Key Features

• High-Capacity Filtration for Modern Homes – The Greatwell MC2 RO Membrane produces up to 200 gallons of purified water per day, delivering a consistent flow of clean, refreshing water for families, offices, and small businesses that demand reliable, high-volume filtration.
• Exceptional Filtration Performance – Effectively removes up to 99% of over 1,000 contaminants, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more. The 0.0001-micron precision layer allows only water molecules to pass through while blocking harmful impurities.
• Premium Materials & Long-Lasting Design – Constructed from food-grade, high-capacity film, the MC2 reverse osmosis water filter delivers excellent packing density, durability, and stable filtration performance. Each membrane is vacuum-sealed to ensure freshness, hygiene, and long-term preservation — keeping your filtration system safe and ready for optimal performance right out of the box.
• Universal Fit & Easy Installation – Measuring 11.75” x 2”, this industry-standard RO membrane filter replacement fits most under-sink reverse osmosis systems, making replacement quick and effortless without any special tools or adapters required.
• Reliable Support & Peace of Mind – iSpring provides lifetime technical support for all Greatwell membranes. Our U.S.-based service team is ready to help you maintain optimal system performance with confidence.
• Please note - There are wet & dry membranes in the market and the ones we sell are the dry version. Comparing to the wet version, the dry ones can be stored longer, are easier to preserve, and don't contain preservation solution that needs to be washed off before usage. The RO membrane filter normally lasts about 2-3 years depending on your source water quality. If your water is very hard (Total Dissolved Solids level above 750 ppm), please contact us for customized solutions.
