Coconut-shell carbon core
A tighter pore structure than standard carbon absorbs more odour and residue before saturating.

The current-generation filter set — four upgraded coconut-carbon cartridges and four intake sponges, sized to sit snug in the 50–108oz fountains.
Replacement filters and sponges sized for the 50oz, 95oz and 108oz fountains — the standard refresh kit.
This is the refined version of Veken’s standard cartridge. The carbon inside is refined coconut shell with a finer pore structure than generic filter carbon, which means more surface area grabbing odours and metals on every pass, and the whole media stack is wrapped in a high-density fabric that keeps dust where it belongs.
Fit is the quiet advantage. These are factory-matched to the fountain tray, so there is no gap for unfiltered water to slip around the edge — the difference between water that has been near a filter and water that has actually been through one.

High-density fabric casing stops media dust escaping and keeps the cartridge rigid in the tray.
