The Aries AF-20-4223 delivers high-purity deionized water through a 20"x2.5" twin bed mixed bed DI cartridge designed for demanding whole-house and well water applications. This specialty filter from Aries Filter Works removes total dissolved solids (TDS) to produce ultra-pure water for laboratories, aquariums, and applications requiring zero mineral content.

INSTALLATION & USE
Installing Your DI Filter Cartridge
- Shut off water supply and relieve system pressure by opening a downstream faucet
- Remove housing sump from your 20" standard filter housing and discard old cartridge
- Insert the Aries AF-20-4223 cartridge into the housing, ensuring proper seating at the base
- Reinstall housing sump with lubricated o-ring, hand-tighten only to prevent cracking
- Turn on water supply slowly, check for leaks, and flush system for 5 minutes before use
COMPATIBILITY
Housing & System Requirements
The Aries AF-20-4223 fits all standard 20-inch filter housings designed for 2.5-inch diameter cartridges. This mixed bed DI filter works best as a final polishing stage after sediment and carbon filtration in whole-house or well water systems. For optimal performance and resin longevity, pre-filter source water to remove chlorine, sediment, and organics before deionization. Monitor output TDS regularly with a meter to determine when resin exhaustion requires cartridge replacement.
🔧 Pro tip: DI resin exhausts faster with high incoming TDS. Install upstream carbon and sediment filters to extend the life of your AF-20-4223 and monitor output with a TDS meter to catch exhaustion before water quality drops.
