Reverse osmosis (RO) requires 30psi + of water pressure to work properly. The higher the pressure (to an extent) the more efficiently it works.Wow, I never considered that gravity and air pressure was enough to make a reverse osmosis system work in a cartridge. I always assumed they had better carbon filtration than the other guys. Do you recommend going full RO for the kitchen/fridge for untreated well water? Thanks in advance.
A properly prefiltered RO membrane will last >10,000 gallons and the water purity will be very high.
