Spectrapure ATO is excellent as well. I prefer not need the pump submerged and the pressure sensing tubes are long enough the magnets are clear of the water. I like that for magnets that are typically out of sight. I ran their last gen ATO for three years without changing the peri tube with no issues. It also allows you to use your main RO reservoir and pull from across your home. Save space in the cabinet and no longer tote water. It’s also great for vacations if your RO reservoir is setup to auto fill when empty. I’ve been using their latest gen on 600g for the last year with no issues. I’d guess it tops off 40-50g a week, depending on the time of year. My only complaint is the lack of mounting options for the pump/controller.
