Jacobi AquaSorb 1240CS Coconut Shell Carbon Media — ¾ cu ft box (AQUASORB-1240CS-75BOX)

Premium coconut-shell activated carbon media for whole-house or backwashing carbon filters. Reduces chlorine, chloramine, taste, odor and organic compounds (VOCs). This is carbon filtration media — NOT an ion-exchange softener resin and does not remove hardness.

Coconut Shell Carbon in a Three-Quarter Box

Jacobi AquaSorb 1240CS is a high-grade activated carbon made from coconut shell, offered here in a three-quarter cubic foot box that suits smaller tanks and partial recharges. The value of coconut shell carbon lies in its structure: activation opens up a vast maze of fine pores throughout each granule, and that internal surface is where filtration happens. Organic compounds and chlorine cling to the carbon as water percolates through the bed, so what comes out the other side tastes fresher and smells cleaner than what went in.

The Problems It Addresses

Carbon media is the standard remedy for water that is safe but disagreeable. A chlorine bite, a musty odor, an earthy aftertaste, or that flat quality some tap water has all respond well to a carbon bed. Coconut shell carbon in particular is hard and low in dust, so it stands up to the tumbling and rinsing of repeated backwash cycles without breaking down quickly. That durability is part of why it is chosen so often for taste and odor duty in homes that want water they actually enjoy drinking.

How It Works in the Tank

You load this media into a backwashing filter tank equipped with a control valve, riser tube, and lower distributor, typically resting on a gravel support layer. The valve backwashes the bed on a schedule, lifting and rinsing the carbon so it stays open and effective. The three-quarter box is a practical size when you are filling a modest tank or topping up an existing bed that has settled. When taste or odor begins to return, that is the media telling you it is ready for a refresh.

Confirm Before You Buy

How much carbon a tank needs comes down to its size and how the layers are arranged, so a little planning pays off. Share your tank dimensions and the issues you want to tackle, and we will help you confirm the media and the amount. We provide the documentation we have on hand, and the Water Softener Plus team is glad to walk you through loading, backwash settings, and the initial rinse so your filter is ready to perform.
