How It Works: Advanced Technology
Stage 1: Prefilter Cartridge (ROM-PRE)
Function: Removes larger particles and protects the RO membrane from premature fouling
Benefit: Extends the life of the RO membrane and improves overall taste of filtered water
Stage 2: Reverse Osmosis Membrane (ROM-G75)
Function: Uses high-recovery GRO technology to filter water at the molecular level
Benefit: Effectively reduces lead, TDS, and other contaminants for cleaner, safer drinking water
Stage 3: Post-Filter Cartridge (ROM-PST)
Function: Provides final filtration as water travels from storage tank to faucet
Benefit: Ensures water maintains its fresh, clean taste from storage to consumption
