The iSpring Greatwell Reverse Osmosis Membrane is a thin film composite membrane that can eliminate over 1,000 contaminants in water, including lead, chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more. Tested by independent third parties, the membrane meets NSF/ANSI standards and is made of food-grade material with high packing density. With a 0.0001 micron size, it allows only water molecules to pass through.

As the heart of a Reverse Osmosis System, each membrane is inspected under the highest industry standards and is shipped to customers only after passing quality checks. It is recommended to replace the membrane every two to three years. The dry version of the membrane sold by us can be stored longer, preserved easily, and does not require washing off preservation solutions before usage.

Our products have received positive customer reviews, with high ratings for performance and quality. The membrane is capable of removing up to 99% of contaminants, providing clean water with confidence. With a TDS rejection rate of up to 97%, it produces 75 gallons of water per day, suitable for families of any size.

At iSpring, we offer peace of mind customer service, including a manufacturer warranty and lifetime tech support. If any issues arise with our products, customers can reach out to us for immediate assistance. Depending on the source water quality, the membrane typically lasts 2-3 years, with customized solutions available for water with high TDS levels.

Overall, our brand is dedicated to providing high-quality water filtration products that ensure access to safe and clean water for every household.
