The Aries FilterWorks AF-20-3400-BB is a 20"x4.5" Big Blue greensand specialty cartridge engineered to reduce iron, manganese, and hydrogen sulfide in whole-house applications.

INSTALLATION & USE
How to Install the Aries Greensand Filter
- Shut off main water supply and relieve pressure in the line by opening a downstream faucet.
- Remove sump from your 20" Big Blue filter housing and discard old cartridge if replacing.
- Insert the AF-20-3400-BB filter into the housing, ensuring it seats properly on the center standpipe.
- Lubricate the o-ring with silicone grease, thread sump back onto housing cap, and hand-tighten securely.
- Turn on water supply slowly and check for leaks. Flush filter for 3-5 minutes to clear fines before use.
COMPATIBILITY
Housing Requirements
This Aries AF-20-3400-BB greensand cartridge fits all standard 20-inch Big Blue filter housings with 4.5" diameter sumps, including brands like Pentair, iSpring, Hydronix, and US Water Systems. Ensure your housing is rated for whole-house flow rates and has a maximum pressure rating of at least 80 PSI. Greensand filters work best upstream of carbon or sediment polishing stages in a multi-stage system.
🔧 Pro Tip: Greensand filters require periodic backwashing or replacement depending on your iron and manganese levels. If you notice reduced flow or contaminant breakthrough before 6 months, your water may benefit from a larger housing or a regenerating greensand tank system instead of cartridge filtration.
