| Application | Final polishing for lab, medical, and industrial |
| Service Life | Varies by feedwater TDS and flow rate |
Installing Your Mixed Bed DI Filter
- Shut off water supply and relieve system pressure before opening your 20" Big Blue housing
- Remove old filter cartridge and clean housing sump with mild detergent, rinse thoroughly to remove any residual contaminants
- Insert the Aries AF-20-4011-BB into housing, ensuring center tube aligns properly with housing cap before tightening
- Flush the new mixed bed DI cartridge for 3-5 minutes at low flow to remove any fines and condition the resin bed
- Monitor output water quality with a TDS or conductivity meter to determine cartridge replacement intervals based on your application requirements
Housing & System Requirements
The Aries AF-20-4011-BB is engineered for standard 20-inch Big Blue filter housings with 4.5-inch outer diameter compatibility, including models from Pentek, Culligan, US Filter Works, and other manufacturers using industry-standard dimensions. This mixed bed DI cartridge performs optimally as a final polishing stage after reverse osmosis or carbon filtration, where feedwater TDS is already reduced below 50 ppm. For whole-house applications requiring ultra-pure water at multiple points of use, install after primary sediment and carbon stages in a multi-stage Big Blue manifold system.
