Why Choose the 20 Inch 3-Stage Big Blue Water Filter Housing

Standard 10 inch cartridges clog quickly on Omani municipal and borewell water. This jumbo unit takes 20″ x 4.5″ cartridges that hold far more dirt, run at a much higher flow rate and need changing far less often. The result is steadier pressure at every tap, longer cartridge life and a lower cost per litre of treated water for the whole property.

Three 20″ x 4.5″ Big Blue stages for sediment, fine sediment and carbon filtration
Reinforced food-grade polypropylene sumps with double O-ring seals

How the 20 Inch 3-Stage Big Blue Water Filter Housing Works

Water enters the first stage, where a spun polypropylene cartridge traps sand, silt, rust and scale particles down to about 5 microns. The second stage removes finer 1 micron particles and protects the last stage from premature fouling. The third stage holds a granular activated carbon or carbon block cartridge that reduces chlorine, taste, odour and dissolved organic compounds. Clean, low-turbidity water then feeds the whole property, and any downstream reverse osmosis system, water softener or UV steriliser lasts noticeably longer as a result. For background on safe drinking water parameters, see the drinking-water quality guidelines published by the World Health Organization.

Applications Across Oman and Muscat

Villas, apartment blocks, offices, mosques, restaurants, clinics, laboratories, workshops and light industrial plants all use this housing as a first line of defence. It works equally well as a pre-treatment skid ahead of a commercial reverse osmosis plant or as a simple whole-house filter on a domestic roof or ground tank line.
