75 Gallon Aqua Membrane

Filter type: Reverse Osmosis membrane (RO / Membrane), 4th stage. Production capacity: about 75 gallons per day (approximately 280–300 liters/day). Filtration accuracy (pore size): up to 0.0001 microns, which means it removes dissolved salts, heavy metals, bacteria, viruses, and fine impurities. Salt tolerance: typically handles water with a TDS range between 950 and 1050 (according to some sources). Lifespan: recommended to be replaced every 12 to 24 months depending on water quality and usage. Compatibility: suitable for most home water purification systems (5-stage or 7-stage RO).
