5-Stage Filtration Process Explained
The GLACIER FRESH GFU03 employs a sophisticated 5-stage filtration process to deliver exceptionally pure water. Each stage targets specific contaminants to ensure comprehensive purification.
Stage 1: Sediment Pre-Filter
Removes larger particles like sand, rust, and sediment to protect subsequent filters and extend system life.
Stage 2: Carbon Block Pre-Filter
Absorbs chlorine, organic compounds, and chemicals that affect taste and odor, improving water palatability.
Stage 3: RO Membrane
The heart of the system, this semi-permeable membrane removes up to 99% of dissolved solids, heavy metals, and harmful contaminants including PFAS/PFOS.
Stages 4-5: Post-Filtration
Final carbon filtration stages polish the water, removing any remaining odors and improving taste for refreshing, crystal-clear drinking water.
