Stage 4: Reverse Osmosis Membrane
Membrane for the main impurity removal
- The membrane has pores which are so small that only pure water makes it through to the other side, effectively removing undesirable contaminants like Nitrate, Fluoride, Arsenic and Salt.
- Lifespan depends on the level of impurities in water and incoming pressure, but under normal circumstances the membrane is expected to last 2-4 years.
