The Aries AF-10-3003 is a 10" x 2.5" water softening cartridge that uses ion-exchange resin to remove hardness minerals including calcium, magnesium, and iron from your water supply. Designed to fit standard 10-inch filter housings, this softening filter provides point-of-use water conditioning without the need for a full salt-based softener system.

COMPATIBILITY & APPLICATIONS
Where to Use the Aries AF-10-3003 Softening Filter
This cartridge fits any standard 10-inch filter housing and is ideal for point-of-use applications where hard water causes scale buildup, spotting, or equipment damage. Use it upstream of appliances like ice makers, coffee machines, steam ovens, and water heaters where localized softening is needed without installing a whole-house salt-based system. The Aries AF-10-3003 is particularly effective in situations where calcium and magnesium levels are moderate and a compact, replaceable cartridge solution is preferred over regenerating softener tanks. It works well in both residential and light commercial settings.
💧 Pro tip: Softening cartridges have a finite capacity and cannot be regenerated like full-size softeners. Monitor your water quality and replace the AF-10-3003 when you notice scale returning or hardness levels rising. Pre-filtering sediment upstream will extend the life of the resin media.
