Product Overview
The system utilizes a two-stage filtration structure designed to remove sediment, chlorine, scale-forming minerals, odors, heavy metals, bacteria, viruses, and dissolved contaminants.
Stage 1: PAC Composite Filter Cartridge
The first-stage filter combines multiple purification technologies into a single cartridge:
- PP sediment filtration
- Scale inhibition technology
- Carbon fiber adsorption
This stage removes:
- Rust
- Sand
- Suspended particles
- Chlorine
- Organic compounds
- Unpleasant taste and odor
Stage 2: 800G RO Membrane
The second-stage reverse osmosis membrane provides ultra-fine filtration accuracy of:
- 0.0001 micron
This allows effective reduction of:
- Heavy metals
- Lead
- Arsenic
- Fluoride
- Pesticides
- Microplastics
- Bacteria
- Viruses
- Dissolved solids

Smart Features Designed for Everyday Convenience
Real-Time TDS Monitoring
Water quality can change throughout the day depending on the incoming municipal water supply.
The integrated LCD display continuously monitors purified water quality through real-time TDS readings, allowing users to verify system performance instantly.
Benefits
- Continuous water quality visibility
- Improved consumer confidence
- Easier maintenance planning
- Enhanced user experience
UVC Sterilization Technology
Water purification doesn't stop at filtration.
The built-in UVC sterilization system helps reduce microbial contamination by targeting bacteria and microorganisms that may develop within the system.
Advantages
- Additional hygiene protection
- Improved water safety
- Reduced bacterial growth risk
- Enhanced long-term performance
Brushless Variable-Frequency Pump
Unlike traditional pumps, the brushless inverter motor provides:
- Lower operating noise
- Higher energy efficiency
- Stable water pressure
- Longer service life
The intelligent motor automatically adjusts operating performance based on demand, helping optimize system efficiency while reducing wear.
Automatic Water Shut-Off During Filter Replacement
One of the most common maintenance concerns with RO systems is accidental leakage during cartridge replacement.
The POM filter head incorporates an automatic shut-off mechanism that immediately stops water flow when filters are removed.
Benefits
- Cleaner maintenance process
- Reduced leakage risk
- Faster filter replacement
- Better user safety
High-Flow Performance for Modern Households
An 800G RO membrane can deliver significantly faster purified water production than traditional 400G or 600G systems.
Suitable Applications
- Family homes
- Villas
- Apartments
- Office pantries
- Commercial kitchens
- Hospitality projects
- Healthcare facilities
The higher flow capacity helps reduce waiting time and improves user satisfaction.
