These are the filters we use in the FLOW RED+ filtration system - a high-flow sediment filter, and loose, granulated, activated carbon... also for high flow rate - schedule to change this on the first day of each month to protect your RO'S from chlorine damage.
The symptom of chlorine damage is the TDS of RO OUT starts to increase. Extreme chlorine damage will result in TDS OUT being 20% of TDS IN, or higher. This MAY STILL BE USEABLE for window cleaning - as long as your cost of DI is affordable, there is no great need to change out (worst case scenario).
