Product Description
Water Filter Replacement 50G RO Membrane for Under Sink RO Drinking Water Purifier System
Product Overview
Reverse Osmosis (RO) membrane is a high-precision semi-permeable membrane made of polymeric materials like polyamide. It works by using pressure to force water molecules through its dense layer, blocking dissolved solids, bacteria, viruses and other impurities. This chemical-free physical separation ensures safe, pure water. With high desalination rate and good stability, it is widely used in household water purifiers, industrial pure water production, seawater desalination and other fields, serving as a core component for water purification.
Key Features
  • Universal Compatibility: ROYOL RO Membrane is compatible with most RO membrane housings available on the market, eliminating concerns about incorrect connections.
  • Premium Food-Grade Material: Made of food-grade material, boasting outstanding wear resistance, impact resistance, high load-bearing capacity and exceptional durability.
  • Easy Installation & Replacement: Features standard size for easy installation and replacement with a replacement cycle of 6-12 months, ensuring stable and reliable performance.

Tested several similar membranes before choosing this one, and it’s by far the best value. Performance is stable, pressure holds well, and the heavy metal filtration is exactly what we needed for our industrial setup. Great communication and fast shipping from this supplier.

We’ve been using these 3216-800 RO membranes for months in our commercial water system, and they’ve been incredibly consistent. 800 GPD keeps up with our daily demand easily, and the heavy metal removal and 97% salt rejection work exactly as advertised. Very reliable supplier, will order again.
