Extremely low disposal costs, less than a tenth of some cartridges. Designed to fit in a range of vessels that holds from one to over 37filters for a wide range of flow rates in competitively priced hardware. Available in 1 micron, 2 micron, 5 micron, 10 micron, 15 micron, and 25 micron--all at 99% efficiency.
