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 began 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.
