Standard 5-Stage Reverse Osmosis (RO) System delivers crisp, great-tasting water straight from an under-sink setup. It combines sediment and carbon pre-filtration with a 50 GPD RO membrane and a final post-carbon polish to reduce chlorine taste/odour, pesticides, heavy metals, fluoride and more for everyday drinking, cooking and coffee.

What the 5 stages do

1. Sediment (5 µm) – traps rust, sand and particulates
2. GAC carbon – reduces chlorine and organics
3. Sediment (1 µm) – fine particulate polishing
4. RO membrane (50 GPD) – reduces TDS incl. fluoride & heavy metals
5. Post-carbon – final taste & odour polish
