Aries (AF-10-3690) 9.75"x3" Activated Alumina Filter
Aries AF-10-3690 9.75"x3" Activated Alumina Filter
Specialty filter engineered for fluoride and arsenic reduction using high-grade activated alumina media in a standard 10" housing format
Activated alumina targets contaminants carbon can't touch
Fluoride Adsorption
Activated alumina media chemically bonds with fluoride ions, pulling them from water through adsorption rather than filtration
Arsenic Reduction
Effective against both arsenic III and V compounds commonly found in well water sources
High-Purity Media
Aries uses food-grade activated alumina that meets NSF standards for drinking water contact
Standard Sizing
9.75" height x 3" diameter fits standard 10" filter housings for RO and whole-house applications
Housing requirements
The Aries AF-10-3690 fits any standard 10" x 3" filter housing. Commonly used in reverse osmosis systems as a pre-filter stage or in dedicated whole-house fluoride reduction systems. Actual dimensions are 9.75" height by 3" diameter. Verify your housing accepts a 3" diameter cartridge before ordering, as some 10" housings are designed for slimmer 2.5" cartridges.
Replacement schedule for activated alumina
Typical lifespan
Replace the AF-10-3690 every 6 to 12 months depending on fluoride levels and water usage. Higher contamination shortens media life.
Performance indicator
Test fluoride levels periodically. When removal efficiency drops below acceptable levels, replace the cartridge regardless of time elapsed.
Optimal conditions
Activated alumina works best in slightly acidic water. Consider pH adjustment if your source water is above 7.0 for maximum fluoride removal.
Specialty Filtration
Targets contaminants that carbon and sediment filters cannot address
Versatile Use
Works in both RO systems and whole-house filter configurations
Aries Quality
Made by Aries Filter Works with food-grade media and reliable construction
