Maintain peak performance and pure, great-tasting water with the genuine NU Aqua Replacement Reverse Osmosis Membrane designed specifically for the NU Aqua 8-Stage Countertop Reverse Osmosis Water Filter System. This high-performance membrane is the heart of your filtration system, removing up to 99% of contaminants for the cleanest, healthiest drinking water.
The Heart of Your RO System
The reverse osmosis membrane is the most critical component of your water filtration system. This precision-engineered membrane uses semi-permeable technology to remove dissolved solids, heavy metals, chemicals, and microscopic contaminants that other filters can't capture. When your membrane reaches the end of its lifespan, replacing it ensures your system continues delivering laboratory-grade purified water.
Superior Filtration Performance
This genuine NU Aqua RO membrane removes up to 99% of total dissolved solids (TDS) including lead, arsenic, fluoride, chromium, radium, chlorine, pesticides, pharmaceuticals, and hundreds of other contaminants. The result is crystal-clear water that tastes pure and refreshing, free from the chemical taste and odor found in tap water.
