About this items:
Enjoy Your Water with Confidence: Our Reverse Osmosis membrane boasts the remarkable ability to eliminate up to 99% of over 1,000 contaminants from your water. Whether it's harmful lead (removing up to 98%), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more, you can trust in pure water with every drop.
Top-notch Quality : Meticulously crafted from high-grade food-safe materials, our Reverse Osmosis Membrane ensures superior packing density. This design facilitates the exclusive passage of water molecules, effectively filtering out unwanted impurities.
Energy Saving: Designed to operate efficiently at low pressure (70 psi), this membrane reduces power consumption and minimizes operational expenses, making it a cost-effective choice for households.
Wide TDS Range: Capable of performing in saline conditions with TDS levels up to 3000ppm, while ensuring a consistent and stable rejection rate.
Stable Rejection Rate 97% : Enhanced membrane formulation guarantees a consistent and stable rejection rate across varied TDS levels, maintaining optimal filtration performance.
