Description
The 3-Stage Big Grey with Stainless Steel Frame is the ultimate point-of-entry (POE) filtration solution for residential homes, borehole water treatment, and Reverse Osmosis pre-filtration. Designed to be installed at the main watersupply line, this system ensures that every tap in your home delivers clean, filtered water. With a flow rate of 3,000 LPH, it is perfectly suited for small to medium households (2–4 people), protecting your health, your appliances, and your geyser from sediment and chemical damage.
Key Features
 
Premium Stainless Steel Frame: The integrated floor-standing stainless steel frame provides maximum stability and superior corrosion resistance—ideal for outdoor or damp installations.
Complete Whole-House Filtration: ensures all water used for showering, cooking, and laundry is clean and free of chlorine.
Appliance Protection: Significantly prolongs the lifespan of washing machines, dishwashers, and geysers by removing abrasive sand and rust.
High-Flow Inline Design: No storage tank required; water is filtered in real-time as it flows into the property.
Standard 20" Jumbo Size: Uses 20-inch "Fat" filters for superior dirt-holding capacity and less frequent maintenance.
How the 3-Stage Process Works
This system utilizes a three-stage physical and chemical process to purify your water:
 
Stage 1 (PP 5 Micron): Removes large suspended solids like sand, rust, dirt, and leaves.
Stage 2 (CTO Carbon Block): Aggressively targets chlorine, volatile organic compounds (VOCs), and eliminates foul tastes or odors.
Stage 3 (PP 1 Micron): Provides final "polishing" by removing microscopic sediment down to 1 micron for exceptional clarity.
