About this item:
Relish Pure, Pristine Water with Utmost Assurance: Our Reverse Osmosis membrane is expertly engineered to eliminate up to 99% of over 1,000 harmful contaminants in your water. This includes the removal of up to 98% of lead, as well as chlorine, fluoride, arsenic, asbestos, calcium, sodium, and an array of other impurities.
Exceptional Quality : Our Reverse Osmosis Membrane is crafted from premium food-grade materials, ensuring exceptional capacity and packing density to effectively filter out contaminants. It permits only water molecules to pass through, excluding virtually all else.
Innovative Energy Efficiency: Operates at a low pressure of 70 psi, delivering impressive energy savings through minimized power consumption and reduced operating expenses.
Versatile TDS Accommodation: Efficiently processes high-salinity water with a Total Dissolved Solids (TDS) range up to 3000ppm, consistently maintaining a reliable rejection rate.
Consistent Rejection Rate of 97% : Advanced membrane formulations assure a stable rejection rate across a broad TDS spectrum, elevating your water purification experience.
Reassuring Customer Support : We are committed to supporting our customers. Should you encounter any issues with our products, please contact us promptly. We are eager to assist you!
