NOTE: All water purification and filtration systems are different. Please contact the manufacturer of your RO or DI system to determine when you should change your filter cartridges or membranes (based on TDS levels and/or percent rejection).
| With a TDS monitor or meter, you can easily determine your RO system's performance by calculating the percent rejection. Once you have obtained the TDS levels of your feed water (IN) and product water (OUT), use the calculator below to determine the percent rejection of your RO system.
