Hydrologic Filters - Stealth-RO / SmallBoy Green Coco Carbon Filter

Hydrologic Filters - Stealth-RO / SmallBoy Green Coco Carbon Filter is a replacement carbon filter for Stealth-RO and smallBoy for chlorine reduction and sediment reduction.

Built as a green coconut carbon water filter, it’s designed to help clean up everyday source water issues that can affect consistency. It targets rust and silt reduction along with sediment reduction, helping cut down the fine particles that can leave water looking dull or carrying grit through your setup. It also supports chlorine reduction, which is useful when your water has that typical treated-water smell.

This replacement carbon filter is made for steady performance during regular filtration. The design focuses on greater dirt load capacity, helping the filter hold more trapped particulate before performance starts to drop off. It also emphasizes flow efficiencies, which matters when you want filtration that feels consistent without becoming a bottleneck in day-to-day water prep.

Another practical benefit is reduced carbon fines, which helps the filter run cleaner sooner and keeps the experience tidy during typical system maintenance. For simple part matching, this filter replaces hl 22110, making it easy to confirm you’re selecting the correct Stealth-RO / smallBoy replacement carbon stage.

If you’re maintaining a Stealth-RO or smallBoy filtration setup and want a direct-fit green coconut carbon filter that focuses on chlorine reduction plus rust and silt reduction, this is the purpose-built replacement.
