SWT’s Carbon Block Cartridges are rugged, and extra
absorbent. All cartridges feature 95 to 99.99% efficiency at their given micron rating. They all have a
20 micron polypropylene outer wrap with a polypropylene netting for prefiltration. They also have almost
no carbon fines, and up to five times the capacity of standard GAC cartridges. These cartridges are quickly
becoming the preferred choice in carbon filtration.
