If you want the best for your home, start with the water you drink. While basic carbon filters can improve taste, they can’t achieve complete purification. A Sterling Reverse Osmosis (RO) system delivers truly clean, safe, and great-tasting water—right from your tap.
Learn how Sterling’s advanced RO technology outperforms standard filters and provides a long-term solution for your family’s health and comfort.
What is a Reverse Osmosis System?
A carbon filter removes chlorine and improves taste, but it only reduces total dissolved solids (TDS) by about 10–15%.
Sterling RO system goes further, filtering water at the molecular level for superior results.
Sterling RO Advantages:
- Multi-stage filtration removes up to 97% of TDS
- Removes harmful contaminants like lead, arsenic, fluoride, and nitrates
- Advanced membrane technology purifies for crisp, refreshing water
This system pushes water through a special semi-permeable membrane, blocking unwanted substances while allowing only pure water through.
