Details
These 21" RO Membranes are designed to operate at extremely low operating pressures making them the perfect choice for the window cleaning professional.
Consider changing your RO membrane when it has begun to remove less than 80% of the impurities in the water. The fewer impurities the RO can remove, the more you will spend on DI filter replacements.
NOT all RO membranes are created equally. Check out our video for more info.
Water Resistant Lubricant may be required and is available HERE
