Mine is between 150-200 before the RO system. After RO its at 9. After DI its at 1. I got my unit in Jan and it looks like I already need to change my filters. I thought the DI resin was good for up to a year but its starting to show wear already. I will monitor it more but once it hits 3 Im changing it.
