The iSpring MS5 500GPD Reverse Osmosis (RO) Membrane Replacement is a high-capacity, low-pressure membrane designed for tankless direct RO output. It fits the updated iSpring light commercial RO system RCS5T and boasts a 1:1 drain to clean water ratio, saving up to 60% of water. This membrane is capable of rejecting a wide spectrum of impurities down to .0001 micron and is tolerant to a wide range of operating conditions.
Users have praised the product for its efficiency and ease of use. One reviewer mentioned, 'This is absolutely the best of its kind on the market today it works flawlessly.' The customer service, particularly from Nick, has been highlighted as exceptional, with many users appreciating the support provided during product selection and troubleshooting.
However, some concerns have been raised about the lifespan of the membrane. A user noted that while it produces high-quality water quickly, it may not always reach its rated capacity of 1500 gallons. This makes it less suitable for whole-house systems but adequate for drinking water purposes.
Another issue reported involves the packaging. The RO filter media must be vacuum-sealed to maintain its integrity until use. Instances where this seal was compromised upon delivery have led to dissatisfaction and returns.
Overall, the iSpring MS5 500GPD RO Membrane Replacement is highly recommended for those seeking an efficient and reliable solution for their drinking water needs, provided that attention is paid to handling and storage conditions upon receipt.
